Flexible Welding Enclosures®, Ultra Low Cost Welding Chambers

14W-FlexibleWeldingEnclosuresWhen welding titanium, zirconium and some stainless steel joints it is important that the welding zone is purged of oxygen to a level as low as 10 parts per million (ppm).

A flexible chamber is available from Huntingdon Fusion Techniques HFT® for a fraction of the cost of a rigid welding chamber. Flexible Welding Enclosures® provide a solution where a rigid chamber may not be economically viable or where space may be at a premium.

Luke Keane, Technical Support at HFT® said: “For many years the enormous cost of a metal enclosure prevented all but the major companies taking on work involving the fabrication of these metals. To the rescue came HFT® a decade or so ago with the introduction of these flexible welding bubbles.” Size for size, HFT®’s range of Flexible Welding Enclosures® can cost less than one tenth of a metal glove box and less than one hundredth of a vacuum system.

These enclosures provide a very fast purging time down to a few ppm of oxygen and are ideal for small production quantities of items that need total gas coverage.

Use Backing Tape™ for Perfect Weld Underbeads

13W-WeldBackingTapeWhen welding sheets, pipes, tanks and other vessels made from metals such as stainless, carbon, duplex and chrome steels, it is important to support weld roots and provide even profiles.

As an international leader and manufacturer of weld purging technology, Huntingdon Fusion Techniques HFT® have extended their range of purging products and are providing an economical Weld Backing Tape™ for the backing of welds, where purging is required but neither easily achieved nor economically viable.

Georgia Gascoyne, CEO for HFT® said: “With the use of this relatively low cost Weld Backing Tape™, welding speeds can be increased and will result in neat, clean welds that will require minimal post weld attention. The cost of the HFT® Backing Tape™ is paid for on each weld by dramatically reducing welding time and cleaning.”

Bright, Oxide Free Welds with Trailing Shields®

45W-WeldTrailingShieldsTo save expensive cleaning and pickling costs to remove oxidation and discolouration on stainless steel circumferential welding, radiused Trailing Shields® are available.

Manufactured by Huntingdon Fusion Techniques HFT®, Trailing Shields® are suitable for any diameter of tube, pipe, tank or vessel from 1”. These lightweight devices simply attach to all standard manual or automatic TIG/GTAW and Plasma/PAW welding torches.

Luke Keane, Distributor Support for HFT® said: “The Trailing Shield® is connected to the argon gas supply and it diffuses gas out evenly without turbulence through the multi layers of stainless steel mesh built into the body of the shield. At each side, removable silicone rubber side shields provide a barrier to prevent the argon escaping sideways and remaining over the weld metal. These silicon shields are a consumable and are replaceable as they become worn.

As the weld is started, it has extra argon to that amount coming through the gas cup. Then as the welding torch is moved forward, the weld remains under an argon gas shield until the metal has cooled below its oxidation temperature.”

Nylon Weld Purge Plugs for Weld Purging

01W-WeldOrbitalPurgePlugsEnsuring that your stainless steel tubes and pipes are welded without oxidation, which leads to loss of corrosion resistance, it is vital in industries such as oil and gas, nuclear, food and beverage, pharmaceutical, semiconductor and dairy that in order to achieve a perfect zero colour weld, the oxygen level must be purged down to lower than 100 ppm before and during welding.

Huntingdon Fusion Techniques HFT® are the World leading Weld Purge Specialists and have a range of Weld Purging Systems designed to achieve the perfect weld for every application.

The Pipestoppers® Division at HFT® manufactures a range of white Nylon Weld Purge Plugs™ that are clean and suitable for weld purging of tubes and pipes up to 6” diameter.

Wire plus Arc Additive Manufacturing (WAAM)

24W FlexibleWeldingEnclosuresAdditive Manufacturing itself is great for Flexible Welding Enclosures® use where parts can be manufactured by just welding thin layers of powder or liquid metal drops to each other to build ready made components, where frequently the components were made out of solid, with lots of machining and loss of material that is wasted machining it away.

Keep an Eye on your Weld Purge

06W-PurgEye300-Nano-WeldPurgeMonitorFor many years, oxygen monitors and gas analysers have been used for weld purging. These instruments have been designed and calibrated for accuracy at atmospheric oxygen level, but not for weld purging where accuracy is required when reading much lower oxygen levels.

In the 1970’s, Huntingdon Fusion Techniques HFT® invented the Weld Purge Monitor®, an essential instrument to monitor oxygen levels when welding metals such as stainless steel, titanium and nickel alloy where a high quality, non-oxidised, zero colour weld is required.

With their scientific background, HFT® have designed and manufactured the PurgEye® 300 Nano, the World’s first and only low cost, no frills, Weld Purge Monitor® that measures accurately down to 10 parts per million (ppm) on a large alpha numeric display.

Ron Sewell, Chairman for HFT® said: “The PurgEye® 300 Nano has been developed for weld purging where data logging, alarms and welder control are not necessarily required. It is small, lightweight and inexpensive. There are no knobs, no switches, no controls, making this a really simple, ‘plug and play’ monitor.”

The use of Water Soluble Weld Purge Film® for Pipe Purging

13W-SolubleWeldPurgeFilmWhen tubes and pipes of certain materials, such as stainless steel, titanium, copper-nickel and zirconium are welded together it is desirable to purge the oxygen out of the inside of the weld zone to prevent it from reacting with the hot metal and causing oxidation, porosity, discolouration and loss of corrosion resistance.

Some high integrity products available for purging the insides of pipes, include Inflatable Tube and Pipe Purging Systems: PurgElite®, QuickPurge® and HotPurge®. It is not always practical however to use such systems for one off, never to be repeated work on just a few joints of one particular size, for closing welds, for ‘T’ piece joints or for a number of other branch type joints.

To overcome this difficulty, Huntingdon Fusion Techniques HFT® provides Argweld® Weld Purge Film® kits, with water-soluble materials that can be used for open assemblies and closing welds. The film produces an impenetrable purge barrier that can easily be washed away when hydrostatically testing the pipe or just by flushing out.

Freeze Sealing for Pipe Repairs with Qwik-Freezer™

07W-Qwik-Freeze-Pipe-FreezingFreeze sealing pipes for repair or maintenance is an increasingly popular alternative to ‘hot-tapping’ and eliminates the need to shut or drain down a system for repairs and maintenance. These systems work by creating ice plugs (or ‘freeze seals’) either upstream of the repair site or on either side of an area where a pipe system needs to be maintained.

The HFT® Pipestoppers® division manufactures Qwik-Freezer™, the industry standard portable CO2 Pipe Freezing System. With thousands of kits in use around the world for over 40 years, Qwik-Freezer™ covers pipe diameters from 3/8” – 8” (9 – 200 mm).

Qwik-Freezer™ is very quick and easy to use, requires almost no set-up time and is the only CO2 Pipe Freezing System capable of freezing up to 8” pipe. Even for smaller diameter freezes, Qwik-Freezer™ produces ice plugs that are significantly more reliable and robust, capable of withstanding far more pressure than the smaller plugs that other types of systems will produce.
