Oerlikon Tenacito 65R description: Basic coated MMA electrode for reliable, crack-free and tough welded joints on steels with a yield strength <555 MPa. The weld metal is of extremely high metallurgical purity, is ageing-resistant, retaining good CVN toughness to -60C and CTOD tested. Very low hydrogen content. Due to the double coating of the 2.5 mm and 3.2 mm sizes, the arc is both stable and concentrated, even at lower welding currents when positional welding, with good gap bridging characteristics. Welds are of X-ray quality. For sour gas applications, the nickel content is restricted to <1.0% max. On request, TENACITO 65R can be supplied to special quality assurance requirements, including KTA 1408.2.
