Abstract
A process for the assembly of wax trees in which a wax runner is placed in a flat position and a wax pattern is located adjacent the wax runner. Both the wax runner pattern and the wax runner are heated and then are placed in contact with one another where heated. Then the wax pattern and the wax runner are separated slightly to form a fillet weld between the wax pattern and the wax runner. An apparatus is also provided which, by robotics, brings a multiplicity of wax patterns to a wax runner and which automatically heats both the wax patterns and the wax runner before simultaneously pressing both the wax pattern and the wax runner together. Once a wax tree assembly is completed a new wax runner replaces the wax runner that has been formed into a wax tree and additional wax runners are affixed in the same manner.
