A. Sheet to sheet, plate to plate, pressure vessels, large diameter pipes and tanks, longitudinal and circumferential seams, to support the weld pool. Weld Backing Tape can be used anywhere where a back purge is desired but not possible or too expensive with gas.

Backing Tape

Q.  What metals can be welded with Argweld® Weld Backing Tape®?

A. All weldable metals including carbon and stainless steels, duplex steels, alloy steels plus copper, nickel, titanium and cobalt alloys.

Q. What welding processes can I use with Argweld® Weld Backing Tape®?

A. TIG/GTAW, FCAW and MIG/GMAW. The constraints are the current. 80 amps for the lightweight grade, 160 amps for the medium grade, 240 Amps for the heavy-duty grade and 600 amps for the extra heavy-duty grade.
