Got a little boat welding project. Aluminum boat that is separating at the seam. Long crack, 18in to 2 ft long. Owner has been covering crack with silicon to stop the leak. Of course the crack keeps growing and only real fix is to weld. Anyways, I dont see anyway to get behind the crack to remove any silicon that has been pushed thru the crack during application. I will have to tig the weld since I dont own a spool gun and just wondering if cleaning the outside only will be good enough to get a decent weld.
