422 what does "electrode" mean?
J422 carbon steel welding rod profile, J422 welding rod is common name (also known as brand), corresponding to international standards, welding rod model E4303. It is a kind of acid electrode, titanium calcium coating, J structural steel electrode, the tensile strength is 42 42kg/mm - weld metal, weld metal tensile strength of not less than 420MPa.
422 electrode is commonly called, corresponding to international standard brand E4303. It is a kind of acid welding rod, the coating is made of titanium and calcium, and J stands for structural steel welding rod. 42 is the tensile strength of 42kg/mm2 weld metal. The tensile strength of molten steel is not less than 420MPa, and the yield point is greater than 330MPa.Main application: used for welding low carbon steel structures with low strength and low strength. They are generally used for welding steel structures and welding of ordinary carbon steel pipes.My answer hopes to help you! Please click on the adoption bar! Thanks!
