Several methods and development by welding

Several methods and development trends of welding


At present, there are three methods of welding: fusion welding, pressure welding, and brazing.


1. Fusion welding: heat the workpiece to be joined and melt its part to form a molten pool. After the molten pool cools and solidifies, it can be joined. If necessary, a filler can be added to assist. It is suitable for welding of various metals and alloys, and the whole process does not require pressure.


2. Pressure welding: As the name implies, the pressure welding process must apply pressure to the weldment. It is suitable for the processing of various metal materials and some metal materials.


3. Brazing: The brazing filler metal is made of a metal with a lower melting point than the base metal, and the liquid brazing filler metal is used to wet the base metal, fill the joint gap, and realize the connection of the weldment by interdiffusion with the base metal.


Brazing is suitable for welding of various materials, especially for welding of different metals or dissimilar materials.


Welding energy sources: gas flame, arc, laser, electron beam, friction and ultrasonic, etc.


Where welding is used: In addition to being used in factories, welding can also be performed in a variety of environments, such as the field, underwater, and space.


The possible injuries caused by welding to the human body include: burns, electric shock, visual impairment, inhalation of toxic gases, and excessive exposure to ultraviolet rays.


Welding can be dangerous to the operator wherever it is, so proper precautions must be taken when welding.


Development Trend of Welding Technology

1. Improving welding productivity is an important driving force for the development of welding technology.


2. Improving the mechanization and automation level of the preparation workshop is the key development direction of the world's advanced industrial countries.


3. The automation and intelligence of the welding process is an important direction to improve the stability of welding quality and solve the harsh working conditions.


4. The development of emerging industries continuously promotes the advancement of welding technology.


5. The research and development of heat source is the fundamental driving force to promote the development of welding technology.


6. Energy saving technology is a common concern.
