Experienced welders will tell you that, compared to welding steel, welding aluminum and its alloys is not difficult but different. Steel, being one of the common construction materials, most welders and myself included started by learning how to weld steel. As aluminum has especially gained market share in transportation, welding aluminum is challenged in various […]
