Alternative: Stud-Welding

Increased productivity and flexibility for the installation of pipe, tube, hose and cable clamps

In many areas, stud welding is considered to be the most economic fastening method for components and is sometimes even the only technically feasible solution. Because the stud is joined with the substructure over the entire surface of the stud without any hollow areas, a high strength of the joint can be achieved.

Stauff is now using this proven principle for the installation of pipe, tube, hose and cable clamps in the Standard Series (according to DIN 3015, part 1) with M6 mounting thread, where female threaded weld studs replace the regular weld plates; distance plates made from plastic provide the necessary spacing between the clamp bodies and the substructure. If required, the system can also be adopted for alternative fastening methods, e.g. for clamping belts, cable ties or corrugated cable protection hoses.

In addition to the individual components – weld studs, distance plates, clamp bodies and metal hardware required – the company also provides the correspondingly designed assembly tools such as the weld inverter and the weld gun with tripod, weld stud retainer and distance adaptor. The lightweight and compact weld inverter works without high-voltage current.

Thanks to increased productivity and flexibility for the installation of clamps, the system offers considerable savings potentials for users with significant processing volumes, especially when working in horizontal or overhead position. The amount of rework on welding locations can be significantly decreased, and material distortion is reduced to a minimum through low thermal stress.

The joint of the weld stud with the substructure impresses in particular with a high degree of strength and safety, which is at least at the same level as for regular weld plates.

Background Information

For more than 50 years now, the STAUFF Group with headquarters in Werdohl (Germany) has been successful in the development, manufacturing and distribution of pipework equipment and hydraulic components for mechanical and plant engineering as well as for service and industrial maintenance. The overall product range currently includes about 33,000 standard products as well as numerous special and system solutions according to customer requirements or based on own developments.

Wholly-owned manufacturing, sales and service facilities with more than 1,150 employees in 18 countries and a tight network of authorised distributors and representatives in all major industrial regions of the world ensure high presence and service paired with a maximum of availability.

In April 2015, VOSWINKEL was acquired and became a member of the STAUFF Group. With two sites located in Meinerzhagen (Germany) and 230 employees, VOSWINKEL is considered to be one of the world's five largest producers of quick release couplings for hydraulic systems. The long-established company also develops and produces a comprehensive range of hydraulic hose fittings – particularly for high-pressure applications – as well as custom-designed piping, primarily for construction and agricultural machinery as well as for commercial vehicles.

In 2015, the companies of the STAUFF Group have generated external sales revenue totalling EUR 230 Mio.
