Weld Backing Tape

Argweld Weld Backing Tape, is used specifically for supporting weld roots and to provide very even weld root profiles.

The Weld Backing Tape™ comprises a 75 mm wide aluminium adhesive tape that has a 25 mm wide fibre glass band in the centre onto which the weld can be cast. Alternate to Ceramic Weld Backing.

 

Description

Increases Welding Speeds

Welding speeds can be dramatically increased with the help of Argweld® Weld Backing Tape™.  The resulting weld is neat, clean and requires minimal post weld attention.Typically for the welding of thin wall stainless steel sheet and vessels from one side only, the backing tape can be attached to the backside of the weld, to support the weld pool, keep the argon from the weld torch surrounding the weld pool and eliminating the need to back purge, while giving a consistent high quality under bead profile. It is now possible to make welds from one side only, where double sided welding used to be applied. This eliminates the need for expensive weld preparations and the need for back gouging. Because weld roots are flat and clean when using , post weld dressing and cleaning costs are dramatically reduced.

Backing Tape Reduces Welding Costs

Using Weld Tape will significantly reduce linear and circumferential seam welding costs, as it  allows faster welding speeds and greater production rates while producing smooth profile and flat, clean weld under beads. For purging large vessels, the tremendous savings of purge gas and waiting time pays for the use of the backing tape many times over. The cost of tape is paid for on each weld and additional cost savings are achieved through increased welding speed and reduced weld cleaning. Where large volumes are filled with expensive inert gas to prevent oxidised welds, the use of backing tape allows welders to complete the work quickly without the cost of inert gas and lengthy waiting times for purging.Argweld® Weld Backing Tape and Argweld Weld Purge Tape™ are available for immediate delivery.Argweld® Weld Backing Tape is a glass fibre weld backing system for supporting the weld pool, casting a smooth, flat weld bead free of icicles or drop through. This protects the weld root from the formation of heavy oxidation.By using the Argweld® Weld Backing Tape™, no back gouging or back grinding process will be required. The tape will trap the argon or other shield gas from the weld torch to hold the gas surrounding the weldpool, effectively providing a back purge facility and keeping the weld free from heavy oxidation. In the case of vessels, tanks, containers etc, Argweld® Weld Backing Tape™eliminates the need to back purge the whole vessel, while giving a consistent high quality underbead profile.Using Argweld® Weld Backing Tape™, it is possible to weld with MIG, (GMAW), MMA (GMAW), TIG (GTAW) or plasma (PAW) processes for the joining of all metals including stainless, duplex, chrome and nickel steels.With Argweld® Weld Backing Tape™ welds can be made faster, thereby increasing production rate and reducing manufacturing costs. The support of the molten weld pool allows excellent side wall fusion thus helping to eliminate weld defects. Post-weld cleaning and grinding labour costs are dramatically reduced because oxidation is prevented by the enclosure of the weld during its heating and cooling phases.In cases of welding large diameter pipes or vessels, there will be a massive purge gas savings by using backing tape instead of filling complete pipes or vessels.Argweld® Weld Backing Tape™ can be used for horizontal or vertical welding and results are so successful that there is rarely need for re-welding or re-work. The tape will not change the chemistry or metallurgy of the weld.The Argweld® Weld Backing Tape™ can be used for welding sheet, plate, pipes, vessels, tanks, silos, heat exchangers, cryogenic, pressure and vacuum vessels and hundreds of other applications made from metals such as : Carbon Steel, Aluminum, Stainless Steel, Duplex Steels, Chrome Steels, Copper Nickel, Cast iron, Nickel alloys and Cobalt alloys.Industries using Argweld® Weld Backing Tape™ include large pipework, sheet and plate fabricators as well as shipbuilding, ship repair, heating, cooling, HVAC, agricultural machinery, food, dairy, breweries pharmaceutical, petrochemical, and many others.
