| Abstract: | Based on the MAG weld defects and welding character of drilling tools, proper welding materials and technological parameters are selected and tested. It is shows that new operational technique for annular welding seam introduced in this paper can obviously decrease the quantity of porosity, crazing defects and gain lempered sorbite in the welded joint zone.This MAG welding technlque,when applied in the production of drilling tools, can effectively raise welding efficiency and reduce welding costs. |
