TYPICAL APPLICATIONS
• Penstock, earth moving equipments and heavy steel Fabrications made from high tensile steel.
• For welding USS -T1 steel, WEL -TEN 80 steels, SA 517 grade F and their equivalents. Specially recommended for welding ASTM AS17 Gr F Q&T steel.
• Excellent for welding fully killed fine grained steels and W36HI Tensile Steel.
WELDING PROCEDURE
Use short arc length. Weaving of electrodes, if necessary should be done at slow speed and keeping a short arc. The electrodes should be used in perfectly dry condition. The electrodes should be dried at 400°C for 1 hour to obtain better result. Maintain interpass temperature below 120°C.
