空腹钢窗的窗框、窗扇均采用闪光对焊方法焊制而成的,但是该钢窗的框、扇的挺芯分格尺寸要求还是较严的。以往,我们是采用定位棒进行分格,但由于移动较频繁,使得焊接后容易出现超差。为此,我们改用平板胎具定位。平板胎具定位过程如下:先将已装焊好的钢窗样品,套装在胎具下部紧贴平板。把待装挺芯的框或扇,放在上面,然后 Fasting steel windows and sash, sash are welded by flash butt welding method, but the steel frame, fan Ting core size requirements are still more stringent. In the past, we are using the positioning rod for sub-grid, but due to the movement more frequently, making it prone to ultra-poor after welding. To this end, we use the flat tire positioning. Flat tire positioning process is as follows: First, a good welded steel window samples, set in the lower part of the tire close to the flat. Put the box or fan to be mounted on top and then
