There are three styles of AC flash welders:
- Cam-actuated flashing and upset
- Cam-actuated flashing with hydraulic upset
- Hydraulic servo controlled flashing and upset
AC flash welders are used to weld many types of materials where smooth, clean joint surfaces are not critical. The flashing produces the process heat for welding.
The modular design of the brake shoe welder enables welding of brake shoe webs and rims. There are three modules:
- Bending and welding
- Part transfer (robot or hard automation)
- Calibration (rolling or impact)
The brake shoe welder has quick tool change for fast changeovers and an inverter power source for DC welding. Rim and web magazines hold a buffer of parts. Machine sizes include:
- A1 – Brake shoe diameters from 100-180 mm (car, single web)
- A2 – Brake shoe diameters from 170 to 390 mm (car, single web)
- A3 – Brake shoe diameters from 250 to 480 mm (truck, double web)
- Clean process, minimal machine cleaning
- No flashing, burnoff – material savings
- Less noise than AC flash welding
- Reduced power cost due to 3-phase input
- Better end alignment due to smaller initial and final die openings
- Very low smoke output during welding
- High speed scalable system for 300, 600, or 900 parts per hour
- Patented assembly system produces rim/disk assemblies with low runouts
- Manual and high speed automatic systems options available
- Welding heads feature multi-torch configurations for all disc and rim attachment styles
- Torch maintenance can occur without shutting down entire system
The DC Butt Welding System combines multiple machines to provide a complete welding solution, such as:
- Cut-to-length equipment
- ID stamp of the strip
- Stacking/Destacking
- Coiling
The weld post process including trimming, edge trimming, planishing, and rerounding of the band. This low-smoke emission process uses DC butt welding for fast, clean, accurate welding and utilizes a high-speed system that produces up to 1,200 parts per hour.
