摘要： The gas metal arc welding process of the present invention extends the axial spray metal transfer range with a non rotating arc from 10 to 25 Ibs/hr using an electrode wire diameter between .035 to .052 inches. The process is carried out by maintaining an electrode extension of between 3/4 to 1 1/4 inches with a three component shielding gas mixture consisting essentially of argon and oxygen in combination with carbon dioxide or carbon monoxide in a volume proportion of oxygen 1-2%, carbon dioxide 8-15%, balance argon. The arc voltage is maintained in a range of between 29 and 40 volts.

摘要： A method (100) of welding a superalloy component (10) includes the following sequential steps. A welding step (110) for welding a cavity (12) using a filler metal (14) in an inert atmosphere, where the cavity (12) is located in the component. A covering step (120) for covering the filler metal (14) and a portion of the component with a weld filler layer (18) in the inert atmosphere. The weld filler layer (18) has a greater ductility than material comprising the component and/or material comprising the filler metal (14). A second covering step (130) for covering the weld filler layer (18) with a braze material (20), and subsequently performing a brazing operation. A heat treating step (140) heat treats the component.

摘要： A method of controlling a weld penetration profile on a workpiece (306) having an outer region and an inner region is described. The method comprises the step of applying energy to the outer region of the workpiece with a welder (302) to produce a weld pool (304). The method also comprises the steps of penetrating the workpiece (306) such that the weld pool (304) spans between the outer region and inner region, and also applying a shielding gas to the inner region at a pressure that provides a force that limits weld penetration. A corresponding apparatus is also defined.
