Fun fact . 347 has same amount of chrome and less nickel than 316(19-12-3 ). 347 is basically a 18-10 or 19-9 with niobium in it for heat and rust resistance (its basically a 304-308 with niobium or nb short) , which is being used to weld on 321 material (which is 304 with titanium in it or short ti) . 321 itself has also different varients like for example 321H to name one.titanium and niobium are being used to lower the crome carbide formation. ( chrome carbides make the steel lose its chrome oxide layer , in turn makes it rust ) chrome carbides typically forms when there is too much carbon in the steel that bonds with the chrome so that leaves the iron without the chrome protecting it . The 316 or 19-12-3 variant (which is better resistant against acid and chemicals than 304 and 321 ) has about 3%molybdenum in it which makes it brittle at higher temperatures ( there is a term called 475°c embrittlement ) , therefore its only qualified to be used under 400°c max for that reason . Hope this is clear enough to be understood . Ps the welder took his sweet time to weld that , which i do not blame him for . I personally would weld it with higher amps and go much faster . Still good job
You can’t necessarily make a robot (ai) walk the cup or tig weld in general, mig would be the only process I can see them using them with really… I hope notat least😂
Applications for every need. Maybe they find less room for error or easier to weld with wild fit ups, not matter the joint configuration. Looks nicer etc. Those are my opinions
Robots do take job's, Ask some old Cat welders before bots were introduced, ask them how the pay scale went down because of no need for skilled welders The welding line became just part's flippers.
Good for them. They have a reasonably easy jobs and probably get paid pretty well for it. I get to weld the same part 20 or so times a day for the foreseeable future for $17 an hour.
