ABSTRACT:
A wax pattern welding system and method for producing a pool of molten wax on an area of a surface of a wax component is provided. The wax pattern welding system includes a bar of heat conducting material and a heating element. The bar has a raised heating surface, which has a recessed area for retaining molten wax when the raised heating surface contacts the wax component, and a vent structure. The vent structure facilitates confining the pool of molten wax on an area of a surface of the wax component. In another embodiment, the pattern welding system includes an attachable plate of heat conducting material, which has a raised heating surface with a recessed area, and a vent structure. The attachable plate is configured to be fastened to the bar of heat conducting material.
