Longitudinal Seam Welding Machine
LONGITUDINAL SEAM WELDING MACHINE Offered in 50 to 200 KVA capacity, available in longitudinal/circumferential and universal versions. Precision built, sturdy design and robust construction suitable for high production and uninterrupted service in the manufacturing of drums, barrels, silence, fuel tanks, transformer radiator, water heater auto rims, etc.
These machines are always made to specific customer requirement with highly sophisticated leak proof joints.
Construction :The main frame of the machine is of heavy rigidly reinforced robust welded steel construction. It combines a compact streamlined appearance with maximum resistance to mechanical deflection. The welding transformer is enclosed in the main frame and is easily accessible, for inspection.
The transformer of a special type, water cooled, having the core of high-grade electrical steel, primary and secondary coils of solid electrolytic copper of ample section, heavy duty class insulated, impregnated and tropicalized suitable for withstanding the continuous temperature of 140º C.
Transformer primary coils provided with taps brought out to tap change links for adjustment for welding current in a 6 step from 50 to 100%. Tap change links are enclosed behind machine door and are easily accessible for variation of welding heat.
Transformer, secondary connections, arms and electrode wheels are water cooled. Internet water cooling piping with the flow adjusting values for each circuit and discharge to an open drain pot for visual observation of flow are provided in the machine.
Circular disc type top and bottom Welding Electrodes.
ELECTRODE CONTROL SYSTEM:
The upper electrode is actuated by hand lever to provide electrode force.
Seam Welders are provided with solid-state electronic controls housed in a well-designed sheet steel cabinet. The standard design of the cabinet is suitable for mounting it on the sidewall of the machine; floor mounting shall also be provided a request. The control knobs and panel are elegantly arranged, provided maximum convenience to the operator. The front panel is protected from misuse by providing a transparent guard door. All internal wiring is easily accessible for servicing. The circuit design is versatile enough for almost all type of requirements and consists of the following facilities.
