I know a decent weld when I see it and I make acceptable welds. You've never posted anything that makes me think your opinion is more valuable than mine. Are you a professional welder?
As an engineer, I also know the huge amount of force it takes to break, even a small piece of bar stock, or that same piece of stock, adequately butt welded together. In the case of the 1/8" x 1 " stock, it's area is .125 square inches. If the steel has a tensile strength of 60,000 psi, it should resist a force of 7500 lbs. With that in mind, applying a force of only around 1000 lbs to it was a trivial test, but if the welding I did was really poor, it might have broken it apart.
In the real world, structures are designed with a safety factor that is many times the actual load. That's why those shock mounting ears are made of 3/16" x 2" steel and there's about 8 inches of weld length all around them. That creates a large safety factor. You'd have to make some really pititful welds for a bracket like I made to fail. Here's some information of safety factor.

As I see it, there are a number of forum members who dislike me and take every opportunity to made rude remarks. If that makes you feel good, have at it, but you'll have to use someone else as your punching bag.
