Rules and Guidelines for Aluminum Welding

For both new and experienced welders, aluminum welding can be challenging. Over-welding of the aluminum alloys can easily happen because of its “higher thermal conductivity and low melting point. Also, feeding aluminum welding wire during gas-metal-arc-welding (GMAW) presents a challenge because the wire is softer
