All About MIG, TIG, and Stick Welding
We at 3D Laser Fabrication INC offer MIG, TIG, and stick welding services. However, many
people do not know the difference between the three welding styles and what they are used for.
Let us explain it to you briefly.
MIG (Metal Inert Gas) welding was developed in the 1940s. It is considered semi-automated
because the MIG welding machine will keep welding without direct input from the welder.
MIG welders consist of a handle and a trigger that controls a wire feed. The wire feed feeds the
wire from a spool to a weld joint. The wire runs through the liner which has a gas feed through
the same cable to the point of arc. This protects the weld from the air.
MIG Welding requires three things, electricity (for heat), and electrode to fill the joint, and
shielding gas as protection from the air. The electrode in MIG welding is fed continuously. The
operator controls the amount of weld being done.

Automotive General Repairs
TIG (Tungsten Inert Gas) welding is a manual welding process. It requires the welder to use two
hands to weld. In TIG welding, one hand is used for holding the TIG torch that produces arc. The
other hand is used to add filler metal to weld the joint. TIG welding is the most difficult welding
style to learn because it requires the use of two hands, but it is used with a wider variety of metal
types. TIG welding is slow, but produces a higher quality weld.

Stick (Shielded Metal Arc) welding is the easiest form of welding to learn and is more widely
used due to its versatility. It is a manual arc welding process that uses a consumable electrode
covered with a flux in order to lay the weld. An alternating or direct current from a power supply
is used to for the electric arc between the electrode and the metals being joined. The flux coating
of the electrode disintegrates as the weld is laid. This gives off vapors that serve as the weld
protecting shielding gas as the joint cools.
