What is the operation of welding electric fuse fittings?

Ningbo Lianda Plastic Pipe Co.,Ltd | Updated: Jan 21, 2019

Specific steps:

1. Measure the power supply voltage and verify that the voltage at the time the welder is working meets the requirements. Clean the power output connector to maintain good electrical conductivity.

2, the end face of the pipe should be vertical axis, the error is <5mm.

3. Measure the length or centerline of the electrofusion tube. Mark the surface of the welded tube with a score of 0.1 to 0.2 mm thick to remove the oxide layer.

4, re-dash on the pipe, the position is 1/2 pipe length from the end face. The cleaned electrofusion tube is inserted into the tube to be welded, and the outer edge of the tube is kept flush with the marking line. Install the fused clamp, and the electrofusion tube shall not be subjected to external force. The different axial degrees of the pipe and the pipe shall be less than 2%.

5, the output connector is connected to the output end of the welder and is firmly connected to the pipe terminal.

6, welding mode setting according to the welder manual requirements, the welder is adjusted to "automatic" or "manual" mode.

7. Input of welding data Input welding data automatically or manually.

8, start the welding switch, start timing; welding parameters in manual mode should be in accordance with the pipe fittings product manual.

9, natural cooling: cooling time should be in accordance with the pipe fittings product specification, no external force should be applied to the welding part during the cooling process, after the cooling is completed, the fixture is removed.
