Our standard longitudinal seamers are available as either external or internal/flat sheet models. They are specifically designed for making 100% penetration, single pass welds on cylinders and flat sheets while minimizing or eliminating heat distortion to the material.
Through a unique engineering design, buildup of magnetism is minimized which reduces or eliminates arc blow.
Pandjiris®‘ standard external seamers are cantilevered from one end to allow loading and unloading of cylinders and other closed sections requiring a longitudinal seam. Pandjiris seamers provide exceptional visibility around the weld head and work area. Typical seamers are used to perform butt welds, but with slight modifications, certain corner joints and lap welds can also be welded efficiently such as cones and bowed shapes.
Pandjiris® has designed a quick-change rocking back up bar. This patented design minimizes down time when changing back up bars. It is ideal for situations where seamers are run continuously, different materials are being welded, or in applications where materials of different thicknesses are being welded.
