Electron beam welding - Import export

Due to the individual speed control, the Roots pumps of the innovative HiLobe® series offer a nominal pumping speed range of 520 - 2,100 m³/h and can be perfectly adjusted to customer-specific requirements. In general, Roots pumps need a backing pump adapted to the gas flow and which is suitable for the application in order to operate.

Rotationally symmetrical driving gears in a line producing for automotive industry are mutually connected by electron beam welding. The camera inspection carried out until was not able to assess the quality of the weld seams at the required precision. Non-contact laser measurement system Particular Challenge: As the welding seams show a high reflectivity and are located at a position hard to access, inspection is difficult, all the more so as they dispose of a width of only 500µm. Therefore it is quite a challenge for the laser measurement system. The QuellTech solution: A QuellTech Laser Scanner Q4-5 with extremely small shape factor and high resolution proved to be perfectly suited for this application. In order to suppress reflections from elements in the surroundings, a particular algorithm has been integrated. Furthermore, this laser measurement system features a particularly adapted laser wavelength and an ultrafine laser line.
