TYPICAL APPLICATIONS
• Specially recommended for welding ASTM A517 Gr F Q&T steel. Excellent for welding fully killed fine grained steels. The electrode works in all position gives very little spatter with an easily removable slag leaving a bead of nice appearance. The electrodes should be redried at 350 – 400°C for 2 hours to obtain better result.
• 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.
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. Maintain interpass temperature below 120°C.
DIFFUSIBLE HYDROGEN CONTENT : 2.0ml / 100g of deposited weld metal. (Typical) in the weld metal
