Tungsten Inert Gas
Method 141 – TIG for aluminium uses a tungsten electrode and an inert gas such as argon to protect the weld bath from oxidation. It is ideal for thin and medium thickness materials, providing clean and aesthetic welds without spatter. It is used extensively in the aerospace, automotive and marine industries where lightness and strength are important. The TIG process offers excellent control over the weld pool and minimizes thermal interference, ensuring high quality welds. Its accuracy and cleanliness make it popular for welding aluminium structures and components.
