WELDING PROCESS : On pilot Butt Welding Equipment, the saw blade or wire ends are cut straight, exactly at right angles and free of burrs,on special shearing attachment available. Welding current, upsetting pressure and upsetting way are set according to the blade width, the blade ends being rigidly clamped by special quick acting clamps provided on the machine. By depressing the welding lever the automatic welding cycle begins. The two ends are heated up to forging temperature in a few seconds and then automatically forged (upset). At this instant, the welding current switches off automatically. The job is declamped and the weld completed.

ANNEALING ATTACHMENT : The upsetting way switch lever is now turned to annealing and the job is again clamped securely with extended jaw distance which comes in automatically flipping the lever to anneaiing positiofl. By pressing the annealing switch on which two heat positions are provided, the job is annealed, in order to normalize the brittleness in the welded zone. Depending upon the type of material, the annealing process must be repeated several times if need be.

PRECISION WELDING : Minute precision control is ensured by the use of latest control devices The moveable jaws run on precision ball type guides which reduce friction to almost nothing and ensure utmost welding accuracy.

SHEARING ATTACHMENT : Special shears with arrangements for mounting on the front of the machine are available as an accessory.

GRINDING ATTACHMENT : Grinding Attachment is available as an accessory, mounted on the top of the machine, and is necessary for removing the
welding fiash.

RESEARCH & EXPERIENCE : Much research has gone into perfecting these Butt Welding Machines to give optimum performance.
