TIG WELDING: TOP-QUALITY CONNECTIONS
Anyone wanting to carry out TIG welding will have to master their craft. While the welder guides the welding torch with one hand, they simultaneously add filler metal with the other hand. This not only requires a measure of coordination, but also a steady hand. The result is a spatter-free and smooth weld seam. Due to the high quality of the weld seams it produces, the tungsten inert gas welding process is used whenever the weld seam quality is of top priority, including applications in container construction for the food industry, and in the aerospace industry.
Challenges of Welding Lightweight Constructions
The welding process is also used in lightweight aluminum constructions. For example, the cabs of a cable car system require a large number of weld seams to connect the various plates and profiles. Welding in these cases can prove technically challenging, with the abrupt changes in profile thicknesses within a single seam and transitions between thick and thin material. Numerous short seams harbor further pitfalls: pores can frequently form at the start of a seam, and fine cracks at the end. In order to ensure the maximum load capacity and component safety, in addition to the best possible metallurgic properties, all seams, no matter the size, must be free from pores at the start and cracks at the end. The TIG process is best suited to overcoming these challenges.
