Weld backing tape suitable for up to 240 amps
Huntingdon Fusion Techniques Ltd. has published a four-page leaflet about its Argweld® weld backing tape. Three different grades of tape are available for welding up to 240 amps.
The tape is placed at the back side of a weld, eliminating the need to manufacture backing bars and manipulate them in tight spaces. The weld is cast flat onto the glass fiber weave, eliminating drop-through and icicles. Postweld dressing and cleaning are reduced, and slag and massive oxidation are eliminated.
