Socket welding for high-tech gas cylinders - Handling and welding robots work “arm in arm”

Valve sockets are a key element of gas cylinders: they enable secure and gas-tight connection of regulators and fittings to the cylinder. At ALUGAS, around 1,000 sockets are welded every day – and as of recently the work is now fully automated. For this purpose, system builder Roland Ruegenberg based in Bad Sobernheim designed a system centred around two MOTOMAN industrial robots by Yaskawa. These literally work “arm in arm”, taking care of both the entire parts handling and the welding process.

ALUGAS wants nothing less than to “make life easier” for its customers. And they mean it quite literally, too: campers and barbecue chefs swear by the company’s pressurised containers for liquefied gases such as propane and butane (LPG), as do forklift drivers and tradespeople. This is because the high-tech gas cylinders from Bad Sobernheim are up to 50 per cent lighter than conventional steel cylinders, making them ideal for mobile use – whether at work or in the sports and leisure sector.
