Butt weld structure for angle iron tower steel cladding

The utility model provides an angle iron tower steel-clad butt weld structure which comprises angle iron, a butt weld is arranged on the angle iron, a first groove is formed in the inner side face of the butt weld, a first welding layer is filled in the first groove, a second groove is formed in the outer side face of the butt weld, and a second welding layer is filled in the second groove. The depth of the second groove extends from the outer side face to the center of the thickness of the first welding layer, and the second groove is filled with a plurality of welding layers. According to the utility model, the one-time inspection qualification rate of the steel-clad first-grade welding seam of the angle steel tower is improved to 99%, and no defect position exists during nondestructive testing. 本实用新型提出了一种角铁塔包钢的对接焊缝结构，包括角钢，角钢上设置有对接焊缝，对接焊缝的内侧面设置有第一坡口，第一坡口处填充有第一焊层，对接焊缝的外侧面设置有第二坡口，第二坡口的深度从外侧面延伸至第一焊层厚度的中心处，第二坡口内填充有若干道焊层。本实用新型使角钢塔包钢一级焊缝一次交验合格率提高到了99％，无损检测时无缺欠位置存在。
