Hello all

I know this topic is completely unrelated to ISO or QMS, but we all have such a wealth on information, I hope someone can point me in the right direction.

I am looking for some information on stud welding. Ya know, just enough to become dangerous…LOL.

Anyone know of any good web sites?

Thanks,
CarolX

Don't go there

:biglaugh:

Jim

Don't go there

OMG and LOL.....my head is so full of useless web info (I have been surfing for a couple of hours), I didn't even really read my post from an outside point of view....

:biglaugh:

I'm gonna stay out of this one. :thedeal:

I'M GONA STAY OUT OF THIS ONE


Think I have it covered Marc - due to legnth of explainations etc. I sent Carol a "private message" - outlining all the variables surrounding "studs" and the welding thereof ;)

Best info can be obtained through AWS.

Emhart Fastening Teknologies make and sell weld studs.

Hope this helps.


Geoff.

Take a look at the Tucker, Warren and Gripco products at

Jim,

Thanks for the info. I need to review more of the AWS material, but a great resource!

Geoff,

Thanks for the addy's, will reivew these sites today for info.


Marc,

I'm gonna stay out of this one.

u a BAD boy!!! LOL

Have a great day all!

Hey Carol...

If you get the "stud welding" figured out, please let me know:lick:

It's not fair to keep that information away from the other females of the forum :biglaugh:

And behind our backs! We all want to know about Stud Welding, too! Or, at least, what did you tell HER????

Well - not hiding info mind ya (especially from the female population in the group) but will attempt to type this out as proffesionally as possible without it reading real BAAAAADDDD!!;)

The variables we talked about were - How Clean the Mating stock was at each joint and the point of contact equipment condition (often any type of moisture/oil/dust/dirt in a weld joint or on the weld nozzles can cause problems)

Also the electrical power inputs and "cover gas mediums" used in the process can be a major variable ... if not in an air-flow shielded environment. :eek:

Best information for voltage/thickness settings can be researched at the American Welding Society website. I believe its http://www.aws.org/

The stregnth of contact/cleanlieness and position of Grounding the weld piece can also play a part in lack of fusion. (improper position and weak ground connections can cause what is termed "Arc Blow" - :ko: that seldom occurs with newer weld processes - but can happen even with a mig weld setup. (its a magnetic pattern thing - I'll not try to explain here.)

Last I heard from Carol they had a tech- rep in and discovered what was termed as "cold plunge" on 2 of 4 - 8/32" studs welded to 16 gage sheet.... The failure rate was 50%

A bit of fixturing - updates and changes have at least improved the 50% failure rate but I don't know by how much at this point.


Now hopefully everyone has an idea at least of the end result
;)

Possibly Carol can give us details on what physical changes were made to the holding fixture to resolve ???

A site not to visit,

www.stud.com :bigwave:

You guys are BAD!!!!!!!

I can think of a few other things I might inject here.....but.....grrrrr, I digress.....LOL


Ok - I will try to muddle through this update best I can. I am learning as I go, as we do a minimal amount of stud welding. Apparently, we were loosing current because our positioning fixture holes were too small, causing minor arcing, and preventing proper fusion of the material. We changed collars (I think this is the right term), corrected our positioning fixture, and we now have no failures (we love testing for failures!!!)

Jim - I hope this decribes the solution. I am out of the office today (2 sick kids home from school), so I don't have my notes.

Thanks again for all your help.

And to the rest of you

:eek: LOL

Regards,
CarolX

Be prepare for some more "off color" responses!!!!!!!!!!!!!!!

Have a great day, this is one of the more interesting topics that have come up in a long time.

Just remember that a stud has a short life span if not properly conditioned with some type of heating element.

Al, part of your mind is in the gutter. I mean, honestly.

Jim and Carol, thanks for the specifics. In all honesty I do like the specifics in the posts as much as possible, That's how we all learn here. Sometimes we see something like this and later run into a similar situation and - Bingo! I remember where we were discussing.... The more details (within what you feel comfortable saying with consideration to possible company proprietary info) the better. :thedeal:

Details? Yes, please. Always.

Thanks for the update Carol !!

Marc - I agree & hope the details help...

Reality is that - many of the "technical terms" used in welding practices can be interpreted in a number of ways... many of which can be seen as very humorus.. if one is in that particular mode...

(Al - to clarify - that's not saying that the humor isn't appreciated from time to time ;)

Too much fun to keep it private. I've already sold the rights to this thread to Oprah.

Marc: I'm assuming you were referring to my first draft explaination of a "one-time private affair message" :biglaugh:

Maybe we should stay from explaining the various types of Stud - Forms? (I don't think I could even make Oprah understand) :lick:

And to think yesterday I spent almost an hour talking with a client about his horses and his Stud Farm.

Marc,

I do take some umbridge to the comment!

In my career I have come to know that certain types on products need some type of heat treating. I am not a "proffesional" in the heat treating field but I do know some of the basics.

I did not start the topic, and quite a few members, including you started the somewhat lewd responses. i.e. "I won't touch that comment"

The first part of my post just warned that it could lead to some "off color" comments. The second part of my post was a real response.


To Carol, my response was real!l

I'm kidding with you, Al. Take a Zanax. Or let me know and I'll send you a couple of Valium. I've got a whole bunch left over from August-September that I don't 'need' any more.

Carol,
(we love testing for failures!!!) AAAHHHH Yes. Reminds me of when I was worked in the test cell at a hydraulics manufacturer. There is nothing quite like the smell of hot oil dripping off the walls Or ceiling panels kicked out of place because a stud weld failed and blew the fitting off. (the oil would drip out of the ceiling for weeks)

I have so many fond memories. It's a great job to get paid to try to break things.

Yes Carol, we love testing for failures.

My Man! I'll be right over:smokin:

Well, the doc gave me a script for 10mg tid for a month with refills 6x and said if I used them all he'd have me committed. He's been my doc since the early 1970's and I'm afraid he was half serious. Of course, this was all energy's fault in the first place :rolleyes:

So - I filled the original script which was like 90 10mg tablets and I have about 20 of those left with 5 refills left. All they do to me is make me kinda sleepy. I guess that's good when you're stressed out. Worked for me.

Marc,

I never over respond to anything and stand by my statement, you are an overbearing slave driver that whips into us into submissioin,
:biglaugh: (yes, just kidding)


I am not an overbearing sexist, just an old man that enjoys the talk and to respond to people..

To anybody that take my posts as an insult I apologize and please contact me!


Alistair S, Dyer

Hey Al,

No offense taken here, in fact...thanks for lightening up the subject!!!!!!! I just finished a disuccussion with our head engineer on terminology, and what may be PC, so to speak. Then reading through this thread, I'm laughing so hard the tears are about to roll down my face!

Have a good one

> To anybody that take my posts as an insult I apologize

I don't think anyone is going to faint over the thread so far. No complaint here. There is a 'Report This Post' link at the botom of every post so if someone is offended the can use that link. Until then, on with the show.

> I am not an overbearing sexist

Yes you are. All of us men are. Even the ones who lie and say they aren't...

Marc,

You got me on the last one, I sure can't argue that men are sexist pigs. I guess some of us just hide it better. Promise not to tell my wives!
