Welding Rods Applications
welding needs, for both individual and commercial use, can be met by using a fewcommon
welding rods. Listed below is a question about a welding machine and short descriptions
of the characteristics and applications of five welding rods.
welding machine should I use?
an "all around general use" welding machine consider this: A machine
with AC/DC output works well on most jobs but a DC machine, or a DC setting, for
stick welding has more advantages over an AC machine. Use a 220 v, 40-225 amps
and up, DC machine or setting because it offers easier starts, less sticking and
spatter, stronger and better looking welds, in all positions.
are the best welding rods to use for general or "all purpose" work on
regular or mild steel?
6010 for DC, 6011 for AC or DC. 6013 can also be used for DC or AC but it has
less penetration than 6010 and delivers a better appearing weld. Use 6013 on lighter
sheet metal and use 7018 low-hydrogen rods, (low-hy), for almost any use. Use
7024 for higher depositions in flat or horizontal positions.
welding rods penetrate deeply but have high spatter. They are good for all positions,
all types of steel, and almost any conditions and use DC current. (For better
penetration on thicker steel over 3/8," bevel the edges and create a gap
of about 1/8" wide; use 6010 for tack up and a root pass and weld the remaining
passes and the "cap pass" with 7018.) 6010 welding rods need to be stored
in a dry location, at room temperature, and in a sealed container.
welding rods have all the characteristics of 6010, are used in all positions with
AC or DC current, and work well on all types of regular or mild steel.
has all the characteristics of 6010 but can be used with AC or DC current; it
has less penetration and delivers a better-looking weld. Use 6013 on light sheet
metal up to 3/16."
7018 low-hy, low penetration, on all positions, with AC or DC current. Use the
highest amp setting as practical. Use a straightforward "drag" progression
with a "short arc." The low moisture make-up of this welding rod reduces
chemical reactions in the weld itself and makes for the highest quality x-ray
perfect welds. (Note - this electrode must be kept dry. If it's exposed to humid
air or gets damp it must be dried in a rod oven before use. See Welding
Rods Storage chart.)
7024 high deposition welding rods for flat and horizontal positions. It's "easy"
to use because its thick flux automatically maintains the correct arc length,
which allows you to "drag" the rod.
general, when working with steel plate or higher strength steel or pipe, you will
get a better weld appearance by tacking-up and running a root pass with 6010 on
DC current or setting, and then using low-hy 7018 rod on the remanding passes.
days of keeping welding rods in an old refrigerator under a 100-watt light bulb
are gone. The welding rods of "today" are really "high tech"
and "space aged." They need proper storing and maintenance. Always check
with the manufacture recommendations for use. It's easy, it's fast, and it doesn't
cost a dime to do this. All welding rod manufactures are on line. Just do a quick
search on Yahoo! and follow the suggestions of the manufacturer.
