Cryomate-6:

CRYOMATE-6 is a basic coated, nickel-base alloy electrode designed for welding of 9% Ni steel

Suitable for all positions, except vertical down.
Operates well on AC or DC(+), and with a fairly wide current range.
Welds are of radiographic quality.
Coefficient of thermal expansion is similar to that of 9% Ni steel.
Excellent impact toughness at - 196°C, combined with requisite tensile strength.
Also suitable for low alloy & hardenable steels, requiring PWHT, and for joining these to austenitic steels or high nickel alloys.

Thorough cleaning of joint faces is imperative to prevent pores.
Use short arc to the extent possible.
Ensure minimum amperage consistent with proper fusion so as to control heat input.
Stringer beads are to be preferred, but weaving, when necessary, be restricted to less than 2½ times of the core wire diameter.
Redry electrodes for one to two hours at 250°C-300°C.
Transfer them to holding oven maintained at 80°C-100°C.
In order to avoid crater crack, fill up crater properly and draw the arc away to the side.
Preheating & interpass temperatures and PWHT may be employed as necessary for base materials.
