Abstract
A method for modifying a gas turbine injector is disclosed herein. The method for modifying a gas turbine injector includes removing a first tubular member from the gas turbine injector, replacing the first tubular member with a second tubular member, the second tubular member having a center axis and including a circumferential lip extending radially from the center axis, aiming a laser beam at the circumferential lip so that the laser beam forms an acute angle with the center axis, and, laser welding the second tubular member to the gas turbine injector at the acute angle, the laser welding forming a resultant weld between the second tubular member and the gas turbine injector, and such that at least a portion of the circumferential lip is consumed to form at least a portion of the resultant weld.
