What's the difference between 507 and 422 electrodes?
The main difference is the intensity, a difference; another 507 are low hydrogen alkaline electrode, DC reverse; 422 is an acid welding rod, AC and DC dual-use
507 is the welding manganese steel material, and the 422 is the general steel, that is, low carbon steel
Both J422 electrode and J507 electrode are low carbon structural steel electrode, but the tensile strength of them is differentJ422 welding rod metal tensile strength is not less than 42kgf/mm2 (about 420MPa),J507 welding rod metal tensile strength is not less than 50kgf/mm2 (about 500MPa),J422 is a kind of carbon steel welding rod with titanium calcium type coating. AC and DC dual-use, can be carried out in all position welding. With excellent welding performance and good mechanical performance; stable arc, small splash, easy slag removal, and arc easily; better appearance of weld, welding width, wave narrow, thin, thick, easy welding, high efficiency.Application: used for welding low alloy steel structures with lower carbon steel structure and lower strength grade, such as Q235, 09MnV, 09Mn2 and so onJ507 is a carbon steel electrode with low sodium hydrogen type. Direct current reverse welding can be carried out in all position welding. With excellent welding process performance, stable arc, less spatter, easy to remove slag, the deposited metal has excellent mechanical properties and crack resistance, low temperature resistance, good impact toughness.Usage: used for welding of carbon steel and low alloy steel structure important (compression and dynamic), such as 16Mn, 09Mn2Si, 09Mn2V, B, A and marine D, E grade steel, also used for welding carbon steel plate and poor weldability.
