Post-welding treatment process for steel structural profile steel

Abstract

The invention relates to a post-welding treatment process for steel structural profile steel. Post-welding treatment equipment comprises a workbench, a fixing device and a grinding device, wherein thefixing device is fixedly arranged at the upper end of the workbench, and the grinding device is arranged at the lower end of the fixing device; and the fixing device comprises fixing plates, screw rods, supporting plates, positioning plates, connecting plates and rotating rods, and the grinding device comprises right-angle frames, grinding heads I, fixing blocks, threaded rods, movable plates andgrinding heads II. According to the post-welding treatment process for the steel structural profile steel, multiple pieces of welded angle steel are fixed at the same time through the fixing device,and therefore the friction force between the angle steel and the positioning plates is increased through rubber plates with rough surfaces, so that the angle steel is further positioned; and the surfaces of ground angle steel are cleaned while the welding positions of the angle steel is completely ground through the grinding device, so that the purpose of preventing excessive debris accumulation from affecting the grinding quality is achieved.

Description

technical field [0001] The invention relates to the field of steel structure processing, in particular to a process for post-welding steel structure section steel. Background technique [0002] During the welding process of metal objects, the local high-temperature melting of metal solder joints is caused by the passing of electric current. When the liquid metal solidifies, it is easy to form tiny bumps under the action of metal flow under its own weight. The appearance of the weld, and there are often defects such as lack of penetration under the weld bead, which is likely to cause stress concentration. Since the surface of the steel structure is easily corroded during use, it is necessary to perform surface treatment on the angle steel weld. [0003] In the process of grinding the welded section steel, due to the structural limitations of the section steel, the following problems exist in the actual operation process: [0004] (1) When the traditional section steel weldin...

AI Technical Summary

Problems solved by technology

[0004] (1) When the traditional section steel welding post-processing equipment grinds the welded section steel, due to the structure of the section steel, it is difficult to completely polish the surface of the section steel weld. Other processing increases the processing cost

[0005] (2) When the traditional section steel welding post-processing equipment grinds the welded section steel, due to the welding work requirements, the welding place of the section steel often needs to be welded for one week, so it is often used for grinding in stages, and multiple positioning is required, which is easy lead to lower work efficiency
