This highly versatile electrode is extensively used by the maintenance repair man. The high-alloy content, strength and elongation capabilities allow it to solve various problem steel joining applications. The specially formulated coating permits smooth, porosity free, dense deposits free from spatter. Undercutting is eliminated due to ease of welding and control of the arc. Deposit will take high polish.
ISOARC 168 is used on repairs to shafts, pinions, springs, tools and dies, gear-teeth, machine parts, earth moving equipment, agitator blades, pressure vessels and all welds requiring high stress loading capabilities.
To avoid the accumulation of heat, use low amperage with stringer bead technique and a short arc. Intermittent welding can be used especially on high alloy steels. On tool steels, preheat to approximately 200 degrees. Light peening of welds will increase the tensile strength.
Should electrodes become moist re-dry at 350°C for 1 hour
