The picture shows titanium anodes with Ruthenium Iridium oxide coating.
The anodes were made in Asia, but the problem of breaking welds after the anodes were installed into the product returns and the service costs of replacing them became a big problem.
We offered to weld the 800 pieces inside a purge chamber with our patented triple HF pulse weld technique which breaks through the coating.
The coating interruption was not ideal but was found to give no problem in the further usage.
After welding, no more welds are broken and service costs reduced to zero, problem solved.
