Application of Solid-state High Frequency Welding Machine in High Frequency Welded Pipe Production

Solid-state high-frequency welding machine in addition to the whole working voltage is low, while the channel capacitance and wear in the welded steel tube on the induction loop directly resonant, because no welding change, less a coupling, the efficiency was higher, then the induction coil (V-shaped opening) of the gap can be appropriately reduced, is to improve the efficiency of welding one of the factors. High-frequency welding machine is different from the tube-type high-frequency welding machine, tube-type high-frequency welder welding output transformer, induction loop installed in the secondary side of the welding, easier to match, the induction coil requirements are not very strict, But more than one welding coupling, the efficiency was significantly lower. One thing is certain, the induction coil strict and standardized production of the benefits generated by the induction loop is much higher than the production costs.

The remote operation and power adjustment of the solid-state high-frequency welding machine are realized. The LCD display is equipped with the armature voltage, excitation voltage indication and DC voltage and DC current indication of the DC converter cabinet. Can choose to install speed - power closed-loop control. Depending on the type and quantity of DC converter cabinet, there are design differences.

More than two laps (including two) induction coil, need to wear PTFE tube to reduce the unnecessary ignition phenomenon. Two circles of copper tape in the induction loop to be wrapped with PTFE tape, and then around the non-alkali belt, and then dipped in insulating paint or resin drying after drying. Induction loop must be matched with the device can produce good results, or come to naught. To correct the traditional habit of using the induction coil with the tube device, in order to achieve the best effect of solid-state high-frequency energy-saving, in addition to using solid-state high-frequency equipment, select the matching induction loop is also critical.

Through further understanding of solid-state high-frequency steel pipe welding machine for straight seam welded steel pipe welding mechanism and the basis of mechanical adjustment, can be found in solid-state high-frequency welding machine for welding of straight seam welded steel pipe, the crew of mechanical and electrical cooperation is particularly important. As long as the accumulation of experience in the production, welding, mechanical, induction coil material selection and shape with many adjustments to the best condition, in order to make the whole production line to play a higher efficiency, resulting in greater economic benefits.
