The IR beam provided by the laser radiation source SK 1100 is guided through a highly flexible IR optical fiber, coiled onto a cable drum.
The IR beam head, for effective illumination of the welding area, is very compact (outer diameter 12 mm) and has already seen exemplary service in numerous welding applications, including pipe-welding repair in nuclear power facilities (with orbital heads for external and internal pipe welding).
A fully flexible reinforcement protects the optical fiber without constraining the mobility of the welder.
The compact video camera has a specially developed lens head of small diameter. Auxiliary control of aperture or focus is unnecessary and the internals are protected when the system is exposed to extremes in environment or heat.
The objective unit is fully equipped with a close-up lens, aperture adjustment and filters, all protected behind resilient safety glass. This protective glass shield, as well as that on the illumination head, must be changed regularly to ensure the consistent quality of the imaging.
