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 ...
The coating plays a complex metallurgical reaction and physical and chemical changes in the welding process, which basically overcomes the problems in the welding of the photo electrode, so the coa...
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...
When welding stainless steel, the performance of the electrode must match the purpose of the stainless steel. Stainless steel electrode must be selected according to the base metal and working cond...
