Heat treatment to anneal residual stresses during additive manufacturing
Abstract
An additive manufacturing system having a heat source for melting powder particles in a desired shape and pattern to produce a product. A secondary heat source is used for heat treating the product to achieve heat treatment. The secondary heat source is used to peen or anneal residual stresses caused by the additive manufacturing process.
