Does seamless fluxcored wire results in higher quality and less welding cost in shipbuilding?

One meter FCAW filled weld with an height of 4 mm is costing approximately € 6,- per kg including labor, welding wire, gas and devaluation of welding equipment.

If we zoom in we can see that the cost for welding is divided as follow:

Especially due to the high labor cost of € 40,- / € 60,- per hour in the Netherlands we see that 80% of the welding cost are absorbed by labor so this is the part where we should put the focus on (says the American 80/20 rule)
If we manage to increase welding time with 10% we already earned € 8,- (10% from € 80,-)
