How to select welding rod for welding Q245R Q345R?
In the choice, should pay attention to the following points: Q245R and Q345R manual welding can use E5015 J507 welding rod, embedded welding H08MnA welding wire. Carbon wire and low alloy steel welding wire are adopted by welding wire model ER50-6, standard GB/T8110-2008 gas shielded arc welding.
Manual soldering of Q245R and Q345R can be done using E5015 J507Welding electrode, H08MnA welding wire
