Welding Q345C steel plate with ordinary electrode?
Welding Q345C steel plate with ordinary welding rod, that is, 16Mn should use 507, ordinary welding rod welding performance is poor, hope to adopt
Common electrode.You should say that the J422 structure of low carbon steel electrode, this kind of welding rod can only weld Q235 and lower grade low carbon steel material.Q345C belongs to low alloy steel (16Mn), only J50 series welding rod can be used. Such as acid welding electrode J502, the important structure using J506, J507 and other basic electrode.
Yes. Ordinary structural steel electrode can be used, but attention should be paid to the strength of the steel. Q345 steel corresponding welding rod should be 500MPa class, that is, E50 * * * or J50 * grade electrodes, such as E5003 (or J502), E5015 (J502) and so on.
