Weld Seam Detection at Tubes
SND40 | Add-On: RSB |

The Weld Seam Detection in tubes is a difficult subject because of the many variables involved:

  • the welding method
  • the type of material used: regular mild steel, highly alloyed steel, magnetic or nonmagnetic stainless steel and, of course, all types of high-strength steels being used primarily in the automotive industry
  • the wall thickness of the tube, e.g. magnetic flux leakage methods are limited by the depths of their wall thickness penetration
  • the type of treatment that the welded tube received, e.g. annealing or coating
That is the reason why ROLAND ELECTRONIC has developed the proven system SND40 for maximum flexibility in Weld Seam Detection.

SND40

SND40 offers a maximum of flexibility in Weld Seam Detection. The great benefit lies in the combination of magnetic flux leakage and eddy current technology; the customer can process all sort of metals and can expect even at cold drawn or heat treated materials a remarkable reliability.
 
The system is able to process tube diameters from 5 to 1000 mm (0.19 to 39.37 in) at a wall thickness up to 12.5 mm (0.49 in).

Applications

The SND40 system is the first PC based system of its kind. It combines the strengths of analog sensor principles with digital signal analysis for the purpose of weld seam detection. For many years tried and proven magnetic leakage flux sensors and new types of eddy current probes make the SND40 a highly flexible weld seam detection system.
