Weld Seam Tracking in Submerged Arc Welding Systems via 2D/3D Profile Sensors

In the steel industry, the so-called submerged arc welding process is used for material thicknesses of over six millimeters. In order to accurately guide the welding torch installed on a linear axis, the joint must be precisely measured. A 2D/3D profile sensor with cooling module and protective screen installed in front of the welding head determines the contour of the joint with micrometer precision, even at high temperatures. A special software module enables easy parameterization of the sensor and ensures constant determination of the guide point – even with different types of joint.

2D/3D Profile Sensors

Sensors of this type measure profiles of objects such as weld seams or glue beads and check roundness or gaps using laser triangulation. Red or blue laser light, open interfaces and various performance classes are available.
