Stainless steel stainless steel in Henan, stainless steel electrode should be kept dry when used. In order to prevent the crack, pit, porosity, titanium calcium based skin welding before drying 150-250, low hydrogen type of medicine before the 1H drying 200-300 for 1H. Can not repeat the drying repeatedly, otherwise the skin easily fall off.
The weld is clean, while preventing the electrode coated with oil and other dirt, to avoid increasing the carbon content of the weld and welding quality.
Henan stainless steel relief, drawing attention, can not lead in the non welding parts of the arc, the best selection and welding parts of the same material cited arc.
The arc length is generally 2-3mm and the arc is too long to produce hot cracks.. The short arc welding should be used, generally not allow the horizontal swing, the purpose is to reduce the heat and heat affected zone width, improve the weld resist intergranular corrosion ability and reduce the tendency of hot cracking.
Stainless steel relief, to prevent heat generated intergranular corrosion, welding current should not be too large should generally be ratio of about 20% of low carbon steel electrode and arc not too long, interlayer fast cooling, with narrow welding is appropriate.
The above is to provide you with the grass Jinlan embossed stainless steel welding procedure and method of relief.
