Metallurgically
bonded overlays can be easily made on small and large parts such as dies,
valves and instruments with the use of manual or automatic plasma powder
feeding systems. Using a powder feeder that functions by having Argon carry
a controlled amount of powder alloy into an Argon/Hydrogen shielded, plasma
transferred arc column results in a precise deposit of filler alloy with
minimal dilution of the base metal.
Manual and machine models are available. The torches are
water cooled and can be used up to 30 amps 100% duty cycle. Torches include
a special PWT shield gas cup. Accessory kits are sold separately.
Feed rates under 2 gm/min at gas flows under 2 SCFH. High
degree of repeatability and can deliver up to 9 lb/hr at low gas flows.
Panel mounted digital display to monitor powder feed back pressure. Hopper
will hold apprx. 5-6 lbs. of metal powder. Manual adjusted precision gas
flow meters are easily adjusted. Remote ON/OFF pendants supplied. |
