flux quality requirements:
Flux S content: ≤0.035%
Flux P content: ≤0.040%
flux moisture content: ≤0.10%
mechanical inclusions: ≤0.30%
things to note:
1.before welding, strictly grind the base metal to remove rust, oil, moisture and other impurities. the workpiece needs to be preheated
2.when performing strip cladding, try to reduce the thickness of the transition layer cladding while ensuring the shape of the weld. (3.0~3.5mm);the thickness of the corrosion-resistant layer surfacing can be appropriately increased (3.5~4.0mm).
3.the surfacing position is horizontal to 2 °it is appropriate to weld uphill from left to right.
