Twin Lap Welders
Applications:
The TwinLap is a high speed joining process. It is the welder of choice for Galvanizing, Annealing, Silicon, Anneal & Pickle, Coil Build-Up and Coil Preparation lines. The weld passes through Temper Mills and Tension Leveling equipment without releasing pressure on the strip! When minimal weld over thickness is required, and the strip thickness is ≤3.5mm for full hard materials (4.0mm for soft material), the TwinLap is the best solution.
Mechanical Features:
- Rugged “O” frame
- Durable “Oil Bath” welding heads with quick-change weld wheel feature
- High precision pneumatic or hydraulic dual re-squaring shear with four sided cutting blades
- Urethane clamp inserts to prevent strip slippage and separation
- Precision linear motion control of welding carriage
- Automatic scrap removal
Electrical Features:
- AC, DC of MFDC welding current
- Automatic weld parameter set-up with “upper level” computer communication
- Laser edge sensor weld initiation to prevent strip edge and weld wheel damage
- Constant current weld control for consistently high weld quality
- All types of PLC available – Siemens, Allen-Bradley, GE Fanuc and others
- Close-coupled secondary bus bar and welding electrodes – highest current density of any seam welder and lower energy usage
Benefits:
- Forgiving welding process compared to Laser and other joining processes
- Skilled Trade personnel do not need extensive training
- No need to release tension in your mill to pass the weld – creates a “rollable” weld
- Less concern about weld breaks
- Lower capital investment compared to a Laser welder
Fast cycle time – typically less than 60 seconds for the
