welding
rod, or
welding
electrode, are metal rods that melt and become part of the strong bond that
holds metal together. They come in a wide variety of sizes and metals. The metal
is surrounded by "flux," which prevents oxidation of the metal being welded.
Choosing the right kind for your job is very important because the wrong kind
can weaken the weld.
The first two digits of the welding rod number
indicate the strength of the weld. Multiply the 60 in 6010, for instance, to get
60,000 pounds of pulling force.
6010 This is a very common type of
welding rod. It is used for farm equipment, piping, wrought iron, and many kinds
of general maintenance. The rod must be run on welders that use Direct Current
(DC).
7018 This is a very versatile type of welding electrode and is a
little easier to use than 6010. It's a low-hydrogen rod and moisture can't be
allowed to get into the flux. A "rod oven" should be used to store 7018 at 250
degrees.
308L AC/DC This rod is used to weld stainless steel and is
resistant to cracks and corrosion. It also works well in all welding
positions.
24 AC/DC This rod is used to join two different kinds of metal
and works in all positions.
