摘 要: 根据焊接过程中的影响因素及各影响因素的水平,采用正交试验设计的方法设计出正交表,找出焊接过程的各组合水平,并按照此组合水平采用激光机器人焊接系统对0.8 mm的哈氏C-276合金薄壁管做了大量试验。通过观察焊后焊缝接头的外观形貌,验证材料采用激光机器人焊接系统焊接的可行性,对焊缝形貌较好的试样进行拉伸试验,然后对焊接过程的影响因素加以优化,确定了最合理的焊接方案,为哈氏合金的应用提供一定的技术支撑。
关 键 词: 特种加工工艺;激光焊接;焊接性;正交试验设计;哈氏合金;拉伸试验

Abstract: In this paper, orthogonal test design method is used to design the orthogonal table which according to the influence factors in the welding process and the level of each influence factor, and find out each combination level of the welding process. According to this combination level, a robot laser welding system is used to research on Hastelloy C-276 alloy thin-walled tube with a thickness of 0.8 mm, and a robot laser welding system is used to perform a great deal of experiment. By observing the surface topography of the welding seam joint, this paper verifies the feasibility of the welding method that uses robot laser welding system to weld this material, does the tensile test about the specimen which has better weld morphology, and optimizes the influence factors in the welding process to find the most reasonable welding plan. The paper provides certain technical support to the application of hastelloy alloy.
Key words: special processing technology; laser welding; wledability; orthogonal test design; hastelloy alloy; tensile test
