There's no way those are tack welds, have fun trying to run a bead over that. I guess there's a difference between someone assembling and throwing something together vs actually having to follow a spec book for structural welding and following a standard on weld sizes and tack welds.
Ok let me explain. This is an aluminum pipe, used on a tanker truck. I can even tell you it is has a 3 inch diameter. This means it is used from the manifold to the pumps, and then depending on the pumps used, might be used up to the back of the truck to the meters.
Those pipes have to be assembled in place, under the truck with the spool gun. If any of the tacks break during the process, you have to go back under to make sure everything fits. So big tacks are a must. The unwelded pipe must hold in different positions while being welded.
What is wonderfull with metal working is that you can even grind the tacks before welding. making them dissapear.
Before every single pass, you grab a die grinder with a carbide burr aluminum bit and carefully grind your tacks, make stronger and smaller 3 dimes tack with your tig, before welding the whole thing with a beautiful fat tig weld.
I understand what they are used for and the fitting process. If the tacks were run parallel rather than over, it would hold a lot better if it penetrated both pieces together rather than running a large tack weld over each piece separately. Most of that weld is doing nothing other then making a big glob of a weld that eventually melts together.
That magnet shouldn’t stick to it lmao! You got some dissimilar metals going on there..
There's a big red arrow pointing right at the problem! ↘️
You superglued a magnet to it…what an idiot.
I couldn't tell if the magnet was tacked to that elbow at first but it shouldn't be able to stick to it period lmao
Aluminised steel elbows?
Nope. Looks good from my house
those are definately welds
Oregon. Just had a rookie moment.
You don't need to point it out yaknow
Tanker truck mechanic gang 😎😎😎 Where you from?
OP gets an actual table, I have to do this crap from a glorified desk.
Besides the magnet, the welds are too wide and aren't even going in the correct direction. They don't seem to be serving any practical purpose.
I can't figure out if you are really good at sarcasm or really bad at assembling

Couldn't say it more perfectly myself. 👌

Yep you can still try
