The suitability of the different processes was analyzed by observing the weld appearance,studying the microstructure and measuring the mechanical properties of the joint.The results show that a favorable weld can be obtained under the suitable parameters by laser beam welding or tungsten inert gas welding with filler metal.The TIG welded joint has a wider HAZ,and the laser welde...

试验结果表明：在工艺参数合适的条件下，加焊丝TIG焊和激光焊均能获得成形较好的焊接接头；TIG焊接头热影响区较宽，焊缝深宽比小，而激光焊时热影响区不明显，焊缝深宽比大；两种焊接方法所获得的焊缝区组织均为均匀的等轴晶，但激光焊时焊缝组织更细，从而使接头抗拉强度大幅度提高，达到母材的94%左右。
