Here is a good "Quiz"

admin

My day job is inspection of all incoming tooling used in my place of employment.Measured and either it meets print or it does not meet print...Then it is up to an engineer (gaining) to decide if the part can be used.Our work can and will kill... The Machines are capable of such the product CAN kill and will kill... It is designed to kill. We deal with energetics and pyrotechnics... Explosives, Propellants and Chemistry. Most of the machines apply 85,000# of force to perform their tasks. so the Machine parts and Perishable Tooling need to be pretty robust. Of Course we inspect and calibrate inspection gages and such too.an example.This lever is made from two pieces of 5/8x 1 1/2" 1020 Bar Stock milled to shape then welded together, the annotation on the print was 1/8" full fillet weld. Sorry I can't show you the Actual print Vendor sent in this part. We do the inspections in my area.Margins show cold, ends show light penetration.this example was brought to me by an inspector to decypher the weldment callout. I explained the callout. then explained the inspection process and critique of the weld.Callout indicates a 1/8" fillet "all around"... looking at the pics... Ahem...This arm is only under several TONs of pressure... only about 40 or so...This is what the notation looks like on the print...Discuss...

Reply:Isn't the fillet sign backwards??

Reply:Well looks like the filet symbol is backwards and that weld looks like a lap joint. ^ not an expert.. Here is a guide to proper symbols.

Reply:Weld symbol is crap, obviously the draftsman does not know symbols. Not only that, how'd you get a fillett weld on the two lapped sides, you've got two fillett welds and two butt? welds.....Mike
Reply:time to find a new engineer to do the prints joint design  would not dictate a all around fillet  but two different weld call outs one for the fillets other for the butt (i would design that to be a groove weld on the sides ) to get penon the fillets the welder did there was not enough heat input to get proper wetting in of the toes and appears there was no weld prep done prior to welding find a new welder or train the one you haveLast edited by WeldorWes; 06-19-2013 at 03:59 AM.Miller Xmt 350Lincoln Ln-25Ahp 200xSmith Gas Mixer AR/HTig is my Kung FuThrowing down dimes and weaving aboutInstagram http://instagram.com/[email protected]
Reply:I can't read welding symbols, but who in their right mind would think that that was an acceptable means of metallurgically joining two pieces that thick?  I'd want a bevel on each piece and a really hot weld between.I'd be embarrassed to submit that as my work.TA Arcmaster 300CM3XMT 304S22P12 suitcase feederX-Treme 12VSOptima pulserTA161SMaxstar 150STLHypertherm PM45OP setupStihl 020AVP, 039, 066 Magnum

Reply:Actual Annotation from the print, I messed up in my artists rendition, the fillet flag directions is not terribly important anyway. but here is how it is on the actual print.
Reply:Weld symbol looks correct, but the extra fillet symbol is redundant. However the sample weld is not to print. It is not "all around".I would point that out to the engineer. Certainly that weld is not safe. Looks too cold as well as not all around.Weld like a "WELDOR", not a wel-"DERR" MillerDynasty700DX,Dynasty350DX4ea,Dynasty200DX,Li  ncolnSW200-2ea.,MillerMatic350P,MillerMatic200w/spoolgun,MKCobraMig260,Lincoln SP-170T,PlasmaCam/Hypertherm1250,HFProTig2ea,MigMax1ea.
Reply:The end of the weld really is not an indicator of penetration.  There's less material there, nothing to soak up the heat.  So a poor penetrating weld (along it's ENTIRE LENGTH) can look "good" at the end while being poor in penetration."Any day above ground is a good day"http://www.farmersamm.com/
Reply:Weld = fail Not to print/drawing, and welds look 'cold'.About the drawing and symbol,  the drawing clearly has a weld-all-around symbol on it, and no matter how you look at it, the submitted part is not welded all around.Now as to the actual weld symbol(s) that 'should' be there, that's a little trickier.The lap joint calling out for a fillet weld is 'correct', but you can't put a fillet weld on an 'edge' (the 'side' of the two plates with their edges even).So, to me, the drawing is not only a bit unclear about what is desired, but actually a bit contradictory in the weld call-out.If the desired weldment is supposed to have just the two fillet welds on the lap-joint area, the drawing should have the double fillet weld symbols (arrow-side and other-side) and NOT have the weld all around symbol.If the desired weldment actually -is- supposed to be welded all around, then the drawing should call out the fillet welds but without the weld-all-around symbol and then have another weld call out (in the 'side' view) with either edge welds called out or groove welds called out.And depending on exactly how the weldment is install/used/loaded, those 1/8 inch welds holding the 5/8 inch thick chunks together may or may not be 'adequate'.  But to me, unless the welds are pretty much just there to hold the weldment together for 'handling' and the nice big hole (bolt or pin goes in the hole??) is sort of what holds it all together when actually installed/used, calling out 1/8 inch fillet welds on some beefy 5/8 inch thick plate chunks is 'iffy'.But that is up to Engineering to determine and clarify and 'fix' the drawing as needed.  The best laid schemes ...

Reply:Let us know what the engineer decides.
Reply:Area bought the parts regardless and sent to our in house shop for re-work...Vendor got a "Ding" for the Non Conformance. This vendor has a STACK of them...The Bolt/Pin that goes in the big hole is a pivot not a way to HOLD the part together.I sent my critique of the welding job to the vendor and the gaining engineer...and the Quality Engineer, whom I had to explain what "Brazing" was and Explain what I meant by Cold on the toes of the weld.. and Poor Penetration...The print also calls for a "Case" hardening on the "working" end of the partThere was no evidence of the case hardening process no discoloration no evidence of anything but standard material. The Engineer has told me in the past not to TEST for case...Just take the vendor at their word... He came in today with a whole PILE of parts that have callouts of 60-64Rc that tested less than 10... some were single digits... they had redrawn the prints and didn't put the hardness on the new prints! So now they received what they asked for DEAD SOFT....

Reply:No certs were included with the parts, the manufacturing engineers changed the prints without running them through the proper process and the buyers sent the screwed up prints to several vendors.... GREAT! We go through this process all the time.We had 5 gaskets pass through today roughly 1/16 inch cork, 3/8 inch wide in a very squared rectangular U shape with 4 holes... these gaskets could have been made by someone with a razor knife, in less than one hour for all 5...  costing $70 EACH, a single had been purchased a month ago for $270... I am CLEARLY in the wrong line of work!
