The garbage lighter (YG-16) was the Navy’s first ship to be built with an all-welded hull. The time needed to align steel plates, drill holes for rivets, and set and drive home the bolts was significant. Riveted ships were solid and durable, but riveted hulls had drawbacks. Welding had been introduced in American ships before 1918, although none had an entirely welded hull. In addition, researchers also used a concentric nozzle with the constant electrode feed, which was a forerunner of the GMAW welding process. This patent was a pioneer of the GTAW process. The research resulted in a 1926 patent, where arc welding utilized external gas supplied around the arc. Devers used argon and helium welding atmospheres to do the research. Nevertheless, working in specific welding atmospheres inspired other inventors. However, this process was used only in particular applications. The hydrogen was changed into atomic hydrogen, shielding the arc, finally resulting in atomic hydrogen welding. Scientists Alexander and Langmuir worked in chambers where they used hydrogen as a welding atmosphere. Noticeable research in shielding the arc and weld area was done during the 1920s. In addition, the nature of the atmosphere caused oxygen and nitrogen to affect the sturdiness of molten metal that was forming the weld. With the increased popularity of welding, inventors had to deal with brittle and sometimes porous welds. However, the first electrodes were bare, resulting in poor arc performance. Still, the year 1888 is milestoned as a discovery of Stick/Arc welding. However, compared to his colleague’s work, the cast metal was transferred in a mold. Unaware of his fellow scientist’s work, a Russian Nikolay Slavyanov presented the same idea of transferring metal across an arc. To make a weld, he used the metal that melted from the electrode, which was carried across the arc and deposited into a joint. He was a pioneer of welding in the U.S., credited for creating the first bare electrode.

patent for the arc welding process in 1890. Coffin of Detroit was awarded the first U.S. Coffin, an American engineer, discovered an arc welding process and became the precursor of shielded metal arc welding. First, Nikolai Slavynov figured out how to use metal electrodes for welding. Later on, welding processes advanced rapidly. Nikolai Bernardos, inventor of carbon arc welding
