Frequently Asked Questions
Baking electrodes at 150±10℃ for one hour removes moisture from the coating, preventing porosity and ensuring a stable arc during the welding process.
It is recommended to hammer the welding seam to eliminate residual stress and use the smallest possible current to reduce the width of the white band.
The joint should be obliquely cut into a U-shaped groove. Additionally, stop-crack holes should be drilled at both ends of the crack to prevent expansion.
These electrodes are designed for PA (flat) and PB (horizontal) welding positions, providing excellent bead control in these orientations.
Yes, it is effective for Fe-C-Si based industrial cast irons, commonly found in engine shells, machine bases, and various casting parts.
Use short and thin welding beads with a narrow lateral swing of the torch. Maintain a medium arc length and a slight incline in the welding direction.
