【Abstract】 The weldability and welding technology of the stainless steel00Cr26Ni6Mo4CuTiAl was studied. As it turned out that when the strength of the welddeposit was lower than the base benal, the cracking-free welding joint could beobtained through preheating (200℃), by controlling the temperature between two passes(＜200℃) and selecting low heat input (0.78KJ/mm). Its mechanical properties wereslightly lower than base material, and the pitting corrosion resistance was equal to thebase material.更多还原
