Band Saw Butt Welder Model - MB

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.

ANNEALING ATTACHMENT

The Upsetting pressure is now turned to annealing and job again clamped properly with extended jaws distance which comes in automatically flipping the the lever to annealing position. By turning the annealing switch on which the heat position are provided the jo is annealed in order to normalize the brittleness in the welded zone. Depending on the type of material, the annealing process must be repeated several times if needed.

SHEARING ATTACHMENT

Special shearing attachment is provided on the machine itself for cutting the piece at right angles, except for model MB-3 + 4.

GRINDING ATTACHMENT

The attachment is provided for removing the burrs from the welded zone. This unit is mounted on the machine.

Bandsaw Butt Welder

  • Weight 100-500kg
  • Color Lite Green
  • Voltage 220V
  • Application Industrial Use
  • Automatic Grade Automatic
  • Power 3-5kw
  • Warrenty 1 Year

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 ProcessThe 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.

 

Annealing AttachmentThe Upsetting pressure is now turned to annealing and job again clamped properly with extended jaws distance which comes in automatically flipping the the lever to annealing position. By turning the annealing switch on which the heat position are provided the jo is annealed in order to normalize the brittleness in the welded zone. Depending on the type of material, the annealing process must be repeated several times if needed.

Shearing AttachmentSpecial shearing attachment is provided on the machine itself for cutting the piece at right angles, except for model MB-3 + 4.

Grinding AttachmentThe attachment is provided for removing the burrs from the welded zone. This unit is mounted on the machine.

Wire Butt Welder (r)

  • Voltage 220-400 V
  • Welding Type Face To Face Wire Welding
  • Frequency 50 Hz
  • Automatic Grade Automatic, manual
  • Output Current (Ampere) 0.4 To 20 Mm
  • Power Electric

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.

TransformerThe 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 155°C. This transformer is fitted in a light welded framework.

RegulatorA regulator is provided on the primary side with 8 different stages to control the current according to the requirement.

AnnealingThe same Jaws can be used for annealing with extended jaws.

Additional Facilities for annealing can be provided at extra cost.

  • Extended annealing jaws from 4" to 10"
  • Separate heat regulator for annealing with foot switch
  • Annealing time will be control automatically by providing an electronic timer.
  • Lighting lamp with flexible stand.
