FusoFlex

Silvershine-ZFU:

Semi-basic coated electrode for all welding positions except vertical top to bottom.
Soft & stable arc with ease of striking and with negligible spatter.
Self-peeling slag.
Smooth bead appearance with fine ripples.
Weldable on AC and DC+ polarity.
Fully austenitic weld deposit which displays a high degree of resistance to hot cracking.
Presence of nitrogen helps to increase the tensile & yield strength levels substantially.
Weld metal possesses excellent resistance to corrosion, especially in urea service. This is evaluated by ASTM A262 Practice C, i.e. boiling nitric acid test, also referred to as Huey Test. Suitable for AISI 316L grade and its Nitrogen-bearing variants, used in chemical and fertilizer industries.

For best results use electrodes on DC (+)
In line with the safe practices in welding of austenitic stainless steel, avoid build-up of heat, and keep the interpass temperature below 150°C.
Use short arc to the extent possible.
Minimise weaving.
Redry electrodes at 250-300°C for 30-60 minutes, after taking care to place the electrodes in the oven at room temperature. Thereafter, allow the oven to cool to 50°- 60°C and maintain at this temperature before removing electrodes for using.
