Roll Bonded Clad Metals - Spur Industries - Roll Bonded ...

Roll bonding, also known as roll welding (ROW), is a unique welding process. Two or more metals are guided through a set of rollers that produce extreme pressure. As a result, a metallurgical bond occurs and a new material is formed by the two metals. The high pressure and reduction in thickness produces a uniform bond that is stronger than the ...

Bonding Metal Substrates | 3M

Improve aesthetics – the bonding process does not distort or discolor the substrates. Enable the use of thinner substrates – because the metal is not distorted a thinner substrate may be just as strong. Lower energy costs – thermal bonding is very energy-intensive. Improve worker comfort – most adhesives can be applied at room temperature.

Cold Rolling – Process Overview - Matmatch

Multi-stand mills have three to six pairs of rollers in a series, each pre-set to reduce the thickness by a certain percentage until the final thickness is reached. Usually each pass will reduce the thickness between 50 to 90%. Due to the high compression forces and friction, the temperature of each pass has the potential to reach as high as ...
