Guide to the Long History of Welding

History of Welding: Early Uses, Inventor and Modern Advancements

The process of welding as we know it today uses a variety of sophisticated methods, tools and energy sources. Welding has a long history that can be traced back to the Bronze Age, with the use of rudimentary tools to join softer metals like copper and bronze. Blacksmiths in the Middle Ages mastered the process of forge welding, heating iron in a charcoal furnace and hammering overlapping metal ends to bond them.

The discovery of acetylene in paved the way for oxyfuel welding and cutting. The 20th century saw advancements in arc welding, including the development of shielded metal arc welding (SMAW) and gas metal arc welding (GMAW). The future of welding is expected to involve more environmentally friendly materials and the use of computer chips to indicate the lifecycle of welded materials.

What we&#;re capable of today is the result of a long history of scientific discovery and innovation. Let&#;s take a look at the use of welding throughout history and how the trade continues to evolve.

When Was Modern Welding Invented?

Welding as we know it today began in the 19th century. In , English chemist Edmund Davy discovered the chemical compound acetylene. This discovery made oxyfuel welding and cutting a possibility years later.

Who Invented Modern Welding?

It&#;s common to wonder who invented welding. Nikolay Gavrilovich Slavyanov is considered the inventor of welding, as he introduced arc welding with metal electrodes. However, the basic concept of welding was around before his time.

Welding History Timeline

Early history

When did welding start? Welding&#;s beginnings can be traced as far back as the Bronze Age. Softer metals like copper and bronze were joined using rudimentary tools. Some of the oldest artifacts known to man were constructed using welding, including small circular boxes with pressure-welded lap joints that date to sometime between and B.C.

Iron tools and weapons from ancient cultures like Egypt have been dated to around B.C. The furnaces and hammers used to create these artifacts set the stage for blacksmithing.

Middle Ages

Throughout the Middle Ages, blacksmiths started to master the process of forge welding. They would first heat the iron in a charcoal furnace and hammer out any imperfections. Then, increasing the heat, they would hammer overlapping metal ends until they bonded. Common items made by those blacksmiths included weapons, armor, chains and ornaments.

English chemist Edmund Davy discovered the chemical compound acetylene in . While acetylene wasn&#;t used in welding at the time, Davy&#;s discovery made oxyfuel welding and cutting a possibility years later.

Edmund&#;s cousin, Sir Humphry Davy, had discovered arc lighting at the beginning of the 19th century. Auguste De Meritens, a French electrical engineer, used that discovery to weld lead plates for storage batteries. Within the same year, both De Meritens and his student, Nikolai Bernardos, patented the process for carbon arc welding.

As the 20th century neared, the implementation of metal electrodes improved arc welding. Russian inventor Nikolay Gavrilovich Slavyanov is credited with the idea of transferring melted metal through an arc. But it was Charles L. Coffin, an American, who patented the process we know today as shielded metal arc welding, or SMAW.

Early 20th century and World War I

At the turn of the century, a torch suitable for using acetylene was developed, vastly improving gas welding and cutting processes. At the same time, the concept of the coated metal electrode was being developed in both Great Britain and Sweden.

These electrodes consisted of iron wire dipped in mixtures of carbonates and silicates and then left to dry to create the coating. Additionally, this time saw the development of resistance welding.

Part of the reason the beginning of the 20th century saw so many improvements in welding practices was the demand created by World War I. Many companies began producing commercial welding machines and electrodes to improve the reliability of weapons, ships, planes and tanks.

Once the war ended, the American Welding Society, a nonprofit organization, was created to continue improving welding processes in America.

The s

Several notable advancements were made during the s. For instance, the General Electric Company introduced automatic welding, which allowed for a continuous feed of bare electrodes. Electrodes themselves were improved as well.

In an effort to diminish porous and brittle welds, techniques using different gases were developed. Irving Langmuir used hydrogen as a welding atmosphere, whereas H.M. Hobart and P.K. Devers used argon and helium.

The s

Throughout the s, welding grew more popular at construction sites and shipyards. This is largely due to the development of stud welding.

Similarly, submerged arc welding, which uses an electrode with a thick, granulated layer of flux made from calcium, magnesium, silicon and other compounds become popular for a number of reasons:

• It&#;s quicker.
• It&#;s more cost-effective.
• It doesn&#;t spatter the weld.

