Is This Weld Reliable?

[Robertt]

Hi there guys. I figured I should register in a welding forum to ask this question.

I bought a pull up bar, those you fix in a wall. The material used in the whole structure is carbon steel.

The structure has 95cm distance from the wall, and the bar that connects the structure has 1 meter.

What I noticed is that the person who fabricated this did not weld the parts "all the way through".

I got a bit skeptical (But honestly, I don´t know anything about welding and how much weight this amount of welding can hold, so...)

The type of welding used was MIG.

I inquired the vendor about my concerns, and he claims that this will hold up to 250kg, as is, that I don´t need to take it anywhere to reinforce the welding (as I wanted to do).

I weigh around 75kg, but I also wear a 20kg weighted vest for some exercises, so let´s round it up to 100kg as I will be doing movements which gonna put stress on the bar, I won´t be simply dead hanging.

I am uploading some pictures of it, so you can take a look.

Looking forward to hear from you, as it will put my mind at ease and I won´t be concerned when hanging from this thing, I just wanna trust the equipment.

Problem is you havent shown the welding.
And or sizes of parts.
Would have guessed its 50x50box and 40mm tube ish.
And then reckon strong enough for 100kg bouncing.

But then again most on here wouldnt buy anything like that as only like £20 worth of material.

Difficult to say Robertt! the welds are long enough to be strong enough, provided they are good welds, and have penetrated into both components properly, the only way to really tell is to cut them open!. this is a classic example of piece work welding, absolutely minimal!

 

[Munkul]

As long as they are good welds, then that much welding is more than enough Your biggest weakness will be where it attaches to the wall. Hopefully you can install them so the triangle is pointing upwards, that way you're hanging off the wall more than pulling out of the wall.

They'll be fine. I can't imagine they'd take the risk of under-engineering stuff like that, if they did and it failed catastrophically they'd be in a whole heap of trouble.

so would the person that fell off it

Guys thanks for all replies. I am adding a couple more pictures that better show the welding:

Honestly, they're going nowhere.
As someone else said, the rig is more likely to pull out of the wall due to inadequate fixings then it is to fail on any of those welds.

well braced up and cantilever main part under compression with diagonal support

 

[Screwdriver]

Much of the strength will be in the design and rely on managing the forces acting on the welds so they are not at a point of maximum stress. Forces will be distributed within the entire structure. It is surprising just how much effort it would take to pull apart even a single (full penetration) tack. If on the other hand the structure allows joined parts to twist or bend, it just needs a little bit of leverage and it comes right off.

Sound for what you want to do, used to swing about with a weight vest on much worse than that.

You could pick fault with the welds if you were being critical, but it's fit for purpose i'd say.
I gather its a mass produced item?, it should have CE approval etc... you could keep your reciept just in case, but i wouldn't worry about 100kg pulling up on that.

As ohers have said, the wall fixings will be the weak point, unless youre bolting it to substantial steelwork in an industrial unit or something

Hi mate, thanks for your reply.

Actually not mass produced, they make it when you order it, takes 2 days to fabricate...

 

[atomant48]

What are you bolting them to? I’d be more concerned about that, honestly. I’d want more than a couple self tapping screws, but them this forum has converted me to resin studs :-)

I might need to make something similar in the NY to work off some pigs in blankets.

sorry crossed posts but the same idea.

1" of weld will hold a ton.... itll be fine.

 

[fire hazzard]

The welds are probably done by someone on piece work, not the best visually but if the boss wants numbers over quality that's what you get. As previously stated they should be sufficient, unless your kali muscle and have a thing for muscle ups

is that regardless of width and depth?

 

[qwakers]

it assumes proper penetration.

 

[brightspark]

is that regardless of width and depth?

and orientation as its only welded on one side

I will be definitely doing muscle ups 3x per week, tops... The pull up bar will be constantly used because practically all my workout is performed using gymnastic rings, which gonna be attached to the bar. But honestly, I can´t think of another exercise on my routine that would put more stress on the bar other than the muscle up. After that we get the chin up and pull up which don´t require the same explosive pulling force of the muscle up, and the other exercises they will barely put any stress on the bar...

I have attached the bar to the wall using through bolts on the top.

The wall is made of concrete bricks.
