Tackling aluminum GMAW

November 22, 2010


The reactive nature of aluminum to the welding arc, which is much more pronounced than that of other base materials, presents many challenges, including excess heat input and burn-through, porosity, poor bead appearance, poor fusion, and cracking. Technology advancements have made tackling these challenges easier by providing a balance of high travel speeds with a narrow, focused arc
