A TIG welder must master the gas-shielded arc welding (GTAW) technique, which involves using a tungsten electrode and a shielding gas, usually argon, to produce clean and precise welds. They must have a thorough understanding of the welder's settings, such as voltage, power and speed, and be able to adjust the parameters depending on the type and thickness of the material being welded. Before starting welding, they must prepare the materials properly, clean the edges and remove any contaminants. It is important to identify defects such as excessive melting or oxidation and correct them in a timely manner. They must also master various welding techniques and ensure high-quality joints. Safety in the workplace is of key importance, so they must follow all safety measures, including protective equipment. A good TIG welder must also be able to read technical drawings and work according to industry specifications, as accuracy and professionalism are essential on the job.
