anyone have any info on hammer welding? Suppafly 03:43, 11 Nov 2004 (UTC)
which kind came first and when was it invented? Aaronbrick 23:22, 4 Dec 2004 (UTC)
On the tv program Rough Science, they made what was basically thermite, out of a ground up aluminum can and rust from a shed as an oxygen source. The maker commented that this method has be used to weld railroad joints before. Anyone have any more info? --63.206.116.16 04:29, 31 May 2005 (UTC)
Shot welding
There is a stub on shot welding that isn't referenced here. The description makes it appear like a synonym for spot welding. Could somebody knowledgeable look into this? —Naddy 12:46, 23 Mar 2005 (UTC)
- Sure thing – I'm doing a bunch of research on this topic, though I will say that I've never heard of shot welding. It may be another name for another resistance welding process, like you suggested. I'll see what I can find. --Spangineer ∞ 13:35, Mar 23, 2005 (UTC)
- The article was likely stubbed as a result of featuring my Pioneer Zephyr article on the front page today. I've copied the patent reference over to the article and merged shotwelding and shotweld into the latter name. The patent text describes the difference between shotwelding and spot welding. slambo 16:30, Mar 23, 2005 (UTC)
- Well, I looked at the article and a little bit at the patent description, and all I see is a type of spot welding. Obviously, I need to study it more, but it looks like it's just a method of spot welding that is used on stainless steel. From my point of view, that means that the sentence "The train's construction included innovations such as shotwelding (not to be confused with spot welding) to join the stainless steel" on Pioneer Zephyr should actually be "The train's construction included innovations such as shotwelding (a specialized spot welding method) to join the stainless steel", and that the relation between the two should be better clarified in the shotwelding article.

TIG Weld image
(posted by TTLightningRod) --Spangineer ∞ 19:12, May 15, 2005 (UTC)
Regarding the images that I'm looking for: I guess you could call them line drawings of the individual processes, such as SMA welding and GTA welding, as well as the torches used in GTA welding or Plasma arc welding. I'm not sure how easy that would be to do on CAD... I've done some work in CAD before as well and I tend to think that simply using drawing software would be easier. But my skills in that are limited – so far I've just done the uncomplicated joint design and HAZ images. Now, however, I'm not sure that those will be necessary for the welding article, since we a few more images of the processes used were just added. For the articles the individual processes, however, line drawings would be really useful.
Thanks for that picture of a fillet joint – we just have to figure out where to insert it. I'm planning to do some serious updating to the joinery article so that it includes welding joints as well, and that image could certainly be added there. On this article however, since such a small area is devoted to joint design, I'm not sure if it will fit. If you disagree, we can work something out, but I feel like this is just a general summary of joint design and that the images in the geometry section are of the type we need. Let me know what you think. --Spangineer ∞ 19:12, May 15, 2005 (UTC)
- I choose to refrain from "strong opinion" as to what would be "best", so don't worry about having to debate that stuff out with me. Instead, I like to just put something (almost anything) in, and let time replace it with ever "better" imagery. CAD is not so tough, especially when I have a clear description of what someone wants, or what I want to illustrate. We could also just take real photos of the items you want. "TIG Torch", "Stick Electrode, in holder", "Wire Feed torch expelling wire"... things like that? Let me know... I'll put my boots on, and go out to the shop with my camera. TTLightningRod 19:35, 15 May 2005 (UTC)
- The benefit of line drawings is that you can "see" the inside of things like TIG torches that are otherwise quite mysterious, since you can't take a cross-section image with a camera. Still, photographs are awesome, and clear pictures of the torches used in all those processes would be great. We are in definite need of good pictures on the individual welding process pages. I'd love to see wikipedia become a much better source for manufacturing information. --Spangineer ∞ 21:02, May 16, 2005 (UTC)
- A richer source for manufacturing information... you got that right. That will be fantastic. As for CAD, rendering with "cut away" or cross-sectioning can speak volumes. Clear photos too. I would ask that you get this started by deciding on a first image you most want. Define the items you want to point out, and any actions. You might be surprised with the speed and resulting illustration. But I would ask that you define the scope of this first part... I can get too carried away and waist time. TTLightningRod 16:32, 17 May 2005 (UTC)
- Thanks for the awesome offer! I was just looking over the GMAW article, and boy, does it need help. There's hardly anything there, and half of the info is inaccurate besides. And since we have no pictures of GMA welding anywhere, it would be awesome to get a clear picture of a welder performing the welding (perhaps out of position; ie, not flat/horizontal), and a cross-sectional view of the weld area and the torch - I'm thinking of something that shows the base metal, the already laid weld metal behind the torch, the gaseous shield around the welding arc, the three "tubes" in the torch (that is, the shielding gas tube, the solid electrode wire, and the current conductor), and the wire guide and contact tube (the part near the tip of the torch from which the electrode exits). I don't care so much about all the interworkings of how the tube and wires interact, but just so long as you can see them at the top of the torch, say, it would be great. How they all come together into the wire guide/contact tube doesn't really matter so much to me; go ahead and cover that up with the outside of the torch. Hopefully that's clear. Let me know if you have any questions, and of course, if you want to make any changes that you think might be helpful, go ahead.
- One more thing - when you upload these, please do so on the wikimedia commons – that way any of the wikipedia projects can use those images, and if someday I get around to putting all this info on the spanish wikipedia, it would be really helpful. Thanks again! --Spangineer ∞ 17:43, May 18, 2005 (UTC)
GMAW torch head, cut-away view
Congratulations on achieving Featured Article status.... Very cool. I'm doing some of my regular money making business today, however I should be able to do a roughed-out cut away GMAW that we can use to haggle over the details with. I should be able to work on that this evening, and if not, tomorrow then. I'll post the rough draft JPEG in the commons, and link here for comments. Talk to you soon....

