Precitec, Gaggenau, Germany, is now offering a new complete solution for wire-guided joining processes. The “Scansonic ALO3” is a brazing/welding head with a fully integrated coaxial quality monitoring system. The system requires no additional space and gives users the cutting-edge performance of Precitec products. Seam geometry monitoring detects the profile and the position of the fillet welds on the lap joint and double-flanged seams on the butt joint.
Fixture mechanisms can be optimally matched to the welding results, irrespective of any additional quality monitoring components. The welding head causes no obstruction whatsoever in the processing area and can easily travel in and out between the fixture mechanisms. Profile measurement takes place a few millimetres behind the welding spot, necessitating only a minimal overrun at the seam end.
Frequent weld defects like lack of fusion, wire on the upper/lower metal surface, gaps between the metal sheets, etc., can now be reliably identified and monitored. The system also recognises open pores from 0.5 mm upwards. Existing systems can easily be retrofitted.
