| Abstract: | Microstructures and mechanical properties of weld joints of 45 steel had been analyzed by metallography and micro shear testing .The results showed that the microstructures and mechanical properties of the welds and the heat affected zone of weld joints were better than that of matrix.The 45 steel could get better welded joints by electron beam welding and argon arc welding |
| |
| Keywords: | micro shear weld joint mechanical property |
