Ribbed square tubes and the welding of ribbed square tubes: As the products to be welded are hollow square pipe and have coating, four welding transformers are required.
Welding speed requirements: No less than 40 pieces per hour. Drawing on accumulated technical experience and catering to customer demands, our company puts forward targeted solutions applicable to this
Industry Special Machine. We adopt gantry welding principle and apply high-power, high-energy welding current to meet efficiency standards.
Welding and material arrangement can be realized by specially designing double-feed welding molds.
This
Automatic Welding Machine consists primarily of gantry frame body, medium frequency inversion constant current welding power source, electrical control system, dedicated welding pressure cylinder, upper and lower electrode assembly, dual-mold rack, water cooling system, pneumatic system, monitoring unit and safety mechanism, with detailed specifications stated as follows:
Machine body: It adopts vertical reinforced structure fabricated from premium thick steel plates, fitted with rationally arranged stiffeners and completed with stress relief treatment.
MF inversion DC welding power source is assembled with transformer, controller, inverter, power driver, rectifier, capacitor board, IGBT and central control modules. It converts original 50/60Hz input voltage into 1000Hz, and the rectifier diode in transformer secondary loop converts power into constant current output. This design greatly elevates secondary circuit reactance coefficient, effectively solving previous energy loss issues and optimizing constant current welding loop to cut manufacturing expenses. Equipped with stable power bearing capacity suitable for
Automatic Type operation, it boasts prominent merits over traditional welding power supplies:
A) Energy conservation;
B) Higher power factor and lower production cost;
C) Less interference in large-opening secondary circuit and stable welding current; welding performance remains unaffected even when inductive magnetic materials exist in secondary winding;
D) Balanced load distribution for power supply equipment, supported by three-phase power supply and energy storage design.
| Advantages | Save energy |
| Improve the power factor and reduce production costs; |
| In the secondary circuit with large opening area, interference can be reduced and welding current is constant current. When the secondary winding has inductive materials (with magnetic property), it will not affect the welding |
| make a balance of the loading of power supply device, medium frequency inversion constant current welding power source uses three-phase power and stores energy |