This welding method remains popular today for the same reasons!

The s

Although Coffin, Hobart and Devers all contributed to the development of gas tungsten arc welding (or GTAW), it was Russell Meredith who perfected the process in by using a tungsten electrode arc and helium as a shielding gas.

In , the tungsten electrode was replaced with a continuously fed electrode wire. This innovation was developed at the Battelle Memorial Institute in Columbus, Ohio, and is referred to as gas-shielded metal arc welding, or GMAW.

Like submerged arc welding, GMAW became popular because it was much more cost-effective than GTAW.

The s

K.V. Lyubavskii and N.M. Novozhilov made steel welding even more economical by using carbon dioxide as the shielding gas.

Five years later, in , the size of the arc used in the GTAW process was diminished so welders could accomplish more refined work. Just a year later, an electrode that didn&#;t require external gas shielding, called the inside-outside electrode, was created.

The s were full of welding innovations. Other novel processes included:

• Electron-beam welding process: As its name implies, this method uses a focused beam of electrons as a heat source. It became popular in the American automotive and aircraft engine industries.
• Friction welding: Developed in the former Soviet Union, the process generates heat using rotational speed and upset pressure.
• Electroslag welding process: This method uses a consumable guide tube and allows for the welding of thick materials in a vertical position.

The s

Similar to the previous decade, the s witnessed a variety of innovations. Notables included:

• Spray-type arc transfer: This method produces a vaporized spray of the electrode metal that makes for a high-quality finish.
• Electrogas: A method for vertical welding similar to electroslag, only it uses a flux-cored electrode wire and a gas shield supplied externally.
• Laser welding: The powerful heat source gives this process advantages like higher speeds, strong weld joints and a diminished likelihood of cracking. It&#;s used in robotic automotive and industrial manufacturing.

Future Welding Trends

Progress never stops, which means that there&#;s a good chance the process of welding will continue its dynamic history well into the future.

There is a trend where engineers are seeking to produce welding materials that require less energy in order to make them more environmentally friendly. And some are speculating that welded materials will be able to indicate where they are in their lifecycle by means of computer chips.

As the future of welding evolves, one thing is clear: It will get more and more complex. Getting a proper foundation by completing a formal welding course can help welders adapt to the changes more easily.

How To Train To Become a Welder

Does a welding career sound exciting to you? Welding is a specialized career that requires proper training. For those who are creative and detail-oriented, this can be an exciting, fulfilling career.

A high school diploma or GED is typically required to become a welder, as well as some form of training, whether it&#;s on the job or through a technical school.

Attending a formal training program, like UTI&#;s Welding Technology program, can equip you with the knowledge and skills you&#;ll need to pursue a career in the field.1 It can also help you to stand out to employers when applying for jobs.

Over the course of just 36 weeks, students in the program train to become combination welders by learning four different welding techniques:

Upon graduation, students will be well prepared to test for welding certifications. They can also take advantage of the resources offered by UTI&#;s Career Services team, which works with national dealerships, distributors and employers across the country to identify potential jobs for graduates.

In Review

What is the oldest type of welding?

Forge welding is considered to be the oldest type of welding. Blacksmiths used this type of welding to make weapons, armor, chains and ornaments. To do so, they would heat the iron in a charcoal furnace and hammer out imperfections. From there, they would increase the heat and hammer overlapping metal ends until they bonded.

What are the 4 types of welding?

The four types of welding are gas metal arc (GMAW), shielded metal arc (SMAW), flux-cored arc (FCAW) and gas tungsten arc (GTAW).

When was MIG welding invented?

Metal inert gas (MIG) welding was patented for welding aluminum in . In this type of welding, a continuous solid wire electrode travels through the welding gun (a shielding gas to shield the process from contaminants in the air) and into the weld pool. Today, it&#;s one of the most commonly used welding processes.

What is the history of TIG welding?

Charles L. Coffin, H.M. Hobart and P.K. Devers all contributed to the development of tungsten inert gas (TIG) welding, but Russell Meredith perfected the process in by using a tungsten electrode arc and helium as a shielding gas. This transformed the welding industry, as welders were able to make products like airplanes and ships faster than ever.

When did stick welding start?

