Recommended welding materials for Q420R material

Thread Content

Could you please recommend welding materials for submerged arc automatic welding of Q420R and for manual arc welding?

In my opinion, the Rm value of this steel plate should be between 590–720 MPa; for manual welding, J607 or J707 electrodes should be used, with H08Mn2MoA wire and 350 type flux
