Operation
The SURFOX machine works by an electrochemical process
to clean and passivate welds on stainless steel. SURFOX
electrolyte solutions are phosphoric acid based, approved
for food industry, and are activated by an electrical cur-
rent to clean welds. The process takes only a few seconds
without damaging or scratching the surface of the parts to
be cleaned.
Your SURFOX machine can clean:
u
TIG welds
u
Plasma welds
u
Laser welds
u
Spot welds
u
MIG welds (with Pulse technology)
Basics of passivation:
u
The cleaning of the welds is not only for aesthetic
purposes but most importantly for passivation.
u
Passivation is the treatment of stainless steel surfaces
to remove contaminants and promote the formation of
a thick and durable protective chromium oxyde layer.
u
This passive layer will insure the corrosion resistance of
stainless steel.
u
If passivation is not done properly, stainless steel and
heat affected zones may start to rust.
