We promise to strictly control the quality to ensure that every product meet the standard. In the meantime, we arrange production efficiently and deliver on time, so that you can receive the goods ...
First, Welding cracks and pores are generated.
The moisture absorbed by the welding rod becomes gas under the action of the welding arc heat, which decomposes hydrogen, resulting in the formation ...
Red head thoriated tungsten electrode (WT20)
Currently the most stable and widely used tungsten electrode is mainly used in the welding of carbon steel, stainless steel, silicon copper, copper, br...
Flux-cored welding wire first appeared in the United States and Germany in the 1920s. However, it was not until the 1950s that it was really widely used in industrial production, especially after t...
Shielded Metal Arc Welding (abbreviated as SMAW). The principle is: an arc is generated between the coated electrode and the base metal, and the welding method using the arc heat to melt the electr...
The welding electrodes that leave the factory have been dried at high temperature and packaged with moisture-proof material, which usually prevents the coating from absorbing moisture. However, dur...
