Radiographic testing requirement for welds: Grade I

Shielding Gas: CO₂

Precautions:

1. For multi-pass welding, the interpass temperature shall be controlled between 135 °C and 165 °C.

2. The shielding gas flow rate shall be maintained at approximately 15–25 L/min.

3. Prior to welding, remove all impurities from the base metal surface, including rust, primer, oil, grease, carbon-arc gouging scale, and welding slag.
