What's the difference between 422 and 506? What are their respective attributes?
506 electrodes and 422 electrodes, in addition to the strength level, the former is 50 kilograms, and the latter is 42 kg class,506 electrode for low hydrogen alkaline skin, although it can be AC and DC dual-use, but the best use of DC welding machine422 electrodes for calcium titanium acid skin, AC and DC can be
Different skin, 422 belong to the acid welding rod, 506 belong to the basic electrode. The tensile strength is 422 kg per square millimeter, 506 kg 50 per square millimeter, 42.
422 belongs to the acid welding rod, the medicine skin is the titanium calcium model, the national standard is E4303., and the welding seam tensile strength is 420MPa507 belong to the basic electrode, the drug skin is low hydrogen sodium type, the national standard is E5015., the tensile strength of the weld is 490mpa
