Steel wire skeleton composite pipe welding method

Wire skeleton composite pipe welding method mainly has the following steps: welding part processing, welding parameter setting, welding operation, welding quality inspection, post-processing.

1, welding part processing: remove the welding part of the dirt and oil, to ensure that the welding part of the clean. If there is rust or oxidized layer on the welding part, you can use emery cloth to polish it in order to increase the affinity of the welding part.

2, welding parameter setting: according to the material and thickness of the steel wire skeleton composite pipe, set the appropriate welding parameters, such as current, voltage, welding speed.

3, welding operation: the steel wire skeleton composite pipe is fixed on the working table to keep it horizontal. Adjust the welding electrode to the appropriate distance and angle, so that it is in contact with the welding part of the composite pipe. After energized, the welding electrode will generate heat to melt the welding part. During the welding process, the welding speed should be kept stable to avoid welding quality problems caused by too fast or too slow speed.

4, welding quality inspection: after welding is completed, the welding quality check. Check whether there is welding cracking, porosity, inclusions and other defects. If there is any problem, it needs to be repaired or reworked in time.

5, post-processing: after the completion of welding, the steel wire skeleton composite pipe for post-processing, such as weld polishing, anticorrosion treatment, etc., in order to improve the service life of the pipeline and the appearance of quality.
