we it's general welding in manufacturing, we make coolers - radiators and air conditioning units often these require welding for cases and support brackets etc.
What is the current welding standard, or what standards can i reasonably refer to. It seems that at work we don't have a given standard we adopt/abide by. We have a BS499 hanging around but someone reckons it is no longer used. What should i refer to ?
We don't really have any to test on and the switches are quite expensive. We have settled on 4 Nm as that is the lowest torque we can set (yes very scientific I know....) and it seems to be nice and tight but not too tight to do any damage.
I've been asked to put torque settings on nuts that are holding switches onto panels and glands onto the back of boxes.
The supplier of the switch recommends 15pounds but that is only 1.6Nm which surely is ridiculous and is the same torque required to turn the switch so I'd think it risks...
