Hydraulic welding machine features
Jul 12, 2018

The hydraulic welding machine is mainly composed of four parts: operation platform, clamp, heating plate and milling cutter. The clamp is detachable, which improves the convenience of welding. The clamp is separated from the operating system and easy to operate. The clamp adopts double card. The structure of the sleeve is accurate and the amount of misalignment is easy to adjust.


The hydraulic welding machine adopts the hydraulic system to control the docking pressure, the pressure is accurate, and the operation is stable. At the same time, the electromagnetic valve is used to control the operation of the cylinder, and the operation is more convenient and reliable. The digital display is accurate and intuitive because its heating plate is electronically temperature controlled.


For hydraulic welding machines, the length of the heating time determines the quality of the weld; whether the temperature can be evenly transferred to the weld surface and a certain depth, maintaining the optimum welding temperature during the conversion phase. In the actual welding process, the time of the hydraulic welding machine increases as the area to be heated increases. More importantly, the energy propagated by convection and radiation decreases as the thickness of the pipe wall increases.


Therefore, it is necessary to closely cooperate with the pressure, apply a certain pressure while heating, flatten the welding surface, promote plasticization, form an ideal welding surface for heat transfer, and then reduce the heat absorption.
