- It's time for a little Welding 101.
12:25
Welding is a fabrication process that uses intense heat
12:29
and pressure to melt and fuse metals together.
12:33
While it may sound simple,
12:34
there are several complex types of welding.
12:37
The four most common being MIG, TIG, stick and flux core.
12:42
MIG welding uses a wire fed through the weld gun
12:45
that acts both as an electrode conductor and filler metal,
12:48
first creating the spark, then melting to form the weld.
12:52
One of the easier processes to learn,
12:54
MIG is popular with beginner welders.
12:57
An efficient way to weld metals of varying thicknesses,
13:01
MIG is widely used in the manufacturing
13:03
and construction industries.
13:05
While MIG relies on an ongoing wire feed,
13:09
TIG welding uses a non-consumable tungsten electrode
13:13
to heat welding rods that are placed by hand
13:15
in a pool of molten metal to fuse two metals together.
13:20
Often considered one of the most challenging methods
13:22
to master, TIG welding requires a great deal of skill
13:26
and finesse to produce the precise and detailed work
13:30
often found in aerospace, automotive,
13:33
and construction industries.
