Other than "One that does not break" what makes a perfect weld?

Reply:I am a pragmatist when it comes to perfection.  I think your first requirement is the main one, not breaking, no inclusions...you know, the basics.  Aesthetics are nice but not a requirement.  I have seen welds (like cars) that are enviable, but to me a Toyota Camry of a weld (not a ferrari) is what I am shooting for.Smithboy...if it ain't broke, you ain't tryin'.
Reply:The prefect weld, easy................one with a big C beside the xray results I'd rather be hunting........USE ENOUGH HEAT.......Drifting around Aussie welding more pipe up, for something different.....wanting to get home.
Reply:That isn't an easy answer type deal. It is all in what you are after in the first place. I have seen some butt ugly welds hold way more than we ever thought they would...and some very pretty looking ones break at less than half of the designed loading. As long as it works, I'm happy. I have a grinder or three to make it look better just in case.
Reply:IVe found there is no such thing as a perfect weld.  Just one that passes.  There are too many variables.  As long as you do the very best you can, and it covers the min requirements, youre goodIF it Catches...Let it Burn
Reply:My opinion of the perfect weld. It does not break, which means it has enough weld  but no more than  necessary, [any more weld than needed is a waste of time and material] it has been welded with enough heat to get the job done but no more than necessary to keep the heat effected zone to a minimum, last and least it should look good. A weld that looks good gives your customers confidence in your ability as a welder.
Reply:the perfect weld....hmmmmmmmmmusing the proper filler rod in the proper application...it dont break...it takes little or no resistance getting the flux off it (stick)...no spatter but good penetration (mig)...whatever i do with aluminum cosmetics (to me anyway) is everything  ...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:To me a perfect weld is one that meets the specifications required for the application.  I've seen some pretty spiffy orbital welding robots that do autogenous TIG on stainless pipes that have had joints prepped to a tolerance of a few thousandths of an inch.  The resulting welds are about as perfect as it gets and also probably not something one would use on schedule 40.-Heath
Reply:I agree with above comments in general. Regarding cosmetics....the very thing that got me interested in welding in the first place was the beautiful work that was done by the welders at Rocketdyne's rocket engine plant in Canoga Park, California. They did their work on aluminum, magnesium and stainless steel on ducting and other engine parts. Each weld was X-rayed and stamped with the stamp of the particular inspector. In order to be passed by the inspector, every last weld had to be perfect from a functional and X-ray standpoint and also from the aesthetic standpoint. There were beautiful rows of curls where the filler rod touched the welds, almost with a machine-like look. They looked like something that might be seen in a museum of industrial technology. This was long before the advent of widespread use of computers or robotics. Also, there was no such thing as square-wave welding technology. It was all done on transformer-driven machines which would be considered primitive nowadays. I presume that much of it was done with Helium as the shielding gas. Those folks sure knew how to weld!It sure made an impression on my then youthful mind. Sadly nearly all of this beautiful work is underwater with the rest of the rocket which usually fell in to the ocean after burnout.
Reply:The perfect weld here is when the inspector looks it over and then says zinc it!
Reply:I guess inspectors have their place, but sometimes they are just "protecting their jobs". But, in respect to them, sometimes they aren't sure of whats expected. I've had to put up with inspectors in private companies, and the gov. jobs.  and in the AIR Force, i was a "recip engine mechanic " . i quickly learned to "play the  game" . I would purposely leave a couple spark plug leads LOOSE, and maybe one hose clamp loose(all in easy to find and easy to fix locations . ) The inspector found these , wrote them up , and WAS happy . (it JUSTIFIED his job ) isn't this SICK ? but, that's life . I found privatecompany jobs no different than U S  GOV  jobs . What i hated was (private  job) was when things got  SLOW,  they'd have an inspector check my job, he'd write up something, then they'd send a different inspector to re check it, then a different , etc. , etc. Just to "justify their jobs ". wa$teful !
