The WELDWATCH­ER® is our com­plete solu­tion for mon­i­tor­ing indus­tri­al laser mate­r­i­al processing.

Laser mate­r­i­al pro­cess­ing emits a broad­band light, the so-called process light. Its char­ac­ter­is­tics like spec­trum and inten­si­ty cor­re­late with many prop­er­ties of the process.

The WELDWATCH­ER® cap­tures the process light. With the aid of a pho­to­elec­tric sen­sor, the process light is con­vert­ed into an elec­tri­cal sig­nal and trans­mit­ted to the WELDWATCH­ER® soft­ware. The WELDWATCH­ER® soft­ware con­verts the elec­tri­cal sig­nal into a dig­i­tal sig­nal, the process signal.

The WELDWATCH­ER® soft­ware ana­lyzes the typ­i­cal attrib­ut­es of the process light such as radi­ance, spec­tral com­po­nents, time dura­tion and sig­nal curve. The process sig­nal is then eval­u­at­ed.

The process sig­nal is com­pared with a stored ref­er­ence and eval­u­at­ed as OK or not OK dur­ing the eval­u­a­tion. If the WELDWATCH­ER® has been con­fig­ured for a spe­cif­ic appli­ca­tion, then con­clu­sions can be drawn from this eval­u­a­tion. If the process sig­nal was eval­u­at­ed as OK, for exam­ple, then the qual­i­ty of the cor­re­spond­ing weld seam is also OK. This can help with the qual­i­ty con­trol of the components.
