Description

Technical Field

[0002] A weld seam is the joint formed after welding. Based on the cross-sectional shape of the weld seam itself, welds are categorized as butt welds and fillet welds. To inspect weld quality and ensure aesthetics, welds are polished after welding. Due to varying requirements across industries, the special equipment industry, in particular, places extremely high demands on weld quality.

[0003] In the existing technology, most weld grinding is done manually. Due to the uneven force of manual grinding, uneven wear and tear such as tiny grooves will appear on the surface after grinding, which may be the source of cracks or corrosion, affecting the service life of such equipment and posing a safety hazard. At the same time, in order to prevent corrosion of special equipment during use, the user will apply anti-rust paint on the surface of the equipment. According to the requirements of regular inspection of pressure vessels, the welds must be polished during regular inspections of the equipment. Manual grinding cannot control the force well, which will lead to uneven wear of the equipment body. At the same time, due to the space limitations of the installation location, manual grinding is sometimes impossible. Therefore, the existing technology lacks a device for uniformly grinding welds.
