In addition to the equipment used in arc welding, various types
of electrodes, rods, wires, fluxes, and gases are also used. These
are called "consumables" because they are consumed or "used up"
during welding. All filler metals whether supplied by a covered
electrode, a rod, or a wire are "consumed" during welding and become
a part of the finished weldment. All shielding gases used with a
gas-shielded arc-welding process such as MIG welding or TIG welding
are expended during welding. Similarly, granular fluxes such as
used with the submerged arc (SAW) process are at least partially
expended during welding.
Stick electrodes used in the manual stick welding (SMAW) process
consist of a filler metal and coating. The coating has many functions,
including the creation of shielding gases under the heat of the
arc. Self-shielded flux-cored wires are essentially a continuous
stick electrode turned "outside-in" for use in semiautomatic welding.
Cored wires typically consist of a steel tube filled with the necessary
ingredients for shielding the arc and other functions.
A number of welding consumables do not produce their own shielding
gas, but rely on an external source for this function. Common external
shielding gases include carbon dioxide (CO2) and various mixes of argon
and helium. The MIG welding process (GMAW) utilizes a solid wire
electrode and external shielding gas. Similarly, metal-cored wires
and gas-shielded, flux-cored (FCAW-GS) wires need an external
shielding gas too. The TIG welding process (GTAW)
also requires an external shielding gas. The TIG welding application
may or may not warrant a manually fed filler metal.
In the submerged arc process (SAW) a continuous wire electrode -
solid or cored - and flux are used. Flux is a granular material
that is metered into the weld zone by gravity flow through a nozzle.

| Lincoln Electric - The Leader in
Welding Consumables
We're very fussy about the arc welding consumables
that carry the Lincoln brand name. In fact, our consumables are
the most thoroughly tested welding consumables in the industry.
We check raw materials for up to 30 chemical elements, monitor electrode
diameter and flux mixtures several times during the manufacturing
process and examine the appropriate coating or surface conditioning
using a variety of proprietary technologies.
Why do we go to all this trouble? Two reasons: First, we don't want
to just meet the outside limits of AWS or other industry specifications
- we want to nail it to assure you will always be within required
specifications. In other words, you will get what you pay for!
More importantly, we want to deliver the most consistent performance
- performance you can rely on inch by inch within a package, or
from package to package, or from pallet to pallet. After all, your
reputation - and ours - depends on it.
