Welding through three methods to achieve the purpose of joining, the method is as follows:
The first, welding. That is to say, the workpiece to be joined is heated, partially melted, and a molten pool is gradually formed. After the molten pool is cooled and solidified, the joint is joined. If necessary, molten filler can be added to assist. This method is suitable for welding of various metals and alloys without pressure.
The second, pressure welding. In this way, in the welding process, it is necessary to apply pressure to the welding parts, which is suitable for various metal materials and the processing of some metal materials.
Third, brazing. This method uses a metal material with a lower melting point than the base metal as a brazing material, and uses a liquid brazing material to wet the base metal, fill the joint gap, and diffuse with the base metal to realize the link weldment. This method is suitable for welding and processing of various materials, as well as welding and processing of different metals or heterogeneous materials.
It is worth mentioning that there are many kinds of energy sources for modern welding, including gas flame and arc, as well as laser and electron beam, friction, ultrasonic and so on. In addition to welding in factories, it can also be used in many other environments, such as the wild and underwater, and even in space. No matter where, welding is easy to bring security risks to the operator, so when welding to take appropriate protective measures.
