Welding Aluminum Vs Steel. The challenges to spot welding of aluminum compared to steel include a tenacious and rapidly forming oxide layer of variable thickness and composition high electrical and thermal conductivities small increases in resistivity with temperature a narrow plastic range low melting temperatures and a high coefficient of thermal expansion. As the filler material and aluminum base metal become liquid during the welding process they absorb hydrogen and can.

However there are some workarounds and alternatives that might provide acceptable results. Ad Find China Manufacturers Of Aluminum Welding.
When youre welding aluminum you need to be careful.
To avoid overheating the inserts during welding its good practice to perform the aluminum-to-aluminum weld first. First dip the steel into melted aluminum to coat it.
