AI Technical Summary
Traditional steel cylinder welding methods suffer from poor welding uniformity and insufficient operational safety. In particular, during manual operation, the cylinders are not securely fixed and rotate unevenly, affecting welding quality and airtightness, and lacking closed protection.
The top of the cylinder is fixed with a cylinder top clamp and its position is adjusted on the guide rail by a slide block. After the top of the cylinder is connected to the cylinder body, it is fixed with an expansion clamp. The rotary motor drives the expansion clamp to rotate at a constant speed for circumferential welding.
This method achieves uniform welding between the top of the cylinder and the body, improving welding quality and safety, and preventing injury to operators.
