摘要
Abstract
The welding assessment test research of gas shielded was conducted, for WGJ510C2 steel with high toughness, fire and weathering resistant used for building. The tests included deposited metal test, routine mechanical properties test of welded joint, tensile performance test at high temperature and microstructure analysis. The results showed that the tensile property at room temperature and high temperature both can meet the welding requirements of WGJ510C2 steel, and the impact energy value of welded joint is surplus at low temperature . Therefore, adopting gas shielded welding method and NHG-1 wire to match with WGJ510C2 steel, the comprehensive properties of welded joint can completely satisfy the welding requirements of the steel used for high-rise building.关键词
