OP 128TT

OP 128TT is a fully basic agglomerated submerged arc welding flux that is reommended for high productive welding procedures in unalloyed and fine grained low alloy steels requiring high integrity welds with high toughness properties at low temperatures. OP 128TT flux, in combination with a range of Oerlikon submerged-arc wires, in particular with OE-SD3, is established for the welding of windtowers and giving a high level of consistency and mechanical property performance. The flux exhibits a low hydrogen content in the as manufactured condition and gives a high resistance to moisture pick up during exposure under workshop conditions. The flux promotes a very stable arc characteristic during use with excellent slag detachment in narrow gap welds. The weld is of a uniform even profile with regular fine ripple formation and smooth toe blending. OP 128TT flux is suitable for use with DC+ or AC and is ideal for single wire, tandem arc [DC+/AC] and long stick-out.

Features

• Highly basic flux for multiple passes applications
• Easy slag removal even in narrow groove
• High current carrying capacity making it suitable for high productivity procedures
• Excellent behavior in multi arc and long stick-out process.

Special Features

• Current type : AC/DC+, Basicity (Boniszewski) : 2.2, Grain size (EN ISO 14174) : 2-20
