Weld Seam Detection in steel strips of a coil winding machine for automotive safety belt retractors.

This application demonstrates the detection of overlapping weld seams of spring steel strips. 

In this process it can happen that the weld seam stops inside the encircling coil. Even in this case we offer best possible weld seam detection.

Product

• SND40 Flat
  SND40 offers the highest possible flexibility in the detection of joints.
• NS9N-AAD-SC + XA100
  NS9N-AAD-SC - The autarchic weld seam sensor for narrow metal strips up to 30 mm (1.18 in) of width, preferably for magnetizable steels or stainless steels.

To ensure a safe processing, during manufacturing of the muffler, the right positioning of the weld seam is crucial.

Product

• SND40 Round
  In combination with the suitable sensor, the SND40 can be used for detecting longitudinal weld seams, for all metals.

During the manufacturing of gas tubes, some welded tube connections can occur. These need to be detected, to be removed from the material.

Product

• UFD40
  With an encircling coil sensor combined with the UFD40, the tube connections can be easily found and separated.

Weld Seam Detection during the processing of tube ends for automotive catalytic converters. 

A special feature of this application is the vertical position of the catalytic converter tubing and the horizontal movement of the sensor NS9S.

Product

• SND40 Round
  In combination with the suitable sensor, the SND40 can be used for detecting longitudinal weld seams, for all metals.

The material which is brought into the press line often comes as an endless welded coil. To make sure, that there are no weld seams in the end product, there needs to be a weld seam detection station.

Product

• SND40 Flat
  SND40 offers the highest possible flexibility in the detection of joints.

The weld seam of a coil must not be in the final product, so the position of the weld seam needs to be detected.

  SND40 offers the highest possible flexibility in the detection of joints.

During the production of automotive components, the metal forming is an elementary process step. Experience shows that automated testing has become indispensable in order to fulfill high quality expectations of the automobile industry for the components.

Forming processes such as a bending, pressing or hydraulic forming may cause cracks, particularly if the structure of the semi-finished material is not completely normalized. A good example is offered by welded tubes. 
An automated monitoring can help, as the function of components with the presence of cracks is drastically affected and leads to a reduced life span.

No supplier can afford the recall of thousands of components and certainly not regarding the inevitable damage to customer relationships.

Product

• UFD40
  Makes crack tests of the components possible using the eddy current principle. The surface of the critical points is monitored thereby by one or more eddy current probes.

Structure testing for the inspection of retaining rings according to DIN471. It is checked whether the parts are hardened or not.

Not hardened parts are sorted out.

Product

• I20 hardening control
  Noncontact dual head hardening control

While tube bending it is crucial to know the position of the weld seam, so it won’t come to cracks and breaks in the material.

Product

• SND40 Round
  In combination with the suitable sensor, the SND40 can be used for detecting longitudinal weld seams, for all metals.

Tube bending line consisting of a tube loader with weld seam detection and positioning, a robot loader and a separate tube bending machine.

The tubes are processed in a hydroforming press to rear axles. 

The exact position of the weld is required to ensure the stability of the rear axles.
