LPKF TMG 3

A new transmission tester for inline and offline laser welding operations has been launched by LPKF. The LPKF TMG 3 transmission tester quickly determines the transmission properties of welding partners, ensuring that faults are detected earlier in the processing chain.

During transmission laser welding, the laser beam passes through the upper, laser-transmissive joining partner to pass its welding energy on to the underlying, laser-absorbing joining partner. A moderate joining pressure aids thermal transmission, and produces a clean and reliable weld seam.
