Weld backing tape

HUNTINGDON Fusion Techniques now manufactures three grades of weld backing tape, suitable for different weld current levels.

A light duty grade for welding up to 80A, a medium current version for welding up to 160A and a heavy duty grade for welding up to 240A.

According to the company, the tapes can be used with any arc welding process and can be carried out by operatives with lower skill levels.

Suitable for automatic and manual welding techniques, the amount of weld root grinding and cleaning is said to be minimised.

The ABT0004 – Light duty tape – is available in pre-cut 25m lengths, rolled up and delivered in multi lingual labelled boxes, complete with user instructions. The light duty backing tape with its weave thickness of 1mm will aid in the production of a flat weld underbead with minimum oxidation and porosity.

Typical customers are pipework fabricators for the dairy, brewery and pharmaceutical industries. Using flat sheet metal, as well as cylindrical structures nominally up to 1.6mm thick.

The ABT0005 – Medium duty tape – is suitable for medium duty fabrication using flat sheet metal, as well as cylindrical structures nominally up to 2.4mm thick, pipework fabricators for the pharmaceutical and petrochemical industry, and vessel manufacturers.

The ABT0006 – Heavy duty tape is suitable for heavy duty welding applications, such as submerged arc welding of plate in the shipbuilding and ship repair industries. Also for use with boilers, heat exchangers and pipelines.