Coffin patented the process we know today as stick welding, or shielded metal arc welding (SMAW), in .

Clues about the background of welding can be gained by looking at the roots of the English word itself, which has its roots in Scandinavia. Although some may think that &#;weld&#; comes from the Old English word &#;weald,&#; this actually referred to a forested area and became the modern English word &#;wild.&#; The Old English for iron welding was &#;samod,&#; which means &#;to bring together,&#; or &#;samodwellung,&#; which means &#;to bring together hot.&#;

However, weld actually comes from the later Middle English verb &#;well&#; (wæll) or &#;welling&#; (wællen), which means 'to heat' (to the maximum possible temperature) or 'to bring to a boil'. The past-tense participle of this verb is &#;welled&#; (wællende). It was first recorded in a version of the Christian Bible from that had been translated into English by John Wycliffe. The original English version, taken from Isaiah 2:4, read, "...thei shul bete togidere their swerdes into shares..." (they shall beat together their swords into plowshares), but Wycliffe&#;s fourteenth century version was changed to, "...thei shullen welle togidere her swerdes in-to scharris..." (they shall weld together their swords into plowshares).

As with a great many English words, the root of the word &#;well&#; goes back to Scandinavia and the Vikings (in this case Swedish) with their word &#;valla,&#; meaning to boil. Although Sweden was a large exporter of iron during the Middle Ages valla was only used in relation to joining metals when used alongside the word for iron (järn), as in valla järn ('to boil iron').

Of course, other languages had their own words for welding (or &#;boiling&#;) iron, including the Illyrian (Greek) word &#;variti,&#; the Turkish &#;kaynamak,&#; the  Grison (Swiss) &#;bulgir,&#; and the Lettish (Latvian) word &#;sawdrit&#; (meaning 'to weld or solder', which was derived from &#;wdrit,&#; again meaning 'to boil').

Since the history of joining metals goes back several thousand years, it is pretty much impossible to know who was the first person to invent welding. Early examples of welding date back to the Bronze Age (from around 2,000 B.C. to 700 B.C.) and the Iron Age (from between B.C. and 600 B.C) in Europe and the Middle East, but there is evidence of welding in Egypt going back to around 3,000 B.C.

The ancient Greek historian Herodotus claimed, in his &#;The Histories&#; from the 5th Century B.C., that Glaucus of Chios &#;single-handedly invented iron welding,&#; although it is unlikely that he was actually the world&#;s first welder.

Regardless of who was actually the first person to use welding to join metals, there were many advances in forge welding during the Middle Ages (around 500 A.D. to A.D.), when blacksmiths would beat heated metal to form a bond and create all manner of items, including decorative pieces, tools and weapons. By A.D., Vannoccio Biringuccio published his &#;De La Pirotechnia,&#; which included descriptions of forging as, by this time in Europe (the Renaissance), craftsmen had become skilled in the process.

The beginning of what was to become modern welding can be traced back to the discovery of the short-pulse electrical arc by Sir Humphrey Davy in , with the results being published in . Elsewhere, Russian scientist Vasily Petrov created the continuous electric arc in , publishing the results of his experiments in &#;News of Galvanic-Voltaic Experiments&#; in . In the description of his results, Petrov wrote of a stable arc discharge, indicating that it could have numerous uses, including for melting metals. Humphrey Davy, meanwhile, unaware of Petrov&#;s work, rediscovered the continuous electric arc in , but it wasn&#;t until -82 that it was used for welding, when the Russian, Nikolai Bernados and the Pole, Stanislaw Olszewski created the world&#;s first electric arc welding technique, carbon arc welding, with the use of carbon electrodes. The associated patent officially made this invention the first welding machine.

 Over the ensuing decades there were numerous advances in welding technology as well as developments to existing processes. To provide a full picture of how welding has developed over the years, it is worth providing a timeline of events&#;

The history of welding goes back thousands of years, but really started to pick-up pace in the latter years of the 19th Century with what could be considered the advent of modern welding techniques.

They also experimented with two electrodes &#; starting with carbon but changing to tungsten electrodes &#; and began to use atomic hydrogen in the arc. The atomic hydrogen was blown out of the arc to create a heat that was 50% hotter than an oxyacetylene flame, creating the atomic hydrogen welding process. While this process was primarily used during the s and s it never became popular.

