Mild Steels Electrodes

ES 55.00 A5.1: E 7018-1 / EN 499: E 46 5B 12H5

Description

ES 55.00 is a basic coated electrode for high quality weld joints with highest strength. It is suitable for welding steels with low purity and high carbon content Weld metal has high impact strength at low temperatures ductile down to -60°C. Good weld ability in all position except vertical down. As the weld metal is very resistant to hot cracking. It is used particularly to weld rigidly restrained mass structures where high welding stresses are unavoidable. The slag is easy to remove and it gives very high quality, smooth weld beads. Deposit has very low hydrogen content, it has 125 % metal recovery, re-drying is 300°C, min 2 h.

Applications

ES 55.00 is especially suitable for fine grained structural steels having high yield strength values. It is designed for steel constructions and machines operating under dynamic forces at low temperatures. Welding of ship's plate of A-, D- and E-quality, boiler and pressure vessel manufacturing and pipe connections are among its application areas. ES 55.00 can join steel parts to steel casts and can be used in the welding of thick parts. It is suitable for the root pass and welding in difficult positions. It gives excellent weld beads with high impact strength values at subzero temperatures.
