Just a quick explanation of what I posted earlier about vertical welds on factory frames:

From "Welding Essentials" by William Galvery and Frank Marlowe. . .


"Do not place any welds perpendicular to the channel. Welds perpendicular to the channel concentrate stresses on just one section of the weld. This is because end welds on the patch plate prevent beam stress from being distributed evenly along the weld length. They become a new stress riser and will produce near term failure."

This is also what is taught when I took my AST apprenticeship.
