TIG welding is the preferred process across demanding industries — aerospace, food manufacturing and marine among them — because it produces exceptionally clean, precise welds with excellent control of heat input. TIG consumables are commonly classified to BS EN ISO and AWS standards, which identify chemical composition, mechanical properties and intended applications.
Why is TIG welding used in aerospace?
TIG welding produces exceptionally clean, precise welds with excellent control of heat input. This makes it ideal for aerospace components where quality, reliability and repeatability are critical. Many aerospace alloys are welded using specialist TIG procedures, and pulse TIG is often used for its fine control on thin and heat-sensitive materials.
Why is TIG welding used in food manufacturing?
Food manufacturing requires hygienic, corrosion-resistant welds that are easy to clean. TIG welding produces smooth, high-quality welds with minimal spatter, making it the preferred process for stainless steel pipework and processing equipment. Back purging is often essential to maintain corrosion resistance — see our TIG welding stainless steel guide for how purging prevents sugaring on the rear of the weld.
Why is TIG welding used in marine applications?
Marine environments demand excellent corrosion resistance. TIG welding allows precise control when joining stainless steel and aluminium components used in boats, offshore structures and marine equipment. Using the correct filler rod helps maximise durability in aggressive environments — for marine stainless steel, that often means a molybdenum-bearing rod such as 316L, as covered in our TIG filler rod guide.
Which standards apply to TIG welding?
TIG welding consumables are commonly classified to BS EN ISO and AWS standards. These classifications identify chemical composition, mechanical properties and intended applications. Using recognised standards helps ensure compatibility and quality. For wider guidance, see our welding standards and compliance hub.
