Just ripped up and replaced the floor with new timber & carpet, cleaned the inside of the hull and all looks mint. Only problem is I noticed a cracked weld on the front port rib.

I have access to a mig welder set up for ally welding, but unfortunately my mate and myself are amateurs (will be removing fuel tank) so before we decide to tackle the job does anyone have any advice & has anyone had to do this before? 

It's a quintrex 490 (I have checked all other welds and they look fine)

Anyway, I've added pictures of the old & new floor along with a picture of the broken weld.

Cheers in advance
