Friction welding technology key to drastically increased chain wear life

World Cement,


Austrian premium chain manufacturer pewag will present its newly developed pewag hero friction-welded chain at the AICCE 2015, which will take place in Cairo/Egypt from 10 – 12 November. This innovation marks the starting point of a new era in chain manufacturing.

30% longer lifespan

pewag is the first chain manufacturer worldwide to have taken up the innovative technology of friction welding and refined it for the manufacture of the next generation of chains. Unlike conventional round steel chains, only forged components are used to manufacture the pewag hero. This means that the chain links have a particularly convenient shape with additional wear volume.

"The innovative pewag hero friction-welded chain achieves a 30% longer lifespan compared to a conventional round steel chain", says Christoph Spyridon Voutsinas, Sales Director Hoist and Conveyor Chains at pewag. "This means that the wear-related replacement intervals are significantly prolonged and associated costs drastically lowered."

A new era of chain welding

Friction welding is a tried-and-tested joining technology that has been used by aviation and automotive industries for decades. In friction welding, heat is generated through mechanical friction between the links to be joined, which causes the material to plasticise. A defined lateral force is applied to fuse the components to a whole chain link with precise pitch and strand lengths. Christoph Spyridon Voutsinas: "With pewag hero, the future of chain welding starts now."

Background

pewag has been working in the manufacturing of chains and components for centuries. Since the original forge in Brückl was first mentioned in an official document in 1479, the pewag group has developed into one of the global leaders in chain manufacturing.
