What are the factors affecting the welding effect of CNC stud welding?

  1. Material: The welding fastness of the same material is the best, and the welding effect of iron-plated copper and stainless steel is also good, and the welding effect of aluminum and copper is not optimistic. The material of the stud is also very important. Generally, carbon steel is made of A8 material, stainless steel is made of 304 material, and 201 material can also be used, but the success rate of welding is not too high.
  2. The smoothness and levelness of the surface of the plate: paint, rust, oil, and spray paint will affect the welding effect. To be able to weld with a welding machine, the current needs to be adjusted a little larger, so that the galvanized layer on the surface can be washed away.
  3. Welding torch pressure: The energy storage welding screw is put on the small spot at the bottom of the stud. If the pressure is too large, it is likely to break the small spot at the bottom, which will affect the firmness of the welding, and can also damage the welding machine. The current adjustment is large, so as to ensure the welding effect. If the pressure is too small, it is not good. If it is too small, the welding spatter will be relatively large, and it will affect the welding fastness.
  4. Solder joints of studs: There are many studs on the market with non-standard solder joints, which will lead to poor welding fastness. The bump of the standard stud is 0.7*0.7 mm, but the bump of some non-standard studs is too large or too small, and the bump is not centered, which will cause poor welding such as virtual welding and deweldering.

When you encounter poor welding, you can check through the above aspects, and your problem will be solved soon.
