Mild Steels Electrodes

ES 47.00 A5.1: E 7016-1H4R / EN 499: E42 5 B 12 H5

Description

ES 47.00 is a basic coated electrode for high quality weld. It gives excellent quality, smooth and homogeneous weld beads with a very impurity ( like P and S ) content. It guarantees a yield strength value to 430 N / mm for medium and high strength steels. Weld metal extremely ductile and crack resistant, thus especially suitable for rigid weldments with large seam large cross section. Good weld ability in all positions except vertical down. Metal recovery is about % 100, deposits have very low hydrogen content. ? 2.50 or ? 3.25 mm electrode selection in the root pass brings homogeneous weld beads due to full penetration, which brings great advantage in special welding applications.

Applications

ES 47.00 is designed for steel constructions and machines operating under dynamic forces. Pipe connections and ship building, boiler and pressure vessel manufacturing 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. B - 5 can join steel parts to steel casts and be used in the welding of thick parts. It is suitable in the root pass and recommended especially in applications where high impact values are required at - 30 C or - 40 C.
