MEDIUM HEAVT COATED BASIC TYPE ALL POSITION ELECTRODE
EURO 320-15
CODING: AWS A/SFA 5.4 E 320-15 CHARACTERISTICS: A medium heavy coated basic type all position electrode giving a smooth arc, medium penetration and least spatter. The slag peels off easily leaving a smooth bead having fine ripples. The weld deposit can withstand temp upto 1200°C in continuous service. Excellent resistance to chemical corrosion and heat. TYPICAL APPLICATIONS: • For HV-9A stainless steel, alloy for high temp service, • For fabricating carpenter 20 stainless steel. • For applications where resistance to severe corrosion is required. • For a wide range of chemicals including sulphuric acid and sulphurous acids and their salts. • For repair of castings having similar chemical composition. SPECIAL INSTRUCTION FOR WELDING: • Keep electrodes dry. • Do not exceed recommended limit. • Hold short arc. • Ensure good fit-up on joints. • Adopt proper sequence. • Remove the slag with a stainless steel wirebrush. • Do not use excessive current. • Re dry electrodes at 300°C for I hour for better results.
