Welding Wisdom for Professionals and Beginners Alike.

Aluminum has strong corrosion resistance and great thermal and electrical conductivity. These features make it useful in many industries. However, its high thermal conductivity can create welding challenges. It takes…

Welding cast aluminum to extruded aluminum is possible with proper techniques. First, clean the base metals. Use TIG welding with the right filler material and argon gas. Avoid overheating, as…

Yellow sticky residue during aluminum welding often shows contamination from zinc or tungsten. This can occur due to surface oxidation, poor gas coverage, or wet argon. To get better results,…

Aluminum butt welding model 63-160MM uses a high-quality aluminum alloy for strong, efficient welds. Its non-stick heating plate enhances welding efficiency and simplifies cleaning. This model delivers consistent results, making…

Welding aluminum is challenging because the shiny surface of the aluminum and the weld puddle reduces visibility. Andy Weyenberg, a manager at Miller Motorsports, recommends providing adequate power input. Observing…

The Miller Multimatic 215 welder is versatile. It welds aluminum from 18 gauge to 3/8 inch thickness using MIG. The amperage range is 20 A to 230 A. This multiprocess…

To prevent warpage when welding aluminum, use effective clamping and fixturing techniques. Move the welding gun back and forth while maintaining a consistent distance from the workpiece. Select a suitable…

The cooling rate of aluminum during welding greatly influences joint strength. Ideal rates are around 10-11 K/s, which lower the thickness of intermetallic compounds (IMCs). Pre-heating helps reduce cold cracking…

To weld aluminum with a spool gun, adjust the wire feed and voltage settings. Use 4043 or 5356 wire for strength. Preheat the aluminum to avoid cold lap at the…
