Method of cast iron welding
(1) Place the workpiece tilted so that the weld is welded or semi -welded to reduce the melting ratio.(Do not forget to clean up before welding) (2) Preheat the surroundings around the ramp before welding, and the temperature is 200-250 ° C to reduce the temperature difference between the weld and the workpiece.(3) The box is cast 308, D3.2mm and 4mm in diameter.Before welding, the box should be baked by about 150 ° C for 2h.(4) D3.2mm welding stripes are used when welding the 1st, 2nd, and 3rd layers, and the current is 90 to 100A.The latter two layers of welding channels are used, and the D4MM cannibal is used, and the current is 130 to 160A.Use DC positive connection.(5) Clear slag after welding.(6) After welding, in the range of 200mm around the welding area, heated to 300 ~ 350 ° C, heat preservation for 30 minutes, and re -cave with asbestos powder to make it cold.
