| Abstract: | Based on the summarizing of laser cutting,laser welding and laser surface technique of magnesium alloy inland and overseas,the laser machining of magnesium alloy was studied.The results showed that:the kerfs of AZ31B cut by laser were narrow,fine,flat and straight,the verticality is 0.05mm,the ripples of the fracture surface were small and distributed orderly,and there was no clear heat affected zone.The weld of magnesium alloy welded by laser shaped well,there was little gas pore or no clear heat affected ... |
