Metal powder spray welding gun: Use
method
1st-step: with oxygen acetylene flame on the work piece is heated to
300--400 degrees Celsius.
2nd-step:The nozzle and the workpiece surface distance 120~150 mm, at
same time you can put the self fluxing alloy powder evenly sprayed on
the surface of the workpiece, and then through the flame to melt, to
appear on the surface mirror, gradually moving molten position, so that
the alloy powder and the workpieces mutually cladding, dispersed to each
other to form a binding layer firmly.
3rd-step: different kinds of alloy powder used, can get the abrasion
resistance, corrosion resistance and other different properties of
strengthened layer. |

| Spray gun, if no ignition, can not
press powder valve switch, to avoid blockage . |
| Due to the powder 's particle size is
not uniform, or become damp and other factors, make the powder valve
switch failure, clogging, it should be repaired in time before be used
again . |
| Regular cleaning spray gun, in order
to avoid the gas tube holes are blocked. while cleaning pipe hole
,ejects out and clean up the control powder feeder. |
| Spray gun at the
end of work, first close the acetylene valve, and then use the oxygen
blowing internal pipeline, after liquidation shall be sprayed welding
torch and hose hanging, prevent dust and impurity invasion of spray
welding nozzle, to effect the normal use. |
| All the pipelines
of spray welding torch are not contaminated oil, to prevent oxygen meet
oil to have combustion and explosion . |
