ZL114A铝合金激光-电弧复合焊接头枝晶尺寸与熔宽的关系
Relationship Between the Dendritic Length and Width of Fusion Zone in ZL114A Casting Alloy Welding Joints by Laser-MIG Hybrid Welding
摘要
Abstract
ZL114A casting alloy plate with 8mm thickness was welded by Laser-MIG hybrid welding, the size and distribution of welding joints microstructure were investigated. The results show that the dendritic length has certain correlation with the width of fusion zone in different welding joints, which obtained by different process parameters. The dentritic length can be determined when the width of fusion zone is fixed. What's more, the dendritic length shows a nearly linear decrease from top to root along the thickness direction of the welding joints.关键词
