The connection form of china Concentric Reducer is to directly butt weld the reducer and steel pipe. So what do you need to pay attention to when welding?
1. Use switching power supply for welding with flat characteristics, and use inversion for DC welding. It can be welded by using a general CO2 machine, but the working pressure of the wire feeder should be slightly lighter.
2. In order to avoid the occurrence of welding holes of the China Concentric Reducer, if there are rust and oil stains on the welding position, try to clean it up and clean.
3. In order to make the argon gas maintain the welding pool very well and facilitate the actual welding operation, the tungsten-grade centerline and the welding part should generally maintain an angle of 80-85°, and the angle between the filling electrode and the surface of the china Concentric Reducer should be as small as possible Small, generally around 0°.

4. China Concentric Reducer MIG welding is very susceptible to wind, and sometimes light wind causes air vents. Therefore, wind resistance should be adopted in areas where the wind is above 0.5m/sec.
5. The length of the electric isolation, the MIG welding of the stainless steel plate china Concentric Reducer is generally welded at the standard of spout connection, and the working voltage should be adjusted to the level of 4-6 mm.
