Repair welding characteristics of hb-j3 mold repair welding machine

1.Low calorific value：

Since the welding machine can complete the welding of welding wire and workpiece within tens of milliseconds (1s = 1000ms), compared with argon welding (more than a few seconds), it has less heat transmitted to the workpiece and less temperature rise in the matrix area outside the welding spot, so the matrix will not have problems such as annealing, discoloration, undercut and so on. When used with our special tungsten needle, the weld pool generated by each welding pulse is less than 2mm & sup3;, Therefore, the matrix stress is also small. Although a solder joint needs many molten pools, the stress direction of the solder joint is scattered, and the concentrated stress on the workpiece is also small, so the deformation of the workpiece after welding repair is very small。

2、The welding repair accuracy is very high：

Because the microcomputer chip is used to control the output current and time, the pulse voltage (1-99) and time (1-99) can be adjusted arbitrarily. Therefore, the corresponding welding repair parameters can be set according to different welding repair requirements, so that the 0.2mm welding wire can also be welded at will, so as to achieve the welding repair accuracy of the laser welding machine。

3、High bonding firmness：

Hb-j3 precision repair welding machine adopts fusion welding technology, which has high welding repair bonding firmness and achieves the effect of argon welding. It is suitable for various processing methods and will not have the problems of loose bonding and falling off at the welding repair。

4、Fast repair speed：

The fastest repair speed can reach 100 mm ³.
