Bit more info would be good, such as, what is it ect? End of run certainly looks as if there is plenty overlap!

it`s a vehicle lift,it`s not so much the weld,more the fact that it`s been welded, and still cracking.

is it all in true? is the weld cracking or is the paint non elastic?

basically,it`s a car lift at a place of work. it previously cracked (hence the new welds. there are more than the pics show) and it`s now cracking again along the gusset plate,but can it just be welded up and put back into service and would it need the relevant safety checks ?? and if anyone can enlighten me on the relevant procedure,that would be great btw.
sorry there`s not more info,but i don`t really want to say too much at the moment, (small world and all that),just wanted to know what people thought regarding it`s use.
meant to add..... the cracked/painted welds are original.

Procedure would be down to a welding engineer, who would require lots of info as matl spec, max weight ect. I would imagine insurers would require to be informed also.
Regarding more cracks than picture shows, I would suggest this lift is withdrawn from service till a thorough safety check has been done prior to any hot work repairs!

A two poster by the looks of it, quite a lot of leverage on them arms.
Its difficult to see just how its made from such a close picture.
Not sure of the the rules about repair, but its probably started to go due to abuse, overloading...then a bad repair effected, which allowed the thing to carry on cracking?

apparently ins insp/engineer has seen it (during an routine insp. NOT by invite to inspect the `repair`) and was`nt very impressed,but i don`t know the outcome. it`s still in use
runnach,it`s `more welds than the pics show` not more cracks. i was`nt very clear there,sorry.

it`s been used for the same vehicle type since installation and is rated over the weight it lifts.

I'd put money on it ,that the weld was done by a fitter used to welding bodywork. No sign of grinding out the cracked weld just cleaning up the surface to be welded, by a mig that is normally used for car bodywork and laying a bead on top, with a mig welder that might be 180/200 amp max. The lifts welds need the paint removing and crack testing, then the welds grooving out, possibly preheating and re-welding with lo/hi's. Well that what I'd be considering.

to be honest,i thought a new arm would have been the order of the day,especially before it was welded up.
thanks for the replies chaps,i`m gonna leave it at that now as i don`t want to divulge too much because i don`t want to drop anyone in it.
if there are any developments,i`ll let you know.
thanks again.

CORRECT.. although it has been ground out slightly.

I agree with runnach, withdraw it from service. You just cant take chances with lifting equipment. The repair looks poor. If I had this to repair the first thing would be to contact the manufacturer to find out what to weld it with. Could be a high strength steel. If they couldn't or wouldn't help then get it analysed. Once repaired it will then need testing. I think if that failed and some one was hurt things would get bad real fast. That includes for the guy who has tried to weld it.

Not knowing all the ins and outs, BUT this is a form of lifting device, and therefore comes under such regs, SWL etc.
I would say any modifications, (and this would be classed as such) then it needs to be retested before been put back in service.
Addition; Tino can type faster than me

Slightly would be an understatement I suspect. The mig welder used to build the lift is probably 350+ amps capacity, the weld will have been done by automatic robot welder.
More repair welds? The manufacturer should be informed and the lift banned from use until something is done about it.
