Is the sheet stainless steel cold welding machine the same as the argon arc welding machine?
Mainstream argon arc welding machine;

1, high current density, concentrated heat, high deposition rate and fast welding speed. In addition, it is easy to arc. Need to strengthen the protection, because the arc light is strong and the smoke is heavy, so it is necessary to strengthen the protection.

2. Because the argon arc welding current is too large and the heat affected zone is large, the workpiece often appears deformation, hardness reduction, sand holes, local annealing, cracking, pinhole, color difference, undercut and internal stress damage after welding. Especially in the process of repairing small defects in precision casting, the surface is prominent.

3. It is difficult to weld metals with low melting point and easy evaporation, such as copper, lead, tin and zinc.

Therefore, in the field of welding repair of precision castings or other precision parts, it is suggested to use cold welding machine instead of argon arc welding.

Bing Yi M4 cold welding machine:

1 and M4 cold welding machine belong to low temperature fusion welding, not zero temperature welding! The welding firmness is equivalent to the welding effect of mainstream welding machines in the market. For complete metallurgical welding, the hardness of welding material is optional, and the properties of welding material and base metal will not be changed after welding;

2. The repair precision is high, and the welding wire with the diameter of 0.2-2.0mm can be used for wire-adding welding, so that welding defects such as deformation and undercut will not occur, the original datum plane is retained, and the later shaping is also very convenient.

3. The repair speed is fast, and the fastest repair amount can reach 180mm3/min, which is almost equal to the argon arc welding speed.

4. Due to the principle that high-frequency discharge produces instantaneous high temperature, the heat affected zone of solder joint is small and the calorific value is small. After welding, you can directly touch the solder joint with your fingers, so it will not cause annealing deformation of the substrate.

5. Wide voltage adaptation range. When the voltage changes within the range of plus or minus 20%, the machine can still work normally and maintain a stable output power.

6. When the laser welding machine is welding and repairing local parts of large workpieces, it cannot be welded and repaired due to the limitation of the platform. However, argon arc welding machine can not meet its welding repair requirements because of its high welding repair temperature and low precision. M4 cold welding machine adopts portable design, which is easy to operate and flexible to use. It can weld workpieces with complex working conditions and help you solve the thorny problems of welding repair.
