| titleOfInvention | Preparation method of MIG welding wire with fluorine-containing coating for aluminum and aluminum alloy |
| abstract | The invention relates to a preparation method of MIG welding wire for aluminum and aluminum alloy with fluorine-containing coating, which comprises the steps of drawing an aluminum or aluminum alloy wire rod to form a wire rod with the diameter of 0.8-3.2 mm, sequentially carrying out surface pretreatment, alkali washing, water washing, film forming and heat treatment, and then carrying out layer winding to obtain the MIG welding wire; the surface pretreatment process comprises pre-pretreatment and post-pretreatment, the surface state of the substrate is activated through the pre-pretreatment, so that the surface of the substrate is in an acidic state, the post-pretreatment increases the surface roughness of aluminum and aluminum alloy wires, dense micropores are formed, and the binding force of the coating and the substrate is improved; a fluorine-containing coating is formed on the surface of an aluminum or aluminum alloy wire by a film forming process. The preparation method of the MIG welding wire with the fluorine-containing coating for aluminum and aluminum alloy can reduce the number of weld pores by more than 20 percent and the average wire feeding resistance by more than 35 percent, and is particularly suitable for automatic robot welding. |
