Oerlikon Tenacito 80CL description: TENACITO 80CL is a low-alloyed basic coated MMA electrode with a very low hydrogen content. The electrode produce a reliable, crack-free and tough welded joint on steels with a yield strength <700 MPa. The weldmetal is of a extremely high metallurgical purity, retaining good CVN toughness up to -60C and CTOD tested. For optimal conditions a good balanced t8/5: (heat input, interpass temperature, plate thickness) is recommended. The TENACITO 80CL is used for HYSS, applications with a higher yield strength up to 700 Mpa and down to -60C. The double coating in dia 2,5 and 3,2mm, confers a stable and concentrated arc, even at low currents, makes it very convenient for root passes and positional welding.
