Weld Seam Detection & Positioning in
Tube Benders & Hydroforming Presses:
Weld seam detection in tubes with magnetic flux leakage or eddy current is necessary
in pipe and tube benders , or in hydroforming presses when cnc tube bending automotive
automotive components. such as exhaust manifolds, head rests, side members, roll bars,
or engine cradles. The tube manipulation process involves not only pipe and tube bending
but also tube cutting, tube forming, tube punching, tube end forming, and tube notching.
Other applications are the detection and elimination of welds after coil joining in decoilers,
blanking presses, or cut-to-length lines thus enabling the use of lower cost welded coils.
A related application is the detection of weld seams in wires and rods and cable connections
in the extrusion process.
The new high performance sensor NS24 is capable of detecting weld seams in thick walled
ERW-tubes for positioning the weld inbetween the ultasonic probes for nondestructive testing.
A special application of weld seam location is the positioning of 55 gallon drums or
similar containers for silk screen printing purposes.
