ã€China Aluminum Industry Network】 1. Wire-type welding torch is more suitable for welding aluminum materials. If you can't use this type of welding torch, try to use a shorter welding torch to keep the torch vertical; use only argon as a maintenance gas; Only aluminum guns can be used when welding aluminum. 2. If you find a problem with wire feeding, you can try a conductive head that is one size larger than the wire. 3, welding more commonly used welding wire is a softer specification wire. The other is harder (simple wire feeding), and it is primarily used in welding operations where the hardness and strength are more demanding. 4, in the beginning of the welding to do a good job of aluminum oxide layer eradication operations, the use of special stainless steel brush to eradicate the oxide layer. 5. Fill arc pits at the end of welding to avoid cracks. One way is to leave the welding torch in the bath for a few seconds after welding.
