TYPICAL APPLICATIONS
• For Welding API 5L-grade X-70 and X-80 Penstock, earth moving equipments and heavy steel Fabrications made from High tensile steel.
• Excellent for welding fully killed fine Grained steels.
• Welding High Tensile steel SUMITEN 690
• Used for penstocks.
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.
DIFFUSIBLE HYDROGEN CONTENT IN THE WELD METAL : 2.0ml / 100g of deposited weld metal, Maximum.
