E The hot melt welding machine is used to convert the current 50/60Hz electric frequency into 20KHz or 40KHz high frequency electric energy according to a transistor action machine

Manually lift the workpiece onto the bracket → clamp the workpiece with three jaws → jack up the tailstock cylinder → lower the welding gun in place → fine tune the angle position

The models and parameters of products produced by each manufacturer are different, so the latest automatic electrothermal welding machine that supports both manual and barcode shou

1. Mechanical device The spot welding machine system is composed of mechanical device, power supply device and control device. In order to meet the requirements of welding process,

1. Use roller bar or bracket to level the pipe, adjust the concentricity, use clamps to correct the out of roundness of the pipe, and leave welding space. 2. Check and adjust that

1. The welding power supply shall have static and external characteristics. Only in this way can the stability of the arc be maintained and the welding quality be guaranteed. 2. We

1) Defects of weld joint forming. In general, the defects in the forming of welded junction mainly lie in the deviation of crimping geometry and structure, which cannot meet the re

In the process of hot melt welding of PE pipes, it is necessary to comprehensively control their quality, carry out management work for operators, mechanical equipment, welding mat

1. Do not knock off the coating after welding, so as to slow down the cooling of the weld bead. After the weld bead cools down, knock off the coating and clean the weld bead. 2. Im
