If you want to do argon arc welding well, you must remember these process taboos!
Taboos of Tungsten Inert Gas Arc Welding Process 1 Avoid using DC reverse welding in general welding During DC tungsten inert gas arc welding, the heat generated by the anode is much greater than that of the cathode. Therefore, when using DC positive connection (workpiece positive connection) we...Read more -
Analysis of the causes of incomplete welding of branch pipe platform and its countermeasures
1 Introduction With the development of the oil and gas industry, the market has placed higher and higher demands on the exhaust pressure of natural gas compressors. In addition to high quality requirements for the main components of the compressor, higher and higher requirements are placed on th...Read more -
How many people can master the performance of welding heat affected zone?
The welding heat affected zone (HAZ) is different from the weld. The weld can be adjusted by chemical composition, redistribution and appropriate welding process to ensure the performance requirements, while the performance of the heat affected zone cannot be adjusted by chemical composition. It ...Read more -

Preventing the Generation of Porosity in Self-Shielded Flux-Cored Wire Welding
Porosity during welding is a common problem encountered during the semi-automatic welding of self-shielded flux-cored wires, which has always troubled welders. To this end, we analyzed the causes of pores during semi-automatic welding of self-shielded flux-cored wires and proposed corresponding c...Read more -
Test your understanding of the welding performance of metal materials
Concept of welding performance of metal materials The weldability of metal materials refers to the ability of metal materials to obtain excellent welded joints under certain welding processes including welding methods, welding materials, welding specifications and welding structure forms. If a me...Read more -
Detailed Introduction of TIG Surfacing
Argon arc cladding cladding process cladding process is a process that uses welding to pile materials with certain mechanical properties on the welding surface of the parent material. The purpose is not to weld the weldment directly to the parent material, but to obtain a welded metal welding sur...Read more -
Summary and analysis of eight major defects in welding (II)
Slag inclusion Phenomenon: Non-metallic inclusions such as oxides, nitrides, sulfides, phosphides, etc. were found in the weld through non-destructive testing, forming a variety of irregular shapes, and the most common ones are cone-shaped, needle-shaped and other slag inclusions. Metal w...Read more -
Summary and analysis of eight major defects in welding (I)
Summary and analysis of eight defects in welding Quality defects in welding engineering mainly include the following aspects: All defects that can be seen by naked eyes or low-power magnifying glasses and are located on the surface of the weld, such as undercut (undercut), weld nodules, arc pits,...Read more -
There are thousands of welding methods, not just electric welding! Have you heard of these?
Hot air welding is also called hot air welding. Compressed air or inert gas (usually nitrogen) is heated to the required temperature through the heater in the welding gun and sprayed onto the plastic surface and the welding strip, so that the two are melted and combined under low pressure. Plasti...Read more -
