Friction Welding - The fast and versatile welding solution

How does friction welding work?

Commonly used with steel structures, friction welding is the process of generating heat through mechanical friction between a moving work piece and a stationary component. Our approach is to distinguish between the friction phase and the forging phase. During the friction phase a rotating work piece is pressed against a fixed one, then once both have been heated to a sufficient temperature the forging phase begins whereby the rotating work piece is stopped and a force is applied to continue pressing the two pieces together.

What are the advantages?

In addition to super fast joining times, friction welding techniques are generally melt-free thereby offering an optimum welding method for modern production operations. In fact, for many types of assembly friction welding is recommended over other methods for both metallurgical and commercial reasons.

Another key advantage of friction welding is the ability to securely joindissimilar metals – often impossible with other welding methods due to the different melting points of the metals. Welded connections between stainless steel, reinforcing bars or other steel components are essential in civil and structural engineering works; friction welding provides a cost-effective and fast solution for such jobs.

A friction-welded joint is a butt- type, full-contact welded joint that achieves a fusion between the two materials at the joint interface with no gaps. Only a very weak electrochemical reaction is possible at this point, which virtually eliminates the risk of galvanic corrosion, in turn providing cost benefits over time by eliminating the need for expensive repair work.

Furthermore, the heating of the two materials is uniform over the entire contact face, ensuring the same strength properties can be assumed throughout the plane of the joint.

Dealing with dynamic stresses

Friction-welded joints between stainless steel and ribbed reinforcing bars are subject to dynamic stresses. Following extensive testing and countless years of practical experience, particularly in transport infrastructure projects, it has been proven that friction welding is the ideal method for dealing with dynamic stresses. For further proof of this, we have carried out fatigue tests with 2.5, 5 and 10 million load cycles. In the subsequent tensile tests it was always the ribbed reinforcing bar that failed.

If any further evidence was required, thanks to its great versatility and many advantages friction welding has been specified in the framework development planning of Deutsche Bahn AG and confirmed as a production method for the Federal Ministry of Transport’s building and urban development for transport infrastructure projects.

Stud Welding

The fast, reliable and accurate welding solution

How does stud welding work?

A type of spot welding, stud welding is a fast and highly effective process whereby a stud is welded onto a second piece of metal in a single, one-sided operation. It works by generating an electrical arc between the stud and the other component which then fuses the two together. Once the welding time has expired, the end of the studying is immersed in a weld pool before the welding current is switched off. The weld pool then solidifies in a matter of seconds to form a strong, secure bond.

What are the advantages?

Stud welding enables us to quickly and efficiently attach threaded bars, sleeves, studs etc. in diameters from 6mm to 19mm to other components. No fuss, no hassle, just a fast, accurate and leak and tamper proof solution.

Mechanical Machining

Further to providing extensive welding services, we can also carry out the following customary mechanical machining processes on our premises: Sawing / Drilling / Cutting / Internal/External Threading (up to size M/Rd 52) / Pressing (up to 600t) / Bending / Punching / Stamping.

Your guarantee of quality

We pride ourselves on delivering a service you can always trust. Here are just a few of the ways we achieve this:

  • Quality Management System accredited to DIN ISO 9001:2008
  • Specific incoming goods inspections
  • Constant in-house monitoring of production
  • Constant monitoring of parameters for friction welding, with automatic termination in the event of a deviation from the given value according to process tests
  • Stationary testing machines with up to 1200kN tensile force
  • Mobile testing machine with up to 300kN tensile forces for onsite tests.
