Mild Steels Electrodes

ES 45.04 A5.1: E 7018 / A 2560-A: E 42 4 B 32 H 5

Description

ES 45.04 is a basic coated electrode engineered for high quality welds. Excellent strength and toughness properties also suitable for welding steels with low purity and high carbon content Good weld ability in out of position work except for vertical down. It is used particularly to weld rigidly restrained mass structures where high welding stresses are unavoidable. Weld metal has a high resistance to cracking, The slag is easy to remove and it gives very high quality, smooth weld beads. Deposits have very low hydrogen content, it has 125 % metal recovery, re-drying 300°C - 350°C min. 2 h.

Applications

ES 45.04 is suitable for steel constructions and machines operating under dynamic forces. Pipe connections and ship building, boiler and pressure vessel manufacturing, container making, vertical construction shipbuilding, machine construction as well as for buffer layers when building up high carbon steels are among its application areas. It is recommended for the welding of high carbon steels having high P and S content; Welding of high strength ship's plate of A-, D- and E- quality and vessel plates of 17 Mn 4 and 19 Mn 5 type. ES 45.04 is also suitable for welding thin plates in the small diameters.
