Tejindra Electric Works (Regd.) - Welding Machinery

STERCO Forced Air Cooled A.C Arc welders are being used since 40 years as power source for most of manual metal arc welding jobs, required in Rolling Mills, Cement, Plants, Thermal Power Projects, Shipyards and all type of heavy and medium industries.

it is specially designed for Butt welding of ferrous and non ferrous wires from 0.3 mm to 2.5 mm to withstand subsequent drawing. This machine is a table model and easy in operation.

WELDING PROCESS:

This Micro Butt Welder is automatic upset Butt Welding machine. The welding current and the initial upset gap are 10 set according to the size of wire, the upsetting pressure being preset. The ends of wires to be clamped by special quick acting clamps to correct alignment of the wire ends. By pressing a push button, the welding cycle is initiated and completed automatically by built in controls. The job is now declamped and annealed if necessary, in the provided annealing device.

Sterco Butt Welding machines are designed and developed with outstanding dependability, exceptional accuracy for butt joining of wires/rods of mild steel, carbon steel, steel alloy copper, aluminium and brass etc. bringing together under pressure the ends of the parts to be welded and by applying short circuit current to the joints. The jaws of the machines are arranged in such a way so as to make possible the welding of wires over a considerably wide range of diameters of specially shaped cross section. Mechanical timer is provided in which it is automatically tripped, after the job is done. The welded joint can withstand high tensile, and can be drawn upto minimum size.

TRANSFORMER

The transformer of the machines is of special type, conforming to international standard specifications primary and secondary are of solid electrolytic copper of ample section, suitable for withstanding continuously temperature of 155C. This transformer is fitted in a light welded framework.

It is designed to meet the needs of heavy type of jobs like: Rolling Mills, Sugar Mills. Shipyards, Maintenance of Machinery and all type of heavy fabricaion.

The set consists of a Heavy Duty transformer housed and secured by means of nuts and bolts in a heavy gauge steel plate tank with heavily wounded Primary and Secondary coils submerged in oil to provide cooling. The current is controlled by means of Air Gap between Primary & Secondary Coil.

The Sterco Arc welding transformers are manufactured in accordance with IS : 1851 (1997) specifications and mounted on three Cast Iron / Rubber wheels with front wheel swiveling and steerable by means of draw bar.

Note:We reserve the right to change the design and modify specifications at the discretion of our technical department.

This above machine is also available in Double Operator Model-EC (D/O).Technical specifications of each transformer of Double Operator Arc Welder will be as per Model-EC.

Sterco Band Saw Butt Welder is the result of many years of experience, research and development. It is the most modern method of joining Band Saw Blades giving a joint strength 25% higher than that of the base metal strength. It eliminates the old process of overlapped brazing. Resistance welding is quick and automatic, thus eliminating human error and giving a perfect and strong joint.

WELDING PROCESS

The Band Saw Blades are cut straight exactly at right angles and free of burrs. Welding current, upsetting pressure and upsetting way are set according to the blade width the blade ends being rigidly clamped by special quick acting jaws. By Depressing the welding lever the automatic welding cycle starts. The two ends are heated upto forging temperature in a few seconds, then automatically forged (upset) and current switches off.

We are known for delivering the orders within the specified time frame owing to our modern transit facilities. Ours is a reckoned name in this domain and actively involved in offering quality-centralized product range that is designed and developed using the qualitative raw material.
