Applications: The Electroweld Bi-Metal BandSaw Blade Butt Welder is designed for welding Bi-Metal Bandsaw Blades.

Electroweld Bi-Metal BandSaw Blade Butt Welder 12KVA Model:BBW-631

Weldability: Bi-Metal Bandsaw Blades - Width: 12mm-31mm, Thickness: 0.8mm-1.4mm

*Weldable Materials- Bi-Metal BandSaw Blades.

Features:

- Fast and simple welding operation saves time.

- High quality weld joints without misalignment.

- No additional solder and flux.

- Fast preparation of strip ends.

- Robust design - therefore long lasting and reliable.

- Precision control is achieved via movable jaws run on wear resistant precision ball type guides which reduce friction and ensure utmost welding accuracy.

- Clamping device adjustable to constant pressure. Clamping arrangements are by quick action clamps and the alignment is automatic and perfect which is so essential in modern production methods.

Welding Process

- The Saw Blades to be joined should be cut straight, exactly at right angles and free from burrs on special shearing attachment (optional equipment).

- Welding Current, Upsetting Pressure and Upsetting Way are set according to the blade width.

- The blade ends are rigidly clamped in special quick acting clamps provided on the machine.

- By depressing the welding lever, the welding process begins.

- The two ends are heated to forging temperatures in a few seconds and are then automatically forged (upset).

-The welding current switches off automatically.

- The job is de-clamped and the weld completed.

Process for Annealing

- The upsetting way switch lever is now turned to annealing and the job is clamped again with the extended jaw distance which comes in automatically on flipping the lever to annealing position.

- By pressing the annealing switch on which two heat positions are provided, the job is annealed in order to normalize the brittleness of the welded area.

- Depending on the type of material, the annealing process should be repeated several times if need be.

In the past, the ends of Bandsaw Blades were joined by means of overlapped brazing. Such brazing methods required a high degree of brazing skill and yet produced weak joints on account of the foreign material being introduced. In addition to. solder and flux were required. Electric Resistance Butt Welding is a modern method which not only gives a joint strength heaver to the base metal strength but is also quick and automatic, thus eliminating human error and giving a perfect and strong joint.
