The composition of the welded joint obtained by the two welding methods are all uniform, the hardness is higher than the matrixmetal, the comprehensive property is good.
两种焊接方法所得焊接接头成分均匀,硬度值均超过母材,综合性能良好。

It demonstrated that the experiment of hardness is likely to upset in the experiment of compression. Hardness tester indenter make matrixmetal plastic deformation and viscous flow happen.
