STEELOMATIC-347 L
STEELOMATIC-347 L
DESCRIPTION AND APPLICATIONS: STEELOMATIC –347 L is a semibasic type stainless steel electrode depositing an extra low carbon 10 Cr-9 Ni-Cb stabilised weld metal which has excellent resistance to the intercrystalline corrosion and heat resistibility. The electrode is used for welding AISI 347, 321 and 304-L and their equivalent grades.
NOTES ON USAGE:
- Ensure that electrodes are dry enough. In case of moisture pick-up, ready the electrodes at 250°C for 30 to 60 minutes. Thereafter, either allow the oven to cool slowly to about 60° C, or transfer them to a holding oven maintained at 50°C – 60°C.
- Clean the joint faces to remove moisture, grease or any foreign matter.
- Employ welding currents within the prescribed range.
- Keep the arc as short as possible.
- Restrict weaving of electrode to within two and a half times the core wire diameter.
- Use stainless steel wire brush for cleaning the weld beads.
