A heating apparatus and method for pre-weld heat treating, welding and post-weld heat treating a superalloy article in a single enclosure while avoiding oxidation of the article. The enclosure is preferably equipped with a one-way valve that permits the escape of gases, but otherwise seals the enclosure to prevent the ingress of air during welding and heat treatment as a result of thermal gradients induced when the article is inductively heated. To provide access to the article and a device used to weld the article, the enclosure is equipped with gloves by which the welding device and the article can be manipulated while a nonreactive atmosphere is fully maintained within the enclosure and the article is inductively heating.

Heating apparatus for a welding operation and method therefor

A mounting apparatus including a first element is slideably connected to a second element by a joint. The joint includes first and second spaced apart walls on the first element and a third wall on the second element that is slideably disposed between the first and second walls. A biasing feature, such as a spring, is disposed between the first and second elements. Preferably, a restraining feature is used for restraining slidable movement to one degree of freedom of motion between the elements. A bore is disposed in one wall of one of the elements and is generally alignable with a conical cavity in another wall of another of the elements and a rod disposed through the bore. The rod has a conical tip with a tip conical surface for engaging a cavity conical surface of the conical cavity. The conical tip is smaller than the conical cavity in diameter so as to being able to effect the biasing movement by axial movement of the rod in the bore. The restraining feature further may include a pivoting feature for restraining slidable movement between the elements to pivoting about a pivot point of the pivoting feature and in another embodiment a linear restraining feature may be used for restraining slidable movement between the elements to linear movement. The holder may be used to hold an electrode.
