Smoothcor 81T1-B6 is a low alloy steel electrode intended for single and multiple pass, all position welding of certain chromium-molybdenum steels where a weld deposit of 5 percent chromium and 1/2 percent molybdenum is required

• The smooth arc transfer, low spatter and fast freezing slag make this an excellent choice for welding in all positions
• Increased deposition rates over covered and stick electrodes and a greater tolerance of mill scale and rust
• This requires careful control of preheat and interpass temperatures, as well as proper post weld heat treatment
• The weld metal is intended to resist creep and maintain strength at elevated temperatures
• 25 volt (vertical up), 26 volt (overhead), 28 volt (flat)
• 305 in./min. (vertical up/overhead), 450 in./min. (flat) wire feed speed
