Professional Bench/Welding Technologies
Manufacturing a Crown Using
Tack- & Pulse-Arc Welding Technology
Knowing how to tack-, fusion- and pulse-arc-weld at the bench saves time, increases quality and drives profits up for your shop and service department
David and Diana Howard, owners of My Jeweler Inc., Albuquerque, NM, recently worked with a local church to design and manufacture a crown to be placed on a popular church icon painting. The churchs parishioners donated jewelry to the cause. David Howard sent the old gold out for refining and received over 4 ounces of fine gold in return. He alloyed the gold to 14k yellow, poured ingots and rolled wire for the crown. The crown has over 600 contact joints, so he used tack- and pulse-arc-welding technology. Heres an overview of the procedures he used:

Important: Tack-, fusion- and pulse-arc equipment settings will differ and are based on the volume, amount of contact and alloy of the material you are working with. Practicing using like materials will give you a parameter for the settings required for your application. Keep a record of settings and tasks for future reference.
