Abstract
A method for determining distortion of a member which results from the member being subjected to a welding operation is disclosed. The method includes the steps of (1) locating the member so that the member assumes a first position, (2) obtaining first data measurements of the member while the member is located in the first position, (3) performing the welding operation on the member whereby the member distorts and assumes a second position, (4) obtaining second data measurements of the member while the member is located in the second position, and (5) calculating distortion of the member based on the first data measurements and the second data measurements. An apparatus for determining distortion of a member which results from the member being subjected to a welding operation is also disclosed.
