我厂生产的锅炉,其对接焊缝大部分采用自动埋弧焊工艺。由于焊偏往往造成焊缝中存在未焊透缺陷。为解决焊偏问题,利用聚焦光点制作了一个指示器(见图),安于焊机机头前面。通过两个聚焦凸透镜将小电珠的散射光聚成一个明亮的小光点,直接照在工件的接缝上,操作者可通过光点所处位置来判断是否焊偏及时调整焊丝位置。随工件大小不同,可通过调节螺丝随意调整调焦筒与工件的距离,以
I plant the boiler, most of its butt welds using automatic submerged arc welding process. Welds tend to cause imperfections in welds due to weld offsets. In order to solve the welding deviation problem, the use of focused light spot produced an indicator (see Figure), security in front of the welding head. Through two focusing convex lenses, the scattered light of the small beads will converge into a bright small spot, which directly shines on the seams of the workpiece. The operator can determine whether the welding position is adjusted in time by the position of the spot. With the different size of the workpiece, the screw can be adjusted by adjusting the distance between the focusing cylinder and the workpiece to
