Spraywelder™ System Demonstration

Back by popular demand, UK Technical Manager Warren Lewis demonstrates the #Spraywelder™. Designed to produce a consistent coating for circular parts, the Spraywelder™ is ideal for seal areas on shafts, motor body shafts, and glass industry parts such as narrow neck press, blow plungers, and plugs.

Warren takes us through the process of applying powder to a plug using the Spraywelder™. Learn how to achieve a consistent deposit with step-by-step instructions.

Watch the video to hear more about the history, advantages, and applications of Spraywelder™.

Hi Mr. Lewis very nice videos. I have been coating with the D3 to the J3 Spraywelder systems for over 40 years and use Wall Colmonoy fusion bonded alloy exclusively. The only thing I would add as a safety issue is wearing a certified face mask to prevent inhalation of particles. As you know most of the Colmonoy materials are nickel based, as well as cobalt based, and both can be very toxic!! Protection and safety are key!

Hallo Mr. Lewis, congratulations for your excellent videos. I would like to ask you at what distance and what rpm you are using when you are adding powder on an turning axle. Thank you in advance. S.Kopitsas Athens Greece.

Generally the blow and blow plungers are about 10 to 15 millimetres, and it is very difficult to coat those small diameter s with the spray welder( there will be a lot of over spray and while fusing the fusing torch heat will be too high for the b&b plug diameter), I think that is why the fuse welder is used commonly thorough out the glass industry

Do you offer spray service or just the equipment?

Why acetylene rather than LPG?LPG should burn hotter than acetylene from my memory. Can it be used with lpg oxy?

Came here from a YouTube channel called Abom79, where an industrial manual machinist called Adam Booth went over full time to pursue his YouTube channel further.

He uses the Eutectic Terodyn 2000 spray welding system which although similar to yours does not have the final fusion stage using the acetylene torch for a long period. He uses this system on bearing surfaces and highlights its benefit of much lower temperatures ( compared to welding as the alternative) thus not altering the base metal temper and avoiding shaft distortions and the like. Your system having to use the acetylene torch at the final stage would seem to put itself at a disadvantage wrt that.


The system he uses has been around for many decades. and although it might have decreased in popularity over the years ( probably due to comebacks), he swears by it provided preparation and consistency is good and it's used for the right application. He says he has done loads of these at his previous employ, without any failure comebacks.

Good day...what kind of powder will recommend for Cast Iron?

This is great, for sure, but it is unfortunate that they named it a “Spray Welder”, as this often confuses and leads people to believe this is a welding process. It is actually the flame spray powder process, which is great and widely used for >100 years. Because of this name, when helping clients and students, I need to continuously enforce that “Spray Welding”, a generic term that many people use to describe thermal spray, is not welding and the unfused coating is not welded to the substrate. If secondary fusing is used, then the coating is bonded to the surface more like welding, but not the same as welding and there is a gigantic heat affected zone due to the glowing hot fusing temperature needed. Again…all great! Just remember that this is thermal spray and not welding.

What you need to run that gun air oxygen and propane?
