Q345q what kind of welding rod is used for steel welding?

Answer:

Acid welding rod, basic welding rod can be welded, but after welding strength is different, alkaline welding rod strength is big
E5015 or E5016,J506 or J507
J502 (acid welding electrode E5003): suitable for general structures of Q345-A, Q345-B;J506 and J507 (basic electrode E5016-A1, E5015-A1): Q345-B for important structures;J506 and J507 (basic electrode E5016-C1L, E5015-C1, L): Q345-C for important structures;J506 and J507 (basic electrode E5016-G, E5015-G): Q345-D for important structures;J506 and J507 (basic electrode E5016-E, E5015-E): Q345-E for important structures.
