Understanding TIG welding: Definition and process

TIG welding, also known as Gas Tungsten Arc Welding (GTAW), is a welding process that uses a non-consumable tungsten electrode to produce the weld. The electrode creates an arc that heats and melts the base metal and filler material, if used, forming a strong and durable bond. TIG welding is commonly used in applications that require high-quality welds, such as aerospace, automotive, and precision fabrication.

The process of TIG welding involves several key steps. First, the welder prepares the materials by cleaning and prepping the surfaces to be welded. Next, the welder sets up the TIG welding machine, adjusting the current, gas flow, and other settings to achieve the desired weld characteristics. The welder then holds the torch at the correct angle and distance from the workpiece while carefully controlling the arc and adding filler material, if necessary. Finally, the welder ensures proper post-weld cleaning and inspection to ensure the integrity of the weld.

TIG welding offers several advantages over other welding techniques, making it a preferred choice for professionals and hobbyists alike.
