Many people ask what's better stitch welds or solid welds in the construction of the hull. I've read and heard that excess heat reduces the strength of aluminum and stitch welding is preferred since it reduces the amount of heat on the hull plate. Obviously there's no way around heating the bottom plate during the manufacturing of the boat but using techniques that minimize the effects of excess heat are required in most government contracts and the technique is used by many boat builders. I decided to do a test and the video link below should show why proper construction techniques that reduce excess heat during the build process is extremely important. I really wasn't expecting to see such a big difference. Watch for yourself and try it at home if the video doesn't convince you.
