Tigama A15 triple deoxidised, copper coated TIG filler wire for the joining of carbon steel, ideal for root runs in pipework and thick walled material, the rods may also be used without flux for oxy-acetylene welding.
Contains Zirconium, Titanium, and Aluminum for purer weld deposit, in addition to Silicon and Manganese.
Typical materials to be welded include S255N-S380N, P235GH-P265GH, P295GH P355GH.
Applications include repair on mild and low alloy steel, small diameter pipe and tubing, root pass pipe welding and sheet metal applications.
Produces x-ray quality welds over most surface conditions.
Predominantly used during the TIG welding process,welding current DC- with a shielding gas of Argon at 7-10 l/min.
