What is the selection process for the Filler Wire in mold and die applications?
Filler Wire Size: The size of the wire is measured by the diameter or thickness of the filler wire. The selection process of the filler wire size depends on a couple of different variables. These parameters include (1) the mold area that will be repaired and (2) the actual amount of material needed to build up the specified repair area. The diameter of the filler wire varies from as thin of 0.003 [in] to as thick of 0.020 [in]. The laser energy is minimized when using smaller diameter wires and therefore reduces heat input into the material. This allows the lowest possible heat distortion of the repair area for customers who require it. When the repair area is relatively larger than it requires the use of a larger wire to make sure the repair area is properly filled.
Filler Wire Type: Choosing the correct filler wire type requires an analysis of specific parameters of the repair job. These parameters include (1) the hardness requirements of the metal, (2) the type of mold material, (3) analyzing what specifically caused the damage, and (4) what condition is the repair area in. By answering these 4 parameters, you can properly choose the correct filler wire type for your mold repair applications.
