THE WELDING OF ALUMINIUM MIG TIG FUSION POCKET GUIDE Aluminium Federation of Southern Africa Second Edition: 2004 © AFSA Aluminium Welding - Bring Big Ideas to Life Aluminium can be joined in many ways - a critical requirement in fabrication as whole products are usually formed from a number of parts. Joining methods include demountable systems such as bolting as well as more permanent methods including welding, especially where continuity of joining is required. Aluminium welding is a discipline that can and needs to be learned. Correctly applied, fabricators find that an aluminium welded product is quicker to manufacture than the equivalent performing steel fabrication - and it offers a 40% mass advantage. Aluminium welding opens opportunity in fabrication. The skill levels required for aluminium welding are higher but the number of hours per volume are significantly lower. While the hours required per ton for aluminium welding are higher, the metal is three times lighter than steel with the result that overall, aluminium fabrication is cheaper. Aluminium fabrication uses commonly available tools. Welded aluminium fabrications can be repaired.
