You'd be surprised what gets passed when time is running outNo way would NHBC sign that off!
If it breaks when someone leans on it you, your company, the "welder" and his firm are all up in court.
I would chuck them off site and cut out anything they've already bodged up asap!
building trade mate ...you should see some of the slagged together welds and bodged fabrications ive seen on some jobs.Is this windup

We used to knock them up in the workshop off a decent bandsaw. I'd have to be very careful doing them onsite I've got to say.These were cut and fitted on-site? Fitup is vital on stainless like that. Anything more than a fag papers gap and you're into issues.
Did the welder also do the cut/prep/fitup?
Nope, the guy managed to avoid it.has it ruined the glass??

I think you need to escalate up the foodchain, and not let them "have another go", tomorrow. Not sure what your role is (and perhaps best that you're not too explicit on an open forum!) but can you get the site manager or architect involved?Nope, the guy managed to avoid it.
The handrails are delivered on site and just fitted as they are. The balconies are long and if the handrail parts are coming quite close to each other, like 1-2mm gap in betwen, the guys try to weld it. Then they just grind the weld. The first balcony they tried, they cleaned the welds with a grinder disk and not with a flap disk. The handrail got completely distorted and needed to be replaced.
The next handrail they do tomorrow is composed of two long pieces lying with about 4mm gap in between. The guys will grind a larger gap and fit a bit of profile in. I can post the pics before/after if this helps.
Gaps of any description on thin stainless make life hard. I'm certainly not excusing the attempts above as there is a lot more going wrong there than bad fit up but 1mm is pretty acceptable But any more particularly on the out of position stuff and lack of experience is fighting with a difficult joint.Nope, the guy managed to avoid it.

A gap up to the material thickness is manageable with hand rail stuff, not ideal, but manageable, any more just makes life a ball ache, increases distortion, heat input and longer post weld clean up.
Edit: Basically 4mm is a bad idea!
Because you can slip the Q Rail system off the glass, cut it, tack it, then we carry it indoors or weld it behind the windbreak of the glass.How do you get on with stainless on a balcony like that do you ever get problems with gas coverage when welding on site. Its not like in an industrial situation and you can just tack or clamp some sheets up to protect from the elements.
