Thanks for the response. Being new to this I had set myself up with check sheets so I didn't forget something I made notes on everything. I think I need to perfect the connections.
We came across another issue today which I hope you can shed some light on.
We tried to anodize a new part with a section of weld around the diameter , all including the weld had been polished to a mirror finish so no weld could be seen. After being in the desmutt we noticed the mirror finish had turned a bit "milky", the mirror finish had gone. The item is a circle with a few holes protruding from the outer edge. I used 2 of these to hold the part so I had 2 rods connecting to the tank bar. Half way through the anodize time I noticed patches of discoloration around the protruding holes including the holes which were not held. My air bubbles were directly below the part.
After closer inspection these areas are now brass colour
They follow the same pattern on both sides of the circle. The weld now shows and it looks really bad.
Any ideas ??
Thanks
