What are the factors that affect the quality of the fused connection interface?

Ningbo Lianda Plastic Pipe Co.,Ltd | Updated: Dec 17, 2018

1. Influence of voltage fluctuation on interface quality

The resistance value of the resistance wire in a given electrofusion tube is constant. Therefore, the heating power of the resistance wire depends on the voltage supplied by the power source, so the quality of the welding port may be deteriorated due to the influence of voltage fluctuation on the heating power.

2. The influence of welding time on the interface

The range of heat required for each size of the electrofusion tube is fixed. Too much or too little heat will have a fatal effect on the quality of the weld. Under the premise that the welding voltage and the resistance of the tube are fixed, the welding time is the fitting. The determinant of calorific value, so the welding time should be accurately controlled.

3. Influence of ambient temperature on interface quality

The change of the ambient temperature during the welding process directly affects the heat transfer conditions of the welding zone, which in turn affects the quality of the welding. Therefore, the welding machine can monitor the ambient temperature and automatically adjust the output parameters according to the deviation results.

4, the impact of bad operation on the quality of the fusion interface

The so-called bad operation, on the one hand, refers to the scraping or cleaning of the pipe when welding does not meet the specifications (the socket is not in place, the end of the socket has a large slope, etc.), which requires the operator to have certain welding knowledge. On the other hand, the error that occurs when the welding parameters are input, this should be avoided by the setting of the welding machine itself.
