Stainless Steel Hopper and Cold Welding Process

Carefully cold welding a customers stainless steel hopper assembly to be used in the farming and collection of fruits and vegetables.

Cold welding or contact welding is a solid-state welding process in which joining takes place without fusion/heating at the interface of the two parts to be welded.

Unlike the fusion-welding processes, no liquid or molten phase is present in the joint. Cold welding was first recognized as a general materials phenomenon in the 1940s. It was then discovered that two clean, flat surfaces of similar metal would strongly adhere if brought into contact under vacuum. Newly discovered micro-[1] and nano-scale cold welding[2] has already shown great potential in the latest nanofabrication processes.
