Why is aluminum welding so difficult?
1. Aluminum has a strong oxidizing ability. Aluminum has a strong affinity with oxygen and can easily combine with oxygen in the air to form a dense and strong film, which will hinder the combination of metals during welding and easily cause slag inclusions or poor fusion; the oxide film will also absorb moisture, which will cause pores in the weld during welding.
2. Aluminum has good thermal conductivity. During welding, a large amount of heat is quickly transferred to the inside of its base metal, causing the heat to be absorbed and the welding efficiency to be low.
3. Aluminum is prone to deformation during welding, and aluminum thin plates are more deformed.
4. Aluminum is easy to melt at high temperatures. During welding, it cannot support liquid metal, resulting in poor weld formation, and even collapse or burn-through.
Therefore, aluminum welding requires certain skills and a machine specifically designed for aluminum welding.
