摘要
Abstract
Objective To evaluate the mechanical properties of laser-welded titanium frameworks under the different interface morphology. Methods 20 standard pure wrought titanium samples were prepared. Each of 20 samples was sectined into 2 parts and the 2 parts were welded under the same laser welding conditions.The mechanical properties of the samples were examined by naked eye observation,SEM observation and multifunctional tests. Results There was not significant differences in breaking force between 2 welded groups (P<0.05).No porosities and cracks and other defects were found. Conclusion Under appropriate conditions (Pulse duration:10ms or 12ms;Spot diameter:1mm; Working voltage:>305V),two different interface morphology are no significant impact on the welding surface mechanical properties. 关键词
