Today we will learn about what is forging and types of forging. Basically there are 3 types/ methods/ or processes of forgings. In t 405 0 obj<>stream Comparison: Stainless Steel, Aluminum Alloy, Copper, Copper Alloy, Carbon, and Alloy Steel Forging Processes Forging Process differs for various grades, types and alloy of metals. Forging is normally used in components where safety is fundamental, for instance, in planes, cars, tractors, boats, oil drilling equipment, motors and other industrial machinery. Roll forging In this process, the bar stock is reduced in cross-section or undergoes change in cross-section when it is passed through apair of grooved rolls made of die steel. The system was implemented in an industrial forging process of a forked type forging, which resulted in the tool life being The blows are delivered with a hammer (often a power hammer) or a die. 386 0 obj <> endobj PPT ON FORGING 1.
