The metal casting process is applied and results in two metal substructures.
Spot Weld Join
The two halves are spot welded together to secure their relational position.
Investment Support
An investment material is mixed and then formed around the metal cast.
Soldering Jig
A jig will fully secure and support the structure during the soldering process. This is then fired in a kiln to harden the investment and also to remove any moisture.
Heat and Flux applied
Taken from the kiln still hot, a gas torch is used to apply localized heat to the area to be soldered.
Solder applied
Once the correct temperature is reached solder is fed into the joint.
Solder Flows
The heat from the gas torch keeps the solder flowing, and is removed only when the technician is confident that no voids, air pockets or gaps exist.
Cooled and Sand Blasted
The newly joined metal substructure is then allowed to cool before it is sand blasted to remove the surrounding investment material.
