Talk:Plasma arc welding

Image Inclusion
I've never seen Plasma weldong before - Plasma cutting, but not welding. I think an image would spruce this up quite a bit :-)

Plasma gas?
Isn't that like saying a "solid liquid?" AFAIK, plasma is considered a phase of matter distinct from gas, but IANA physicist... Anyone better-educated care to throw in their 2¢? El Mariachi 09:48, 18 May 2006 (UTC)
 * You're right, but I'm not sure off the top of my head if "plasma" here is used in the scientific sense. It might just be the name.  I'll look into it. --Spangineer[es]  (háblame)  12:14, 18 May 2006 (UTC)

I've found a lot of information on how plasma is defined (basically an ionized gas), but can't seem to find what the gas is made from, for plasma welding/cutting. For neon lights and plasma TVs, it appears to be neon. What is used for plasma welding/cutting? Perhaps this could be put on the Page. Or did I miss it? Thanks, neon is used in plasma arc welding for neon lights - RedKnight7 14:32, 23 March 2007 (UTC)

Orifice Diameter
The article refers to

Micro-plasma (< 15 A)

Melt-in mode (15–400 A)

Keyhole mode (>100 A)

Is the "A" here meant to be the Angstrom symbol, " &#197; "? If so, the character code is &#38;&#35;197&#59;. I'd make the changes myself, but for all I know the "A" is some arcane term from the welding field and should stay just as it is.

 * A stands for Ampere, the current intensity unit.Whistopathe 00:32, 14 January 2007 (UTC)


 * Thanks. I've updated the page, and can now stop watching it.

Obvious Impossibility
In the beginning of this article it states that material of at least a half inch is weldable then states later on that only material of 1/4 or.25 inch is weldable which one is it more research needs to be done before the information is allowed to be here for extended periods of time oh and plasma ges for cutting or welding can be made of any gas and is routinelymade with pressurised air and an arc of electricity —Preceding unsigned comment added by 216.15.109.64 (talk) 03:25, 7 November 2009 (UTC)


 * Good catch. I've fixed it. Wizard191 (talk) 22:59, 9 November 2009 (UTC)

Needs comparative info
It's great that this article is here. Thanks.

I can see some room for improvement. Simply because I, for one, would like to learn more. How about discussing when PAW would be the method of choice?

Part of such a discussion might be a comparison with other technologies - stick, wire-feed, GMAW, and oxy-fuel being some that come to mind. Comparison of aspects like quality of the welds. Very thin or thick metal. Ease or difficulty of use. Ease or difficulty of learning to use it. General cost considerations of equipment and supplies.

On The Potential Page Subsection Addition and/or Separate Page Creation on Plasma Arc Gouging

 * I am currently in Welding School, so not an expert, but just in looking up various things i hear/see i came across Plasma Arc Gouging which is supposedly different than Plasma Cutting although it is a bit of a Fuzzy Concept
 * Here is a related link i found:
 * An Article by "Fabricating and Metalworking" Titled "CHOOSING A GOUGING METHOD"
 * Accesed it at this time/version (Made it myself with the Chrome Extension)
 * I need to learn proper *formatting* too for all that i guess!
 * I can do a more in-depth search later, but am moving on until i get some feedback on all this. I would also LOVE to speak with an expert.  I'll ask around at welding school, although i think Plasma Arc Gouging may be more novel/niche and thus not something they would know much about?
