Flame spraying

November 06, 2020

Flame spraying is one of the oldest forms of thermal spray. Typically using oxygen and acetylene, these thermal spray systems melt wire or powder in the combustion stream and apply it to the part. These coatings are great for restoration of old parts. Flame spraying systems can spray I.D. and O.D. components and can be readily brought to a customer site for repairs if needed.
