BAIJIAN - Third party testing organization
Welding achieves the purpose of joining through the following three methods:
1. Fusion welding - heating the workpiece to be joined to locally melt and form a molten pool. After the molten pool cools and solidifies、 it can be joined. If necessary、 filler materials can be added to assist. It is suitable for welding processing of various metals and alloys without pressure 2. Pressure welding - The welding process must apply pressure to the weldment、 which belongs to the processing of various metal materials and some metal materials 3. Brazing - Using a metal material with a lower melting point than the base material as the brazing material、 wetting the base material with liquid brazing material、 filling the joint gap、 and diffusing with the base material to achieve the connection of the welded part. Suitable for welding and processing of various materials、 as well as welding and processing of different metals or dissimilar materials
