ELECTRODE FOR WELDING MILD, MEDIUM & LOW ALLOY STEELS


SAITRON 101 ALFA
Description:

SAITRON ALFA 101 is medium coated rutile type all position electrode. It is suitable for welding structural steel. The weld deposit is of radiographic quality & with consistent mechanical properties. The weld bead is flat, shiny and finely rippled with less spatter and excellent slag detachability.

Applications:

Storage tanks, pipes, Machine frames, construction equipments, sheet metal fabrication, steel structures and frame works, truck and bus bodies. Welding mild structures steels like IS: 2062, IS: 226, etc.

Note on Usage:

Keep the electrode in dry place. It is always better to redry the electrode at 1000C to 1100C for 30 minutes for the best results. Use welding current within recommended range. Degrease to remove oil and grease. Use electrode on AC / DC +. Can be used with contact arc.

SAITRON 102 LH
Description:

SAITRON 102 LH is heavy basic coated electrode for all position. The weld deposit provides metal recovery min. 110%. The weld metal exhibits excellent impact properties down to -300C and ensure radiographic quality. It is suitable for welding C-Mn steel and heavy structures.

Applications:

Boiler and pressure vessels, penstock, structure and other components under restrained conditions and dynamic loading, ship building, steel of doubtful composition, grey cast iron buffer layer prior to hardfacing etc.

Note on Usage:

Keep the electrode in dry place. It is always better to redry the electrode at 3000C to 3500C for 60 minutes for the best results. Use welding current within recommended range. Degrease to remove oil and grease. Use electrode on AC / DC +. Hold short to medium arc. Can also be used for contact welding. Clean weld area to remove surface contamination and gouge/grind all cracks. Slag removal is easy, Preheat is usually not necessary unless very heavy sections are involved.

SAITRON 185
Description:

SAITRON 185 is a basic coated Cr-Mo-Ni alloyed, low hydrogen, radiographic quality electrode for welding of low alloy high tensile structural steels. Including quenched and tempered steels such as USS Ti, heat treated fine grained steels like N-A-XTRA 70, HY-80 and ASTM A517 grade F. Used for heavy section of high tensile steels with good ductility and crack resistance along with high notch toughness at temperatures upto -500C. SAITRON 185 offers good arc characteristics and easy slag removal. Suitable for operating temperature from -500C upto +4500C.

Applications:

It is used for welding of 78 kgf/mm2 high tensile steels. Pen stock, Pressure vessel, Earthmoving equipments and other heavy steel fabrication made from high tensile steels. Welding of USS T-1, C & D Grades of SA-225/225M; B, C, D grades of SA-533/533M; B, C grades of SA-543/543M. Heat treated fine grained steels N-A-Xtra 55 upto 70, HY 80 etc.

Note on Usage:

Rebake the electrodes at 350°C for 1 hour and keep it at 150°C prior to use. Gouge out/grind, worn, damaged and fatigued metal/cracks. Clean weld area. Use electrode on AC/DC+ at the lowest amps. Keep the arc as short as possible (can be used for ‘contact welding’ also) and chip slag between passes. Peen the weld deposits while hot. Avoid weaving. Use lower current. Preheat is usually not required unless very heavy sections are involved.
