Area includes both the weld metal and the narrow band of material adjacent to the weld which has been affected by the heat of welding.
测试面积包括焊缝金属和焊缝附近窄小的焊接热影响区。
The results of performance measurement test show that tensile-strength, contraction of cross sectional area, elongation percentage, dynamic ductility of the weld all exceed their base metal.
焊后试件的性能测试结果表明，焊接接头的拉伸强度、断面收缩率、延伸率及冲击韧性均已超过母材。
The tensile test fracture area locates on weld seam, and the hardness near HAZ fusion line is the highest, away from the fusion line, the hardness declines and reach the parent metal hardness.
焊接接头的拉伸试验断裂部位在焊缝。焊接HAZ熔合线附近的硬度值最高，远离熔合线硬度降低，并逐渐接近母材金属的硬度。