oxy-acetylene gas???
Oxy-acetylene is not a gas, but a kind of torch that uses a mixture of gases. You could say "oxy-acetylene torch" or process or even " oxy-acetylene welding", but strictly speaking, not " oxy-acetylene gas". I am also surprised that robotic welding is called "robot welding," which might better mean the welding of parts to make robots, but I guess if that is the term used in the trade, it has to be used.
Also in the first diagram you are intending to put in place you have two different spellings in the same picture: "electrafied" and "electrified" - the latter being the correct one. Better fix it before displaying it.
Also, simultaneously, at the same time you write "also flows simultaneously" which is redundant - "simultaneously" is enough already.
Also you have used the word "effect" instead of "affect" in "adversely effect the work piece" and I *think* you mean "workpiece" not "work piece". "Workpiece" is in Merriam Webster~ and I really think it is more appropriate. Pdn
- Good points - first, regarding oxy-acetylene, I changed the lead to say "oxygen-acetylene gas mixture", since according to what I've read, those torches use a mixture of the gases to create the flame (it's acetylene burning in oxygen). I agree with you on robot welding, but based on what I've read, I believe that robot welding is the more commonly used term. I'll check my sources to verify that soon. As for the diagrams, the text is going to be converted to numbers for easier captioning, so we'll take care of the errors you pointed out. Thanks for that. --Spangineer ∞ 14:45, May 31, 2005 (UTC)
- Strictly speaking, is not the source of the energy in gas welding the combustion of acetylene in oxygen? They are both required for combustion to take place, and thus, the mixture of the two is what provides the energy for welding. That's what I'm trying to say in the lead of the article. Do you disagree? --Spangineer ∞ 16:52, Jun 1, 2005 (UTC)
forgive the delay

Let's discuss how the images and text can be made more effective.
- Please use these illustrations to create translatable numbered list tables for the identified parts. If people find these type of images useful, please let me know where else they would be desired. They are rather simple to create, and it would seem that engineering and drafting students may find that their school projects could have a useful home here in the wiki, instead of just being forgotten after the graded class. TTLightningRod 12:40, 1 Jun 2005 (UTC)
- Although the actual images have been replaced by revisions, (click the image) the thumbnails do not seem to update immediately... however, placing the image link in a new ___location, brings the latest version into view. TTLightningRod 12:56, 1 Jun 2005 (UTC)
Delhi iron pillar
Why is there an image of the Delhi iron pillar on this page? It doesn't appear to be referred to in the text at all, and has little to do with welding.
- The history section was cut significantly and that mention was part of what was removed. I have restored the history section that was there several hours ago, and hope that any future desires to condense that section are first discussed here. --Spangineer ∞ 23:41, May 31, 2005 (UTC)
Request for editing
Second line in the History section: " Welding was used in practical in welding until about 1900, when a suitable blowtorch was developed." Any ideas what the author may have intended? I would think fire, but I'm not about to guess the intent. Hard to believe that got approved to the main page.
- Unfortunately, someone attempted to drastically shorten the history section and it wasn't immediately caught, so for several hours yesterday the history section was in disrepair. It's back to normal now. --Spangineer ∞ 11:31, Jun 1, 2005 (UTC)
Wikimania writing contest grand prize
This article won the overall Grand Prize for the Wikimania writing contest, as well as the Natural science & Technology category. Congratulations! Spangineer, if you would be so kind as to drop me a line, I'll see about transferring over the big bag of wiki you've won. +sj + 22:57, 21 August 2005 (UTC)
- For those of you not watching the awards ceremony, said back is 2'x1'x6" with a massive "Wiki" on each side (thanks, Webzen), and riddled with goodness.
