Where is the difference between 422 electrode and E50 electrode? HRB335 steel cage can use 422 electrode
Tensile strength is mainly different, HRB335 steel bar should be allowed to use 422 electrodes,
Difference between J422 welding rod and E50 welding rod:The strength of J422 is 420MPA, and the brand is E4303.E50 electrode strength of 50 0MPa, common E50155016, etc., equivalent to J506, J507, J is the electrode brand, Chinese knot Jie (structural steel) of the first spell. The parameters behind the letter include strength, skin, power supplies and so on.E is the electrode type. E refers to the electrode, and the figure in the back is usually 4 figures, indicating 12 strength, 34 welding position and welding current type and type of coating.What is the difference between the type and grade of welding rod?The model containing strips is stipulated by the national standard, and its meanings include the type of the coating, the type of alloy, the strength, the applicable welding power, etc., and the classification is very fine. The brand of welding rod is a relatively common term formulated by manufacturers. Such as electrode model E4303, the corresponding brand is J422
E50 welding rod has E5015, that is, J507 E5016, that is, J506, good crack resistance, HRB335 steel can be weldedJ422 or E4303 is low carbon steel welding rod, steel bar will crack
