Welding the seams: INSIDE

Before stating to weld we positioned an aspiration device



Then we started welding. I had a lot of thinking on where to start, transversal or longitudinal.
On Robert instructions it said transversal according to Kasten paper on metal boat builing.
But Kasten in his paper says longitudinal first. The topside plates against the radius seams have already a perfect fit and they do not need to bend. If we weld the transversal first they might move and it would be difficult to bring them back in position. And they are in the final position now.
So longitudinal first and let's hope for the best!




Then the transversal radius


And when possible bilateral!
