Metal hose removal and installation before welding
Metal hose removal and installation before welding Welding:
1. Before installation, carefully remove the surface layer of the joint to be welded, remove all kinds of waste, and cleanliness of the to-be-welded area. Adjust the axial gap evenly during group calibration, and carry out precise positioning welding evenly distributed on the circle, with a length of not less than 20mm. Mandatory assembly is not allowed during installation to cause partial hardening of the weldment.
2. Considering the weak fluidity (especially lubricity) of the liquid welded metal hose, the shape of the commercial weld is generally only about 50% of the high carbon steel and about 60% of the martensitic steel. Electric welding is easy to form unwelded defects. Basically increasing the welding current of electric welding to improve the fluidity of the metal hose has little actual effect, and it will also lead to over-temperature fusion, increase the sensitivity of thermal cracks, volatilize the deoxidizer in the welded metal hose, and cause stomata. .
