Welding Wisdom for Professionals and Beginners Alike.

In aluminum MIG welding, the push method is preferred. It improves gas coverage and weld cleanliness. The drag method can cause oxide build-up, lowering quality. Your choice depends on the…

Inductance settings on MIG welding machines influence the current rise after a short circuit. Low inductance creates a smooth arc, reducing spatter and improving appearance. High inductance focuses the arc,…

Aluminum grades suitable for welding include 1XXX alloys, known for high conductivity. 4XXX and 5XXX alloys are common filler metals. 6XXX alloys, like 6061, provide strength and corrosion resistance. The…

To repair aluminum lower units, use a brazing rod and a propane torch. Preheat the area for proper heat penetration without distorting the cast aluminum. Clean the crack before applying…

To find the weld size for aluminum groove welding, check the base metal thickness. For thin-wall tubes, make the weld width three times the material thickness. For materials over 3/16”,…

This video shows step-by-step instructions for repairing cracks in an aluminum intake manifold. It uses Super Alloy 5 and an oxy-acetylene torch. Key techniques include cleaning, preheating, and drilling holes…

GMAW welding of aluminum needs specific techniques and materials. Use contact tips with a bore diameter 10-15% larger than the wire diameter. Common filler metals are Alloy 4043 and Alloy…

Aluminum iso phase welding is a method for joining aluminum in isolated phase bus systems. These systems transport large electrical currents in electrical substations and power generating plants. This welding…

Smut in aluminum welding is a black residue found on welds. It forms when the boiling points of aluminum and magnesium are low compared to the heat from arc welding….
