1.Trim the interface of the band saw blade, clean both ends of the band saw blade.

2.manually fix and clamp the band saw blade to the welding electrode head, adjust the welding current, turn on the welding switch for welding, re clamp the band saw blade after welding, select the tempering current, turn on the tempering switch for tempering.

3.after bandsaw tempering is completed, polish the welding slag to complete the band saw blade repair process.

UNBAS50 Band saw butt welding machines with automatic annealing infra-red spectral pyrometer for bandsaws steel strips of 14 to 50 mm

It uses a manual clamping handle and a motor-driven cam mechanism, so there’s no need for an air supply or air compressor, making it very easy to use.
our butt flash is created by a motor-driven cam disc.
The machine upsetting force is generated by a precisely adjustable spring mechanism.
The annealing with temperature control voltage can be freely adjusted, and the annealing time can be set anywhere from 0 to 10 minutes.
It automatically releases pressure during the annealing process.
Depending on production needs, a water cooling system can also be installed on the main and critical welding electrodes.
