Perhaps so. But suppose I need to break the lines every six months? Or it's a petrochemical line that won't rust? Or that it's not a piece of scrap pipe in a boneyard but a gas connection that's indoors. No one's arguing against welding--just for making a connection appropriate for the service.

Taking your example a step further, if I thought a fitter was going to be fighting a rusted connection like hell and getting blue in the face and breaking his ribs, I'd probably tell him. 'Burn the line at the fitting and rethread it and be a little more careful next time to keep it from rusting.' And if he suggested welding it I'd tell him, 'Suit yourself, but you're going to need a qualified welder and you'll need think about how much work it's going to be next time you need to break the line.'
