“…The dichroic mirror inside this welding head is used to direct the process light to a system of three photodiodes (position 2 in Figure 2.1). The photodiodes are part of the commercially available Laser Weld Monitor (LWM) system [10,22,23,24] developed by Jurca Optoelectronik GmbH, now part of the Precitec Group [25]. In Figure 2.10 a photo is shown of the LWM system attached to the Trumpf welding head.…”

Weight reduction is important in the automotive industry. To achieve this, Tailor Welded Blanks (TWB’s) are used. Good examples are body panels consisting of sheets which are welded together and formed into the desired shape. TWB’s are thicker at highly loaded places and thinner in other areas. In contrast to steel, aluminium TWB’s have been introduced only recently. The forming of the sheets poses high requirements on the welds. Laser welding has the potential to produce these strong, yet deformablewelds.
