Spray Welding and Grind
What is it?
Welding (Metallizing) is a process where very fine molten particles are propelled
onto a revolving workpiece. The particles, traveling at extreme speed and
temperature impact with the base material and diffuse to form a metallurgical
bond (microweld) with the workpiece. Application systems include Plasma HVOF,
Electric Arc, and Combustion Spray. We employ Combustion Spray
systems because of the greater flexibility and proven economy
combustion provides. Our systems allow us to spray various alloys including
Stainless Steels, Aluminum Bronzes, Ceramic coatings for areas requiring high
hardness and inert properties (corrosive packings) and nylon or zinc coatings
for protection. We also provide Fusing Alloys, which are applied and then fused
into a molten state which seals all pores and produces a true metallurgically
bonded deposit. Spray welding coupled with our Universal Cylindrical
Grinder allows us to produce superior fits and surface finishes,
using high density or super hard recovery alloys.
Where is it used?
Spray Recovery provides a solution
to worn bearing seat areas that are assembled with a locational
fit (interference) and in some cases where a sliding fit is required. Low
temperature sprayed surfaces do not fare well in areas subject to shock loads
when combined with running or sliding fits. Specific alloys provide excellent
service life for seal surfaces and packing areas and our grinding
capability greatly complements these recoveries. Call us for a recommendation
with regards to your particular application.
Why Consider Spray Recoveries?
Spray Recovery and Modifications
have proven to be a cost-effective solution to repeat shaft failures. Typical
costs average 35% of shaft replacement along with improvements in
service life in many cases.
