Abstract (en)

[origin: WO0181037A1] Products for aiding welding or high temperature cuttingoperations comprise a workpiece marker and a welding or cuttingaid system. The marker includes a luminescent material which isexcited by UV radiation generated during arc welding to emitlight in the visible spectrum, e.g. orange light. The aidsystem includes a light filter matched to the visible emissionwavelength of the marker interposed in the light path, e.g.adjacent the dark filter of a welder's mask. The marker is usedto mark a weld or cutting path trace visible to the welderduring the operation. A method of aiding a welding or cuttingoperation using the marker and matched light filter is also provided.
