发明名称 PULSED LASER WELDING METHOD AND EQUIPMENT
摘要 <p><P>PROBLEM TO BE SOLVED: To provide a pulsed laser welding method and equipment suitable for welding of A7000 aluminum alloys. <P>SOLUTION: In the pulsed laser welding method, A7000 aluminum alloys are welded by using a pulsed laser waveform intermittently outputted from a pulsed laser generator by controlling a control signal that increases and decreases an output level stepwise. In this method, the ratio (W/T) between the output interval T of the pulsed laser waveform from one output until the next and the pulse width W of the pulsed laser waveform is set not less than 20% but not more than 40%, thereby making the welding suitable for A7000 aluminum alloys. <P>COPYRIGHT: (C)2003,JPO</p>
