Technical data – BBA and BLS series

Characteristics:

• For the automatic joining of bandsaws in seconds without the need to add metal fillers.
• Highest strength and a uniform microstructure is achieved in the joint using high upsetting force.
• As an industrial machine for bandsaw manufacturers and bandsaw workshops who carry out a lot of welding.

Decisive advantages:

• Simple bandsaw preparation ready for flash butt welding by rectangular cutting of the ends.
• Perfect weld alignment by precise guidance of the welding jaws in precision ball-baring guides on hardened round bars.
• Flashing using a cam disc and adjustable geared motor.
• Upsetting produced by a pneumatic cylinder
• Welding parameters can be precisely adjusted for a consistent welding results.
• Uniform annealing zone over the entire width of bandsaw using potentiometer and time switch.
• If required automatic annealing device with closed-loop control system and measurement of annealing temperature using an optical pyrometer.
• Low maintenance and high machine service life.

Characteristics:

• For the endless welding of bandsaw up to 420 mm in width.
• Proven MIG welding of bandsaw under protective gas atmosphere using filler wire
• Favourably-priced machine specially designed for repair work.
• Welding torch can be driven either automatically using geared motor or manually by the operator.

Decisive advantages:

• Continual feeding of filler wire.
• Placing of tips for starting and stopping the torch outside of the band width (prevention of edge crates).
• Machine design includes rear stops for aligning of the bandsaw back and has a robust clamping device with fully hinged clamping arms.
• Changeable heating rail for prewarming the bandsaw before welding and for subsequent annealing of welding seam.
• Torch guide is vertically and laterally adjustable, speed can be steplessly adjusted.
• MIG welding current source for selectable welding parameters with protective gas and wire feed (gas mixture)
• Clearly arranged machine layout for easy operation by unshilled labour.
