Talk:Shielded metal arc welding

message: It says "these face shields sense when the super-bright electric arc has begun and turn the liquid crystal glass dark a few nanoseconds later."
But switching speeds of liquid crystals are usually more in the millisecond time scale.
Of course for the welding application it doesn't have to be a problem, since the light from the arc will presumably not turn on in a nanosecond, but more gradually.

text: They can be, but I think that's a topic for welding power supply.  I haven't done much study of all of the various types of power supplies and thus haven't written an in depth article on that topic.  This article attempts to cover the basics of power supplies commonly used for SMAW, but I'll see if I can find anything in my sources about what you describe. --Spangineer (háblame) 16:18, 16 February 2006 (UTC)

message: The last paragraph of the Electrode section was changed from:
:Common electrodes include the E6010, a fast-freeze, all-position electrode with a minimum tensile strength of 60 ksi (410 MPa) which is operated using DCEP.  Its cousin E6011 is similar except that it is used with alternating current.  E7024 is a fast-fill electrode, used primarily to make flat or horizontal welds using AC, DCEN, or DCEP.  Examples of a fill-freeze electrodes are the E6012, E6013, and E7014, all of which provide a compromise between fast welding speeds and all-position welding.Lincoln Electric, 6.2-7–6.2-10

:Common electrodes include the E6010, a fast-freeze, all-position electrode with a minimum tensile strength of 60 ksi (410 MPa) which is operated using DCEP.  E6010 is primarily used for making the root pass when welding pipe.  Its cousin E6011 is similar except that it is used with alternating current.  E6011 is known for its strong penetration and tolerance of dirty and/or rusty metal.  E7018 is a low-hydrogen electrode used for high quality X-ray welds.  It can be used in all positions with either AC or DC current.  E7018 is also used when weld bead apeparance is a priority.   E7024 is a fast-fill electrode, used primarily to make flat or horizontal welds using AC, DCEN, or DCEP.  Examples of a fill-freeze electrodes are the E6012, E6013, and E7014, all of which provide a compromise between fast welding speeds and all-position welding.Lincoln Electric, 6.2-7–6.2-10  E8018 and E9018 are higher strength electrodes commonly used on medium to high alloy steels, such as boilers.
All the added statements need to be confirmed in published works before being included here (as per WP:V). I'll look into the material I have, but any help would be appreciated! --Spangineeres (háblame) 18:20, 23 October 2006 (UTC)
replies: text: I'll take a look in my books but the information is correct.  To not even mention 7018 is odd especially when lesser known/used electrodes are mentioned.  6011 and 7018 are among the most commonly used electrodues.  Pipe welds are typically done with a 6010 root pass and 7018 cap.  Boiler tube welds are now commonly tig'ed for the root past and finished with the appropriate stick electrode (7018, 8018, or 9018).  An picture of an electrode chart from Lincoln, or Miller/Hobart would not be a bad idea.  (ROBZZZ 15:20, 24 October 2006 (UTC)
