What are the welding techniques

Electrode arc welding: This is one of the most basic skills that welders need to master, and the quality of the weld depends on the technology of the welder.
Submerged arc welding: This is a kind of arc burning under the welding layer welding method, characterized by stable welding quality, high productivity, no arc light and smoke, suitable for welding medium thick plate structure of the long weld.
Argon arc welding: A welding technology that uses argon as a shielding gas to melt the welding material under high current and form a liquid molten pool to achieve the effect of metallurgical bonding.
Gas welding: The flame is used to heat the welding wire and the joint of the metal workpiece to melt it to achieve the purpose of welding. The commonly used combustible gases are mainly acetylene, hydrogen and liquefied petroleum gas, etc., and the combustion gas is oxygen.
Laser welding: Using a focused laser beam as a heat source for welding, suitable for the welding of miniature parts or parts with poor accessibility.
Two protection welding: carbon dioxide as a protective gas for welding, simple operation, easy to use, suitable for automatic welding and all-round welding, but the welding process can not be windy, suitable for indoor work.
Friction welding: Use the heat generated by the friction of the workpiece contact surface as a heat source, while applying pressure to the workpiece to produce plastic deformation and welding together, not only suitable for metal, but also suitable for non-metal welding.
Ultrasonic welding: The use of high-frequency vibration waves to transfer to the surface of the two parts to be welded, in the case of pressure to make the surface of the two objects friction with each other to form a fusion between the molecular layer.
