Abstract: |
CMT welding’s low-calorie guarantees credible connection and reduce the welding heat effect on the property of slug’s matrix. With preliminary and simulation test, we verify the feasibility of surfacing copper layer on slug (D406A, quenched and tempered), determine the proper welding procedure parameters detect the welding heat effect on the property of quenched and tempered slug’s matrix, and estimate the combination intensity between copper layer and matrix (D406A).At last, CMT is successfully applied on the product according to the test. |
