Gas Metal Arc Welding
Gas metal arc welding is easy for thin-gauge and heavy aluminum plate. It utilizes an electric arc welding process combined with gas. Intense heat is produced by an arc between an electrode of aluminum filler and the aluminum base metal that doesn't need to be repaired. Shielding is supplied by an external gas mixture to protect the entire welding area from other gases. Usually, Argon and helium are utilized. They provide superior protection for making deep penetration and clean welds and produce a hotter arc.
Determine Welding Joints
Examine the damaged area of the skeg and measure it to determine the dimensions of the area that will need a replacement piece of aluminum welded to the undamaged part of the skeg. Joining aluminum by welding requires a keen eye. Having the correct joint technique assures a strong bond. You must assess the aluminum's thickness, its welding position, strength required and the accessibility of the joint.
Clean the Metal
To prevent the formation of oxides, clean the aluminum. The skeg must be completely free of dirt, oil, grease and paint. This provides a stronger and smoother joint. Use a stainless steel wire brush on the edges and surface.
Steady Penetration
Jigs and fixtures keep work in proper position. All joints must provide suitable access, allowing for welding penetration. Move the torch gun along the joint at a steady speed until the gas stops. Allow the joint to cool slowly.
