Knowing if any weld I've done is 100% strong/good enough is always something that I've struggled with to be honest, apart from testing the item to destruction/failure point, how do you chaps really know?
How soTIG(tungsten inert gas) helps you to weld stronger.
NDT - Non Destructive Testing
Gives you a damn good idea of if the weld is sound or not. Most experienced guys will know through their experience as to if it is sound or not, but the X-rays don't lie and we all sometimes have a bad day and a weld that isn't 100% sound
Personally, in my current role everything is x-ray tested. Previously I have had ultrasound and dye pen testing done to welds I have madeWhat kind of NDT do you do then?
I think it were Mark Evans, vet turned TV presenter/car nut who said that a 1" long weld should be able to take a ton of weight without giving way, I seem to remember him using a forklift to attach a huge weight on something he had welded. I don't have that kind of equipment to hand though.
It’s an old saying John but there is a lot to be questioned around it.There is a old saying
Stick is strong
Mig is quick
Tig is pretty
Things like this make me nervous, should that collapse that could well be manslaughter.
I think anything that is significant and structural should be proven to be correct just peace of mind it also can be used in your defence should something else happen and it fails , it makes doing my job hard everyone and their dog bodges things on building sites.
We all have or do take chances but we need to consider the implications.
That's why you get liability insurance, just in case it does fail.
None of us, I hope, intentionally go out and put a bad weld down in the hope it will fail. But then you could lay a million welds and one will no doubt fail even if through no fault of your own
