Delivery time of products for satellite payloads is increasingly becoming a key competitive factor for companies in the relevant industry sector. This paper discusses a new approach of joining standard waveguide segments such as flanges, bends and straight segments. With the combination of using both a pulsed laser system and wire freed drive along with a special holding mechanism, a complex aluminum waveguide for the Ku band was welded. Measurement showed that the electrical performance exceeds the requirements.
