【摘要】 通过对大熔深电子束紫铜焊缝的研究，采用横枪电子束焊接方法在含气量较高的试件上获得２５ｍｍ熔深的焊缝，并消除了气了孔、裂纹等缺陷。讨论电子束倾斜入射工件时，倾斜角度对焊缝质量的影响。更多还原

【Abstract】 Horizontal electron beam welding can gain deep penatration copper weld which is the difficult point in-manufacture and eliminates the defects of weld in the same time. The relationship between oblique angle of beam and quality of copper weld is studied. It is found that a proper oblique angle is about three degrees by which a good copper weld of 25mm penatration is, obtained just with 12kW horizontal electron beam welder and red copper of high oxygen content.更多还原
