Jewelers Toy Store: Laser Welding Tips and Techniques

Frank McAllister, CEO of a well known Mining company studied the quantity of a jewelry that was made from 950 palladium has surpassed the same for platinum products. He calculated the number of ounces that was used globally for each alloy.

If you will going to use a laser welding to the 950 palladium you need to make sure that it was setup properly. Laser welding's equipment settings and technical procedure might differ to platinum. The three most requested bench tasks that was used for a successful laser welding of 950 palladium products are:

1. Filling voids and pits

2. Minor assembly

3. Ring sizing

Research was conducted to do some testing for them to be able to use the laser welding perfectly specially for a 950 palladium. It is very important that the settings of the laser machine are correct and equipment should be maintain properly to avoid any bad effect for the final outcome. For us to explain clearly, we will going to explain how those bench tasks works.

Filling Voids and Pits

During the casting process with jewelries alloy most often result to voids and pits. By using laser welding you can hit the void several times to open and shape it. The tip of the wire was held in direct contact with the palladium piece, within the void and a pulse of energy melted 950 palladium from the wire into the void. Each void was overfilled with 950 palladium and then filed even with the surface of the ring for finishing. Make sure that when filling voids and pits using a laser you should start by directly to the void. On this way, it will melt the bottom and will expose fresh metal from which to build upon.

Minor Assembly

For minor assembly the most effective way is to tack the parts using a laser welder followed by soldering to complete the process.

Ring Sizing

It is not always safe to resize a palladium using a torch because gemstones are heat sensitive. Because of that we need to set the equipment properly to avoid the metal become brittle.

Experts continuously do some research about the best options for using a laser welder. But, as of now it is much easier to follow those procedures to avoid breaking the metals that you have.
