焊接工字形结构,很容易变形,如图1,变形的焊件要花很长的时间来矫正。我厂青年工人王志强同志想出了一种方法,利用反变形法,来纠正焊件变形,效果很好。反变形法是先把焊件会变形的部分,在没有焊接前按照变形的大小,向相反的方向弯出适当的弯度,使焊接后由于变形的原故,恢复到原来的状态。使用这种方法,省去了矫正焊件变形的工时,同时还提高了产品质量。
Welded I-shaped structure, it is easy to deformation, as shown in Figure 1, the deformation of the weldment takes a long time to correct. Comrade Wang Zhiqiang, a young worker in our factory, came up with a method to correct the deformation of the weldment by using the anti-deformation method, and the effect is very good. Anti-deformation method is the first part of the deformation of the weldment, in the absence of welding in accordance with the size of the deformation, in the opposite direction to bend the appropriate camber, so that due to the deformation of the welding after the return to its original state. Using this method, eliminating the need to correct the deformation of welding work hours, but also improve product quality.
