There was a firm cutting trees down near electric lines here. When one quad got stolen,police caught him and the van that was meeting him. In the van was a photocopy of the consent maps that the farms sign to give permission for the work and each farm with a quad was circled. None of the blokes had any connections to the tree surgeons other than the mapIm convinced the folks that nick the stuff get informed by others that genuinely come to the property ,,it cant all be random

I’ve not bought anything second hand but often trawl the auction sites ect for equipmMakita 1/2 inch drill in box , 2 very old iron bars , tyre levers socket set, extension leads , portable engine hoist .... the location is one mile from caersws in Mid Wales l
I'm in that trade (as a customer engineer, not a welder) and I can assure you, MIG/MAG is widely used for pressure vessel fabrication!Actually no , Mig is not accepted for high pressure vessels (boilers/ steam pipe ) but MMA is .
Tig route with low hydrogen rods is how I was taught to do boiler steam pipes .I'm in that trade (as a customer engineer, not a welder) and I can assure you, MIG/MAG is widely used for pressure vessel fabrication!
It's not generally used for repair work, because of the issues with spray MAG when not in flat position, as well as logistics of gas shielding etc. Much easier for repair shops to have a set of MMA or TIG certs. Much easier to assure quality on pipe with TIG, too.
In the case of fired boilers I'm not sure, maybe you're right, it's always been TIG repair where I work and I don't get involved. But for unfired vessels made to PD 5500, MIG/MAG is acceptable, if done to the right standard (BS 15614/9606 and certified by the right body)
