Working with Palladium

Contamination

Contamination

When contaminated platinum is being stressed through rolling, drawing or hammering, it will crack and become unusable

 

Possible causes of contamination during soldering or welding:

  • Using carbon soldering surface (charcoal)
  • Abrasive rolled into the Pt surface during fabrication
  • Filings from other precious or non-precious metals.
  • Using flux or Fire coat on Pt during high temperature operation
  • Using steel tweezers near the soldering flame
  • Oil, grease or soap used during drawing, rolling or general working

 

Tips to avoid contamination:

  • Use only oxidizing flames, avoid redusing flames during soldering or welding
  • Avoid trapping contaminants in the Pt during cold working
  • Dedicate files, sanding sticks and bench pins to platinum
  • Do not weld or solder with acetylene / oxygen flames
  • Use only Natural gas / Oxygen, Propane / Oxygen of Hydrogen / Oxygen
  • When using a water torch, disable the flux feature

 

Tips on what not to do:

  • Don’t use Acetylene Gas. Only Natural Gas, Hydrogen or Propane will work with Platinum
  • Don’t weld without eye protection. UV radiation WILL damage your eyes
  • Don’t weld when stones are nearby. The welding process will damage most stones
  • Don’t use your soldering pick or steel stweezers near the flame, as they may contaminate the platinum
  • Don’t weld on a charcoal block. Platinum and Carbon do not get along.
