Arc welding seam calibration

Seam calibration

In arc welding it is common use that the detection and measuring for calibration of the welding seam is done through a large variety of methods, provided by the different robot manufacturers and system integrators.

The arc welding technology package includes a number of these methods that have a set of standard, generic parameters up to manufacturer specific extensions.

The following calibration methods are available:

	Touch sensing with wire Determination of the workpiece by touching (i.e. collision) between the welding gun wire and the workpiece. Calibration of the welding seam is done before starting the welding process.
	Touch sensing with nozzle Determination of the workpiece by touching (i.e. collision) between the welding gun nozzle and the workpiece. Calibration of the welding seam is done before starting the welding process.
	Seam search with point laser Determination of the workpiece by measuring the workpiece position with a laser. Calibration of the workpiece position is done before starting the welding process.
	Seam finding with laser Determination of the workpiece by measuring, i.e. scanning the start and end position of the welding seam with a 2D/3D line laser. Calibration of the welding seam is done before starting the welding process.
	Seam tracking with laser Determination of the workpiece by measuring the workpiece Determination of the workpiece by continuous measuring the workpiece position during the welding operation with a line laser.
