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.
Note:
1. medium pressure type structure, it must be used in the medium pressure
acetylene generator and an acetylene cylinder pipe, absolutely should not
be used in low pressure acetylene generator and pipeline.
2.Spray gun, if no ignition, can not press powder valve switch, to avoid blockage.
3 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 .
4. attention --must use dry powder.
5. 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.
6. keep the gas pipeline drying, smooth to avoid damp effect of powder.
7.all the pipelines of spray welding torch are not contaminated oil, to
prevent oxygen meet oil to have combustion and explosion .
8. 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.9. the use of spray welding torch, oxygen, acetylene pipeline must be
equipped with a backfire preventing device.
