Abstract:  
TO CREATE STRUCTURAL COMPONENTS for boom cranes, steel manufacturers need the capability to process one-inch steel coil. Residual stresses present in thick steel coil are due to the larger amounts of constraining material. When the coil is leveled and laser cut into parts, material under residual stress can become unconstrained and warp. Warped steel parts cannot be sold and will damage laser cutting equipment. The manufacturing process was analyzed to locate the cause of residual stresses and investigate residual stress testing methods.
