Alternating current is the standard for TIG welding aluminum with good reason. It handles the properties of aluminum well and makes nice looking welds. However, AC welding has its limitations. When you need deep penetration into thick aluminum, direct current penetrates better and delivers a better weld.

Just as different cutting tools are designed for different applications, different grinding discs are designed for different metals. For instance, some welds in high-strength, abrasive-resistant steels have been known to be ground down best with specialized discs that can chisel or chew away at the hard, high-tensile weld metal.

Aluminum alloy wheels have a tendency to crack if they get hit hard enough. How hard is enough depends on a few factors how brittle the alloy is, the design of the wheel, and the tires aspect ratio being the most important. Usually a good deep pothole or raised manhole cover is what does it.

2007-7-31However, grinding a weld will decrease strength in aluminum. Remember, this is aluminum we are talking about, not steel. Sanding, grinding, sawing...can produce enough heat to actually melt aluminum at the joint causing it to oxidize and form Al2O3. This can create porosity and defects that penetrate into the heat-effected-zone of the weld.
