| Abstract: | The cold rolled sheets were welded by laser weld technology. After the tests of bending and simulated formability on welded sheets, the influence of the weld seam on the parameters of mechanical property and formability performance were analyzed. The difference of welded sheets and raw materials was compared. The influence of the strength ratio and the thickness ratio on plastic deformation and the strain distribution were analyzed. |
