You can use gas tungsten arc welding (GTAW) or gas metal arc welding (GMAW) for the repair. You can use either 4043 or 5356 to make the repair, although 5356 is usually used on molds for textured parts. The reason is that 5356 is harder and machines more like 7075, so the texture looks more like the original mold plate.
The problem is that while most aluminum alloys are very weldable using a fusion welding process (any process that melts the aluminum, such as GTAW, GMAW, and laser welding), some are not. The alloy 7075 falls into the unweldable category.

John, unfortunately difficult or practically impossible venture to not only TIG- but generally arc-weld Alloy 7075 without cracking. The reasons are being founded on real complex metallurgical reactions of the alloy in case of melting, e.g. by arc welding.
Aluminum Round Tube 6061 is the most commonly used aluminum for structural applications. It has above average corrosion resistance, good machinability, and is excellent for welding, and approximately twice the strength of 6063 Aluminum. We also carry Aluminum Round Tube in 2024, 6060 Metric, 6063, and 7075.
However, there are exceptions. 7003 and 7005 extrusion alloys and 7039 plate alloy can be welded with 5356 or 2319 welding wire. They both yield porosity-free welds that match the integrity of the parent alloy.
Aluminum Round Tube 7075 is primarily used in the aerospace industry as it is the strongest Aluminum grade. 7075 has the strength of many steels, while retaining Aluminum’s lightweight qualities and corrosion resistance. We also carry Aluminum Round Tube in 2024, 6060 Metric, 6061, and 6063.
Aluminum 7075. When it comes to welding, the resistance welding is preferred, while gas and arc welding should be avoided. It is available in in the clad (Alclad) form to improve corrosion resistance. All of the Aluminum 7075 available from Continental Steel meets or exceeds a variety of specification including those from AMS,...
