Description

Technical Field

[0001] The utility model relates to the technical field of weld processing equipment, in particular to weld polishing equipment. Background Art

[0002] Gas tanks and other pressure vessels are prone to weld excess height problems during the welding process. The weld excess height will cause local stress concentration in the pressure vessel, resulting in a shortened service life. In order to solve the problem of weld excess height, gas tanks and other pressure vessels usually need to use a polishing device to polish the welds on their surface after welding. Polishing the pressure vessel welds with polishing equipment can prevent environmental corrosion, eliminate weld excess height, and avoid excessive stress concentration, thereby extending the service life of gas tanks and other pressure vessels.

[0003] When the existing weld polishing equipment is in use, the installation structure of the polishing belt in the equipment is fixed, and it is not easy to control and adjust its tightness.
