锌箔对不锈钢和镁合金焊接接头的质量影响
The influence of zinc layer on the quality of stainless steel and magnesium alloy welded joints
摘要
Abstract
In this study,magnesium alloy and stainless steel were laser welded using zinc sheets of varying thicknesses as the interlayer.The phase composition of each region was characterized through optical microscopy and scanning electron microscopy,while the hardness distribution across the weld joint was evaluated via microhardness testing.A zinc layer thickness of 0.1mm yielded optimal weld joint performance.Under welding conditions of 3.8kW power,9.0Hz frequency,0.8mm/s speed,and a shielding gas flow rate of 7L/min,a fine and uniform grain structure was achieved.The maximum hardness values for stainless steel,magnesium,and zinc were 296.4HV,72.3HV,and 110.3HV,respectively.This research holds significant theoretical and practical value for advancing the welding of magnesium alloy and stainless steel dissimilar materials.关键词
