Welding Notes
· Clean rust, moisture, oil, dust and other contaminants from the weld area before welding.
· Recommended shielding gas: 98% Ar + 2% O₂; maintain a gas flow of approximately 20-25 L/min.
· Maintain a wire stick-out of approximately 15-25 mm and use suitable welding parameters.
· For outdoor welding, provide adequate wind protection when wind speed exceeds 1.5 m/s.
· Use controlled heat input and proper welding technique to maintain corrosion resistance and weld appearance.
