Welding Wisdom for Professionals and Beginners Alike.

Gas Tungsten Arc Welding (GTAW), or Tungsten Inert Gas (TIG) welding, is the main method for welding aluminum. This technique employs a non-mechanical wire feeding process. It helps overcome feedability…

Forged aluminum wheels can be difficult to weld because of alloy restrictions. Alloys like 2XXX and 7XXX may lose strength during welding. While TIG welding is an option, it risks…

Pulsed MIG welding improves aluminum welding by controlling heat input. This reduces warping and spatter. It works well on different material thicknesses and uses a push-pull gun for consistent feeding….

To weld diamond plate aluminum, start by cleaning the surface with acetone and a wire brush. Use a spool gun for MIG welding and select the right aluminum filler wire….

Spot welding aluminum sheet joins aluminum pieces using high welding current. This process needs about 30,000 to 40,000 amps due to aluminum’s low electrical resistivity. Clean surfaces and proper electrode…

Aluminum bike frames can be re-welded reliably, but their strength won’t equal steel. Welding can soften the material and affect its alloy temper. Heat treatment is often necessary to restore…

To MIG weld aluminum, set the voltage between 21-24 volts and wire feed speed to 250-470 IPM. Use DCEP polarity and preheat the aluminum to around 200°F. For better heat…

DCEN, or direct current electrode negative, is preferred for welding aluminum because it reduces oxidation. Aluminum’s high sensitivity to oxidation forms aluminum oxide on its surface. This oxide layer makes…

Sandblasting aluminum before welding cleans the surface but may quickly create an oxide layer. Use suitable blast media and keep pressure low to prevent warping. Avoid sandblasting for critical applications,…
