Stainless Steel Welding Electrodes
STAINLESS STEEL Welding Electrode:
Stainless steel electrode refers to a type of electrode coated with stainless steel as raw material. It can be divided into chromium stainless steel electrode and chrome-nickel stainless steel electrode, which are widely used in chemical industry, chemical fertilizer, petroleum, medical machinery manufacturing and other industries.
In addition to meeting the general welding process performance and mechanical properties of welded joints, stainless steel electrodes must also ensure that the welded joints can meet certain corrosion resistance requirements. For coatings and cores, the following requirements are generally considered:
1) Through the transition of various alloying elements through the welding core and coating, the weld metal contains a certain amount of austenite and ferrite structure, so as to ensure that the weld metal has both good crack resistance and good crack resistance. The ability of the corresponding medium to corrode.
2) Through the welding core or coating, a certain amount of carbide-forming elements (such as niobium, molybdenum, titanium, etc.) can be infiltrated into the weld metal to form stable carbides with carbon to prevent the formation of chromium carbides at the grain boundaries thing.
3) The increase of carbon will cause intergranular corrosion in the weld of austenitic stainless steel (or ferritic stainless steel), so the carbon content in the welding core and coating raw materials should be strictly controlled. It is recommended to use low carbon or super Low-carbon welding cores use low-carbon or carbon-free iron alloys and metal elements as raw materials for the coating.
4) Strictly control the sulfur and phosphorus content in the stainless steel welding core and coating to reduce the risk of weld thermal cracks.
