Welding characteristics and stress corrosion cracking behavior of nickel-based alloys 690 by laser beam and arc welding processes
博士 === 國立成功大學 === 機械工程學系碩博士班 === 98 === This study initially investigates the influences of three mean Nd:YAG laser output powers (1250, 1500, and 1750W) combined with rectangular pulse wave (PW) and continuous wave (CW) on weld bead profiles, melting ratios (MR), microstructures, and microhardnesse...
