起重机箱形梁自由变形状态下的焊接
WELDING OF CRANE BOX BEAM UNDER FREE DEFORMATION
【摘要】 作为非专业生产起重机厂家,在无专用工装条件下,通过仔细分析焊接内应力,采取有效工艺措施,合理利用焊接变形,在自由变形状态下一次成功地进行了箱形梁的焊接。
【Abstract】 Under conditions of no special equipment of free deformation,through analyzing welding stress, adoptingtechnological measure and making use of welding distortion, the crane box beam has been successfully welded.
