AI Technical Summary
In traditional pipe circumferential welding, when the welding carriage moves to the bottom or top of the pipe, the operator needs to manually control the arc termination position, which results in large positioning errors and leads to insufficient or excessive overlap.
The tilt detection unit obtains the rotation angle of the welding torch relative to the pipe axis. The control unit sets the critical value, and the angle display unit and alarm unit remind the operator to achieve precise control of the arc termination position. When necessary, manual intervention is required to repair welding or terminate the arc.
This improves welding quality, avoids insufficient or excessive overlap due to positioning errors, and ensures the continuity and sealing of the weld.
