摘要
Abstract
At present,the longitudinal and circular seams of the in-vessel components hoisting cylinder body are mainly welded by submerged arc automatic welding,and all the welding materials used are imported welding materials,so the appli-cation research of domestic stainless steel welding wires and welding flux is very important.This study verifies the compre-hensive properties of domestic welding materials through plate welding tests,including mechanical properties and process properties,and compares them with imported welding materials.The results show that the mechanical properties of domestic stainless steel submerged arc welding wires and flux at room temperature are slightly better than those of imported welding materials,the high-temperature mechanical properties are comparable,the δ-ferrite content is similar to that of imported welding materials,and the intergranular corrosion resistance is also excellent.In addition,although there are some differ-ences in the welding process performance of domestic welding materials compared with imported ones,they can meet the us-age requirements.Therefore,domestic stainless steel submerged arc welding wires and flux can be used for the welding of the main seams of in-vessel components,with broad market prospects and application potential.关键词
