Duct tape. Fix it right up.
At $1000000, that’ more than $1500 per bolt.
Someone must have flunked welding school.
The bolts won’t attach to anything, but putting a bolt through the hole and a nut on the other end will increase the strength of the pieces, experts said.
I’m a civil engineer and a bolt through a hole attached to nothing else adding strength is news to me. Something is missing in this story.
I don’t understand how putting a bolt through the hole strengthens the piece of steel that the hole is in.
If the heat from the weld plug has already weakened the steel it seems that the damage is already done.
Any weld will not only change the temper of the surrounding metal it can cause stress. The formerly molten metal tries to shrink but is held back by the surrounding material. In some cases the stress is enormous. I used to design and build fixtures for assembling motorcycle frames. They had to be extremely strong to resist “weld pull”. The welding sequence was as much an art as science. A good welder had an eye for tacking and then welding in the proper order. We expected the first few frames out of a new fixture to be junk while he got the feel for it.
This reminds me of a story my dad told of a lady driving a Model A. She stopped at a filling station and the attendant noticed a crack on one of her fenders. He told her he could stop the crack from going any further if she would like. She said please do. He goes in and gets a brace and bit and drills a hole right at the end of the crack. She looks on with a perplexed look. She asks what that does. He tells her the crack goes into the hole and having no where to get started again stops right there. She says “ I’ll be damned, I always wondered what my belly button was for”.
What I got out of it is that this as much an art as it is a science, and the textbook answers sometimes mysteriously just don't fit reality. We ought to be giving the guys who try to get this right, the benefit of the doubt.
We could use a few in the House and Senate....
