The retardedness regarding the regurgitated interweb "welding facts" I find amusing. Very amusing...Ever heard of weld creep? No, you most certainly haven't.
Everyone seems to claim they're no welding expert, yet continue to speak as one. I've been doing this 20 years this coming February, and I'm still no expert. I've been certified in D1.1, D1.2, D1.6, D14.3, and D15.1, structural, holding tanks, pressure vessels, prototype weapons and weapons systems for the DOD, in most processes (you don't SMAW weld aluminum), and in all positions. What have you "experts" ever been certified in and done on a daily basis to put money in your pockets?
2" of weld and let it cool completely. Sure. Keep dreaming...Obviously you've never worked a pipeline, oil rig, production shop, job shop or OEM manufacturer. You wouldn't even pass the welder qualification test. Seems to me you've read crap on the interweb and bought into it...
Control your warping through skip welding here and there...only if you're a ****ing welding engineer genius. Computer programs now figure that **** out so that every part is right the first time, and every time after that. Anything less is a guess at best...
If you can properly explain to me a simple GMAW weld procedure, and what changes affect welding characteristics and properties I might listen...Bonus point for explaining anything difficult such as electrode chemistry, affects of reactive and non-reactive gasses and their different mix ratios and advantages and disadvantages with each, stickout and contact tip/nozzle length ratios, as well as metal transfer modes and deposition rates and anything else you happen to know. And lets just stick with mild steel for now. We can get into stainless steels and aluminum alloys if you wish at a later time. GTAW, SMAW, SAW, and CAC if you so desire as well.
Otherwise STFU and listen to Blaine as he knows what he speaks. And so do I.
If you want to learn, listen up. Otherwise go pound sand and continue to be a wanna be welder.
