VOLTAWELD VSS-505

AWS Specification: E505-16
JIS Specification: NONE
Other Specification: DIN ECrMo9B26

Applications

Welding of 9% Cr-1% Mo steel used for super-heater tubes of high temperature and high pressure boiler, heater tube for all refining industries.

Characteristics

VSS-505 is a low hydrogen type electrode for all-position welding, which provides the weld metal of 9% Cr-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 720-780°C.

(3)   Adopt back step method or strike the arc on a small steel plate prepared for this particular purpose to prevent blowholes at the arc starting.

(4)   Keep the arc as short as possible.
