在薄壁容器制造过程中,筒体外纵焊缝有时需要进行返修。但在返修时,我们发现在返修部位常因出现下陷而影响返修质量。为此,我们制造了筒体外纵焊缝返修支承架,从而有效地解决了上述问题。该筒体外纵焊缝返修支承架结构如图所示,它可根据筒体内径的大小不同来制作。其使用方法如下:将焊缝返修支承架放入筒体内,转动调节丝母,以调节高度直至顶紧焊缝,待返修完毕焊缝冷却后取下。
In the manufacture of thin-walled containers, longitudinal welds outside the barrel sometimes require rework. However, in the repair, we found that often in the repair site subsidence and affect the quality of rework. To this end, we have made the barrel outside the longitudinal weld repair support, which effectively solve the above problems. The tube outside the longitudinal weld repair support frame structure shown in Figure, it can be based on the size of the cylinder diameter to produce. Its use is as follows: The weld repair support frame into the cylinder, adjust the nut rotation to adjust the height until the top of the weld, to be repaired after the weld is cooled and removed.
