Introduction :

Seam Welding Machines 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.

WELDING TRANSFORMER:
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 ‘F’ insulated, impregnated and tropicalized suitable for withstanding the continuous temperature of 140º C.

CURRENT CONTROL:
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.

COOLING SYSTEM:
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.

ELECTRODE :
Circular disc type top and bottom Welding Electrodes.

ELECTRODE CONTROL SYSTEM:
The upper electrode is actuated by hand lever to provide electrode force.

ELECTRONIC CONTROLS:
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.

• A squeeze time control to select the delay between initiation of the foot switch and the start of the weld. Timing is adjustable from 2-25 cycles, continuous
• Synchronous (digital) timing control of 1-9 cycles “ON” and 0-9 cycles “OFF” both in steps of one cycles each.
• Heat control circuit based on the phase shifted firing of thyristors which enable continuous adjustment of current between 10% to 100% of then value available from welding transformer.
• High power switches device consisting of 2 Thyristors connected in inverse parallel mounted on water-cooled heatsinks. The sizes of the thyristors are chosen to watch the KVA of the transformer and the devices are of ample capacity to withstand momentary overloads. Protection devices for high voltage surges and a thermos with (for inhibiting the operation if the temperature of the thyristor pad rises above a preset limit) are incorporated.
• Hold time to provide a delay between stoppage of weld and separation of electrode wheels. The range of adjustment is 1-9.

Product Details:

Seam welding is a welding technique in which the two similar or dissimilar metals are connected by supplying an electric current and in this process a nugget formation takes place. Mostly, these nuggets are formed in the form of butt or the overlapping welding components. Do you know the meaning of this nuggets? Well, the nuggets are nothing but the small pools of the molten metal which are formed at the location with a high electrical resistance. Seam welding is one of the types of Resistance welding.

Adavantages 

Resistance seam welding has the advantage of creating clear welds with no gas formation or welding fume. There is also no need to use filler materials to make the join, which can be made to be both gas and liquid tight, offering a number of applications.

The process can be fully automated, making it a highly repeatable process. In addition, resistance seam welding can create both a single seam weld and a parallel seam weld at the same time.

Disadvantages

While resistance seam welding is fine for producing joins in a straight line, the rollers cannot produce more complex curved welds. Welding is also not possible at internal corners or where other component features obstruct access for the wheel electrodes.

This process is also unsuitable for joining sheets of metal of over 3mm in thickness. Due to the speed of the roller, a highly skilled operator may be required to ensure the quality of the weld, while the welding machinery is also expensive.

Features:

• Fan cooled transformer having core of high grade silicon steel.

• Thyristor controlled electronic timer with electronic heat control, to give heavy duty high speed operation, providing smooth, stepless and accurate adjustment of welding current.

• High quality roller bearings carrying the roller shafts, guaranteed longer-life of the roller heads.

• Minimum wear of the electrode wheels due to efficient cooling system.

• Study drive shafts ensure nonslip drive.

• Leak proof joints at much lower costs, than conventional welding.

• The main frame of the machine is of the heavy rigidly reinforced and robust welded steel constriction.
