Summary of welding techniques for aluminum welding and self-shielded flux-cored wire welding processes

【Summary Description】 Aluminum welding: 1. The most suitable for welding aluminum is the wire drawing welding torch. If you can't use this welding torch, try to use the shortest welding torch to keep the welding torch straight. Only argon can be used as a protective gas. When welding aluminum, only push gun method can be used. 2. If you find a wire feeding problem, you can try to use a conductive tip that is one size larger than the wire. 3. The most commonly used welding wire for welding aluminum is the softer standard wire. The other is harder (easier to feed wire) and is mainly used for welding operations that require hardness and strength. 4. Before welding, remove the oxide layer on the aluminum surface and use a special stainless steel brush to remove the oxide layer. 5. Fill the pits at the end of welding to prevent cracks. One method is to place the welding gun in the molten pool for a few seconds after welding. Self-shielded flux cored wire welding: summary of welding techniques for welding processes 1. Use pull (or drag) gun technology when welding. 2. Keep the welding wire clean and dry to achieve the best welding effect. 3. This type of welding is similar to stick welding, and the slag layer on the surface of the weld must be removed after welding. Slagging hammer and wire brush can be used for slag removal. 4. Self-shielded flux cored welding does not require an additional shielding gas container. (The protective agent is inside the wire). This feature makes it very suitable for outdoor work, because when used outdoors, the protective gas is easily blown away. 5. In the welding of thin plates, self-shielded flux-cored wire welding is more difficult than MIG welding.
