Welding Aluminium Using Mig. Using a Pulse MIG welding process for thin aluminum is about the only option because whilst Short circuit MIG is too cool and subsequently prone to cold lap due to aluminiums excellent thermal conductivity it transfers the heat away from the weld zone before good fusion can occur. Having managed my first passable aluminium welds I can understand why TIG is used for anything that needs to be neat.
Push or Pull Technique. This ensures proper gas coverage of the weld puddle. Can MIG welders weld aluminum.
Firstly Mig Welding Aluminium with a general purpose Mig Welder is not ideal a DIY type machine is even less suitable.
Ad Find China Manufacturers Of Aluminum Welding. To perform correctly without being distorted keep in mind the following features. However do be aware that not all MIG welding machines work with a dedicated aluminium spool gun look at R-Techs MIG 180 PRO MIG 250 and MTS 255 to see some machines that do. Once you can do a passable steel weld you should be able to do an aluminium weld either by welding at supersonic speed or by using a brass backer to take the heat out.
