What brand of welding rod or welding wire for Q345B material?
Optional electrode, if the force is smaller, J502 can be used by the force of J506, J507, welding wire available, H08Mn2SiA. two welding on the line.
J507 welding rod, welding wire is TIG-J50
Q345 steel is made of E50 type electrode (GB-T5118). For low strength steel and high strength steel, welding rod should be used to match low strength steel.The welding wire is not 506. This brand is ER50-6 copper plated solid welding wire.The tensile strength of the welding wire belongs to the E50 series, and the strength of the electrode with E5003 E5015 E5016 has been constant.Q345B belongs to low alloy steel. Aka: 16Mn.ER50-6 wire, coinciding with Q345 (B) strength, has been. You can use it safely.The tensile strength of ER50-6 welds is higher than that of E5015 E5016 welding electrodes. Solid two seam welding with minimum hydrogen content.
