When I looked out the bedroom window early this morning I couldn't believe what I saw. A dry boat! Brilliant I thought, at last I can weld the roof beams to the sides. I had stuff to do in the morning and early afternoon, so when I got home it was still dry and no sign of rain. I set too.
I managed to get a few welds done before the water started
About 15 minutes in and it started raining. Great! Water started pouring in. The inside of the boat looked like the wall of a cave.
Not good conditions for welding
So instead of welding the sides I decided to weld the roof beams to the roof sheets. This area was not affected by the rain. I hate welding overhead and was sort of putting this job off. I have welded 6 of 9 sheets and have the splatter burns to prove it.
As this is not an area of high stress a stitch weld has been used. The benefits of this technique are strong attachment in proportion to the job, quicker than a seam weld and less heat put into the job the less distortion.
