What is the difference between stainless steel spot welding machine and projection welding machine?
Release time:2022.04.26
Summary of information:
Stainless steel spot welding machines and projection welding machines are sometimes very similar, with only 1/100 difference. That is because projection welding is a deformation of spot welding. In many cases, only the electrode welding head is different. If it is replaced with a tapered electrode, it is called a spot welding machine, and if it is replaced with a flat welding head, it can be called a projection welding machine.

It will be much better once you understand the concepts and then look at the differences
1. Spot welding is welding directly on two superimposed flat plates. For projection welding, bumps must be made on one of the two workpieces first and then welded.
2. Spot welding can weld plates with a thickness of 0.1-6mm, while projection welding can have a thickness of more than ten millimeters as long as there are bumps, usually one thick and one thin.
3. Spot welding has strict requirements on welding point density, while projection welding is not strict as long as there are bumps.
4. Spot welding can only weld one point at a time, while knife row projection welding can have up to 20 points.
5. Most workpiece surfaces need to be cleaned before spot welding, but not for projection welding.

The biggest change is that several spots are welded together, and the shape of the electrode welding head is obviously different. Spot welding has a tapered electrode head, while projection welding uses a knife-like chrome-zirconium copper bar for welding, which is called knife row projection welding.

How to deal with surface burns after welding with copper wire butt welding machine?
Summary of information:
The copper wire butt welding machine is a multi-functional butt welding machine. It can not only butt copper, aluminum and titanium but also butt steel. The problem of surface burns usually occurs when butting hardenable steel. Location: Surface burns occur on the clamping part of the jaw rather than on the welding joint. Reason: When the clamping force exceeds

The copper wire butt welding machine is a multi-functional butt welding machine. It can not only butt copper, aluminum and titanium but also butt steel. The problem of surface burns usually occurs when butting hardenable steel.
Location: Surface burns occur on the clamping part of the jaw rather than on the welding joint.
Reason: When the clamping force is too small or the surface of the workpiece in the holding part is not cleaned well, the current distribution is seriously uneven and causes local burns. When welding hardenable steel, due to the large temperature difference between the water-cooled jaws and the workpiece, cracks can also occur on the outside of the jaws.
Solution:
Before welding, oxidized impurities should be completely removed from the clamped conductive parts of the weldment until the metallic luster is exposed. The clamping force must also be large enough. When welding alloy steel, the contact between the inner side of the water-cooled conductive block and the weldment should be made into a smooth transition to avoid cracks caused by excessive temperature differences and stress concentration.
