Welding is included in the process of the steel pipe leg. Today we will come to know the welding process.
Welding: Also known as welding or splicing, it is a manufacturing process and technique for joining metals or other thermoplastic materials such as plastics in a heated, high temperature or high pressure manner. Welding is achieved by the following three ways:
1. Fusion welding--heating the workpiece to be joined to partially melt it to form a molten pool. The molten pool is cooled and solidified and then joined. If necessary, it can be added to the filler. It is suitable for the welding of various metals and alloys. pressure.
2, pressure welding - welding process must apply pressure to the weldment, belonging to the processing of various metal materials and some metal materials.
3. Brazing--The metal material with lower melting point than the base material is used as the brazing material, the base material is wetted by the liquid brazing material, the joint gap is filled, and the joint material is diffused with the base material to realize the link weldment. Suitable for welding of various materials, also suitable for welding of different metals or different materials.
