What do you think of this technique, Will my roof fall in??

[magnethead123]

Hi, these are my Roof beams just going in, can you tell me what you think of the welds please, if you are an experienced welder.
Are Butt joints ok being at an angle like that?

Thanks

THe Roof is fairly lightweight as far as roofs go, (EPS panels) which will have a light wooden structure cover with metal)
Not that that excuses bad welding

I'm gonna need some fast advise if these are to be ripped out , tomorrow they are supposed to be cemented in place

 

[mtt.tr]

Check they are to en1090, if you have doubts then ask for certificates and NDT testing.

Really we cant give opinions of these via a forum


If you are worried stop the job. Huge liability issue really not worth it, ignorants is no defense in the eyes of the law

 

[magnethead123]

Thansk for the reply, I am a bit clueless , what is en1090? IS that a welder cert, the builder welded these. I guess I need to be asking for his certification. THe steel itself is certified.

Is this against the forum charter to give opinions on stuctural steel, or you mean you'd need to see the welds in the flesh to give an opinion?

THanks again

 

[Yamhon]

Can't comment on the welds, people may want to know more details such as process, amps, any preparation, any testing you've done, etc?

Although the picture of the top plate attached to one of the beams, and pinch of salt territory as I'm new; but that weld specifically looks like there is a lack of fusion to the top plate, is this a cap for a multiple pass joint?

On the angle of the butt welds, there might be engineering considerations regarding stress and forces outside of the quality of the welds also.

Welded on site. That adds complications. Are they to a design spec created by a structural engineer, he would of specified if it should be welded or flanged

 

[Tinbasherdan]

Number two it appears that there is little to no “wetting” at the toe of the weld, I would put reasonable money that there’s lack of fusion. I wouldn’t be happy putting them up

 

[magnethead123]

Yamhon, I can't tell you how the weld was done or if it's a cap, they were done in the builder's yard away from the building site.

I'm giving my stuctural Eng a call in the morning, and the company who are providing this whole system, as this ICF company is signing off on the house shell itself and technically this steel work comes under their engineer...oh the joys of building

 

[eLuSiVeMiTe]

The fact your here asking for opinions shows you have your own doubts.
I wouldn't employ a builder to weld structural steel on my jobs.

 

[magnethead123]

Yes eLuSiVeMiTe, It's exactly that point, that had me thinking.......IS this right

 

[Parm]

I’m not a welder but to my untrained eye they don’t look right.

Some folk on here (can’t recall whom) do structural steel work for a living and know all the codes, rules and regulations

I’m sure some will be along soon

 

[eLuSiVeMiTe]

It's cheaper than getting a welder in. Who knows they may have there own in house welder. Alternatively he might have a welder kicking around in his yard and decided to chance it.

Those but welds ...are not pretty. I assume they are where the wall pads sit, carrying all the load in the vertical plane.

Not sure what your drawings by the engineer state, but for my current project, states steel sizes with welds, but nothng regarding weld spec, it sort of implies welded by a " competent" welder, its awfully vague.

As said if your not happy you need to seek speacialist advice...inspection etc

Did the builder weld them, or bring in a welder?

Built of site needs en1090 coding as could prevent atleast slow down building sign off.
This is something i contend with often on building jobs, best place to find bodgers.

 

[Tinbasherdan]

at the very least it’s rough as a bears arris, there appear to be multiple visible defects and as such I would recommend a proper welder is contacted to grind out the crud and reweld

Our last steel we had made up we got a really good run down on the drawings giving fillet size and what not.

Still had them made up, not my day job.

i can tell you now they are not sound this is how it should look

and as a builder who fits them in often the only part im welding is a stacker plate when the steel beam needs to be filled up to the right level for the next beam

 

[jimbo84]

I'm definitely no expert but have they welded through the primer, looks like very little preparation to remove the paint.

Wouldn't bat an eyelid fitting the above.
Original images made me cringe

Ive always just welded my own steels, but its normally just mounting plates, feet, and tabs to fix joists too, so not really weight bearing, in the way they are in the picture.

Only tabs this time, not really required but engineer does like to over complicate simple things.

I once looked at a barn conversion, lovely house, but walked away as the exposed steels were held with bird poo. Guy who bought it had them redone.
