Product Description

Product Description

SJ305
comply with standards ( Standards)

NB/T47018.5 FM347L-E

illustrate:
SJ305 the flux is strip cladding submerged arc welding calcium silicon type medium cladding process, stable sintering flux, smooth saddle bead surface is smooth and smooth.
use:
stainless steel strip submerged arc surfacing is used for surfacing the stainless steel corrosion-resistant layer (the second layer and above) of coal chemical industry, petrochemical offshore platform and other equipment.

deposited metal chemical composition:

C	Si	Mn	P	Cr	Ni	Cu	Nb
0.021	0.55	0.020	0.009	18.75	9.80	0.023	0.42

surfacing process parameters:
 

ribbon size (mm)	cladding current (A)	cladding voltage (v)	cladding speed (mm/min)	belt pole elongation (mm)	flux thickness (mm)	weld bead lap (mm)
0.5x30	350-500	26-30	140-200	25-30	30-40	5-10
0.5x60	750-1000	28-31	140-200	25-30	30-40	5-10

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.