This process was later licensed to Linde Air Products who developed the water-cooled torch.

A.D.

The Battelle Memorial Institute, working under sponsorship from the Air Reduction Company, develops gas metal arc welding (GMAW), also known as metal inert gas (MIG) or metal active gas (MAG) welding. The process used a gas shielded arc similar to that used in gas tungsten arc welding, but replaced the tungsten electrode with a continuously-fed electrode wire. The process was improved through the use of small-diameter electrode wires and a constant voltage power source. The principle had already been patented by H E Kennedy and the process was originally introduced to weld nonferrous metals. Higher deposition rates meant that the process began to be tried for welding steel, however the high cost of inert gas hampered the spread of this technique at the time. It was first patented for aluminium welding in .

A.D.

Lyubavskii and Novoshilov announce the use of consumable electrodes in a carbon dioxide gas atmosphere, creating CO2 welding. This used much of the same equipment developed for inert gas metal arc welding, but was able to economically weld steels. Over the following years, the diameter of the electrodes being used were reduced, meaning that lower currents could be used. This led to the appearance of short-circuit variants such as micro-wire, short-arc and dip transfer welding in late -. These variants meant that all-position welding was now possible on thin materials and became the most popular of the gas metal arc welding processes. Also in , Soviet scientist, N F Kazakov proposes diffusion bonding.

A.D.

CO2 welding is developed further with the introduction of a special electrode wire, called an inside-outside electrode, which had a tubular cross-section that contained the fluxing agents within. Called Dualshield, this process used both the gas produced by the flux as well as an external shielding gas. Invented by Bernard in , it was patented in after being reintroduced by the National Cylinder Gas Company.

Electroslag welding is introduced by the Soviets at the Brussels World Fair of . Although it had been used in the Soviet Union since , based on work undertaken by R K Hopkins in the United States (with patents granted in ), this process was not much used for joining.  The process was perfected and equipment was developed at the Paton Institute Laboratory in Kiev, Ukraine and at the Welding Research Laboratory in Bratislava, Czechoslovakia. It was soon picked up by the Electromotive Division of General Motors in Chicago, who called the process Electro-Molding and used it to manufacture welded diesel engine blocks.

A.D.

A new inside-outside electrode was produced that didn&#;t require external gas shielding, named Innershield.

A.D.

A new welding variation using inert gas and small amounts of oxygen for a spray-type arc transfer is developed. This became popular during the early s as another variation, using a pulsed current is introduced. The laser is also invented in by Theodore Maiman at Hughes Research Laboratories, leading to the development of laser welding over the following decades.

A.D.

The Arcos Corporation introduces Electrogas welding, based on electroslag welding but using a flux cored electrode wire alongside an externally-supplied shielding gas. This open arc process doesn&#;t use a slag bath. It was developed further to use self-shielding electrode wires while another variant was created using gas shielding and a solid wire. These methods allowed for the welding of thinner materials than were possible with electroslag welding.  Elsewhere, The Welding Institute begin the first studies into friction welding in the UK.

A.D.

Originally invented in the Soviet Union by Klimenko, friction stir welding is experimentally proven and developed into a commercial technology by Wayne Thomas of TWI, at which point it receives a patent in the UK.

A.D.

TWI develops the ClearWeld method for welding plastics using a layer of infrared absorbing dye between two plastic parts and a laser beam which is absorbed by the dye, heating it up to melt the plastic and creating a join under pressure.

The timeline above is not exhaustive as there have been numerous developments and modifications made to welding processes over the years, with TWI being influential in this field through our welding research work.

Modern welding has developed to be fast, accurate and effective, with over 90 different welding processes now in existence and being used in industries ranging from aerospace to nuclear power, and construction to shipbuilding.

Welding techniques have not only evolved in their effectiveness but also in the levels of safety and sustainability. Modern inspection techniques have also reduced instances of weld defects and imperfections, allowing for higher standards across industry.

While TWI famously developed friction stir welding, this has also led to more recent advances, such as the development of the Coreflow technique for creating subsurface channels in materials using the friction process.  Friction processes have also been developed at TWI to weld wood, with ongoing research having caught the attention of both industry and academia.

This work continues at TWI and other research technology organisations around the world, proving that there are still plenty of possible welding advances to be discovered yet.
