VOLTAWELD V-502 / VOLTAWELD V-8018-B6
AWS Specification: E502-16/E8018-B6
JIS Specification: DT2516
Other Specification: DIN ECrMo5B26

Applications

Welding of 5% Mo steels such as ASTM 387 Gr. 5 used in oil refining chemical industries and electric power plant.

Welding of quenched and tempered high tensile strength steel for air craft parts.

Characteristics

N-502 is a low hydrogen type electrode for all-position welding, which provides the weld metal containing 5% Cr-0.5% Mo.

Notes on usage

(1)   Dry the electrodes at 325-375°C for about one hour before use.

(2)   Preheat at 250-350°C and post heat at 730-760°C.
