Abstract
A welding system includes at least one high intensity energy source to create a weld puddle during a root pass on a narrow joint of a workpiece with a clad layer. The system also includes a controller to control a weld ramp out process such that, as the molten puddle advances to a start of an existing root pass weld, the controller at least one of decreases an energy output of the at least one high intensity energy source and reduces an interaction time between the at least one high intensity energy source and the weld puddle. After completion of the root pass, a thickness of a root pass weld in a region that is at or near the start point of the existing root pass weld is in a range of 100 percent to 130 percent of a nominal root pass thickness of a remainder of the root pass weld.
