Three laser welding processes (pulsed Nd:YAG, pulsed CO/sub 2/, and continuous wave CO/sub 2/) were investigated for joining 0.010-in. thick, stainless steel sheet. Objective was to determine the optimum weld process for producing a weld with at least 0.015-in. penetration with no porosity. Both tests with the pulsed beam processes and one of the continuous wave laser tests exceeded the penetration requirement, but the welds also contained porosity. The other two tests with continuous wave CO/sub 2/ lasers resulted in welds with virtually no porosity, but consistently meeting the penetration requirement was a problem.
