Conventional technologies for welding pipe with stick or wire has been around for a long time.

There is a new technology called Solid State Fusion and FuseRing that uses no filler, one shot, flawless in less than 60 seconds. This process produces no fumes. No

particulates.

It can be scaled 2” to 48” with global applications – pipeline, refinery, nuclear, ships and submarines.

Objective of welding

Today’s technology across stick or autogenous welds have some common characteristics.

1 mm at a time.

A beginning and an end. Time and Uncertainty.

Whether Orbital, High Energy, inside or outside; we have HAZ.

Orbital GTAW, a fusion

technology that does not require

a filler; reduce fabrication costs

for ship piping systems.

Friction, High Speed Forging offers narrower HAZ, faster but with limitations – grain flow and flash.

FRIEX rotary friction weld was 1st _{introduced 1999 to automate pipeline welding.}

Brilliant insight!

Scatter because 3 samples only. Will need to test many more to find the sweet spot for each combination of material.

One part is stationary and the other half has to rotate and shear.

When you come up to a valve, an expansion joint, or a heat exchange manifold what do you do?

Conventional argument has been that we can flange or weld whatever you cannot rotate but then we are introducing 2 different types of ‘welding’ into one system.

This limitation was explicitly stated in one of the patent claims.

Particularly When joining long tubular Work

pieces, this amount of total rotation or ‘spinning’ still

introduces additional complexity and technical limitations

for many applications, as for example,

at pipeline tie-ins.

Cheng proposed an intermediary, a coupling made of the same body material as host pipeline, feeder tubes etc.

Keep both sides stable, introduce two heating paddles simultaneously, bring to hot working temperature, withdraw the paddles, rotate the coupler and squeeze. The end product is a coupler w/two independent solid state fusion done at the same time.

FuseRing opens up a whole new way of doing things.

We can lay pipeline from wellhead, thru the refinery right to ship building using Solid State Fusion. Each connection taking less than one minute, repeatable; inside and outside profiles are mirror images. We can regulate the profile to be concave, convex or flat by prepping the work face to be flat or beveled.

For tight confined space in reactors, ships or submarines we weld in crawl spaces at 6 and 9 o‘clock positions. Solid State Fusion you heat up both work faces, rotate, stick and be done.

For Refinery Construction; SMR between manifold and feeder tubes, we can reduce time and cost but increase quality.

FuseRing offers new possibilities. FuseRing could act as an intermediary that is acceptable between 2 very dissimilar materials. The work faces can have different working temperatures and forging forces.

Anytime, anywhere if you can place an Orbital welder between pipes, we can put in a Solid State Fusion machine.

Dynamic Recrystalization possibly a 3rd _{axis Time vs Temp vs Shear Rate.} Instead of 2 dimensional, we might have an envelope.

Solid State Fusion – Dynamic Recrystallization is new science. The evidence shows that this technique works. The end product is superior to anything on the market.

There are 5 SPinduction singular weld machines in the world. 1st _{Eveley International, Hamilton, Ont. Axels.}

2nd _{Federal Mogul for Daimler. Cylinder heads.} 3rd _{NOV Brazil. Off Shore HCR risers.}

4th Grant Prideco. Houston Drill Pipe body to Box Ends. 5th _{SPinduction Calgary prototype.}

FuseRing double weld does not have a prototype and I would like to ask for your advice and help in building a prototype in N America. This technique can be

scaled and w/global applications. Join me in building this new branch of manufacturing.

Thank you Paul Cheng
