What type of welding electrode is suitable for welding Q345 steel with 45# steel? What are the requirements for welding work?
Reply #22009-03-04
Use J506 or J502 electrodes; after preheating to 150 degrees, proceed with welding
Reply #32009-03-09
427,507 are all acceptable; preheating before welding and slow cooling after welding.

Using J506 and J507 welding electrodes should be fine
