by Most Research Publications in the world in 2019

The Gas tungsten arc welding top 50 is Discovery PatSnap’ annual ranking of the top 50 Most Research Publications Gas tungsten arc welding Key Players in the world. Discovery has identified the top key players, startups & unicorns, fast-growings, news entrants in 2019, ranking from differnt perspectives, including patent filing intensity, academic research capability, news media heat. The company list is generated from various data types.
Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode is protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or helium), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. When helium is used, this is known as heliarc welding. A constant-current welding power supply produces electrical energy, which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma.
