A welding training system includes one or more welding operator device which provides positional feedback relevant to a quality weld. The positional feedback is analyzed and, when the positional feedback is outside of a predetermined range, a signal is provided to the welding operator. In one embodiment, tactile feedback is provided in a welding gun.

Welding training system

Disclosed is a method for controlling a welding apparatus (1) or a power source (2), whereby an operator can set different welding parameters, such as welding current, welding rod diameter, welding method, etc. by means of an input and/or output device (22). The set welding parameters are supplied to a control device (4). Subsequently, the welding apparatus (1) or the power source (2) are controlled by the control device (4) according to the pre-set welding parameters. The operator can select a surface or a cross section of a weld seam, especially a fillet weld, before, during and/or after the welding process has been started by means of the input and/or output device (22). The control device (4) interrogates the set values for additional parameters especially stored in a storage device to form the weld seam and/or set or indicated for the welding process.

A system and a method for tracking and analyzing welding activity. Dynamic spatial properties of a welding tool are sensed during a welding process producing a weld. The sensed dynamic spatial properties are tracked over time and the tracked dynamic spatial properties are captured as tracked data during the welding process. The tracked data is analyzed to determine performance characteristics of a welder performing the welding process and quality characteristics of a weld produced by the welding process. The performance characteristics and the quality characteristics may be subsequently reviewed.
