If you are a new or beginner welder, watch this video to learn about the three most common welding processes — MIG, stick and TIG — including the advantages and disadvantages of each, when it’s best to use each and what material can be used.

Welding is the liquefaction of base metals with heat to fuse them together. There are three basic elements: heat source, filler metal and the shielding gas or flux. The three most common types of welding processes are MIG, stick and TIG. MIG welding is the most common type of welding and it is easier to learn, much cleaner than stick welding and can be used on a variety of material thicknesses. Stick welding is a flux process, so is better suited for outdoor use and with thicker or dirty materials. TIG welding provides the highest quality weld, both cleaner and more esthetically pleasing.

  1. Wait…straight to the point, explained everything he said he would, was easy to understand and I actually learned something..something seems off. Not like the rest of the videos about welding.

  5. Thanks for the great video… I am learning from scratch… Here are my notes… Got a couple of question marks in there…
    Welding – Liquification of a Base Metal with Heat and then they fuse together.

    3 Common Characteristics

    1. Heat Source

    2. Filler Metal

    3. Shielding Gas or Flux

    3 Types:

    1. MIG

    a. Parts

    i. Heat – ?

    ii. Filler – Electrode on a spool of wire

    iii. Uses Shielding Gas

    b. Benefits

    i. Easier to learn because you preset all your parameters

    ii. Much cleaner welds because you don't have any slag process

    iii. Can be done with a wide variety of metal thicknesses

    iv. Good for in a garage or shop

    c. Weldable metals

    i. Steel

    ii. Stainless steel

    iii. Aluminum

    2. Stick

    a. Parts

    i. Heat – ?

    ii. Filler – ?

    iii. Uses Flux

    b. Benefits

    i. Can be done outside

    ii. Wind does not effect it as much

    iii. Works well on thicker metals

    iv. More forgiving when welding dirty or rusty metal

    v. Great for welding farm equipment

    vi. Great for welding gates in your driveway

    c. Drawbacks

    i. Produces a lot of spatter, vapor and fumes

    ii. Welds are not as clean

    d. Weldable metals

    i. Steel

    ii. Stainless steel

    iii. Cast iron

    3. TIG

    a. Parts

    i. Heat – ?

    ii. Filler – Metal

    iii. Gas or Flux – ?

    b. Benefits

    i. Provides highest quality and precise welds

    ii. More pleasing to look at the resulting weld beads

    iii. Works great on thin metals

    iv. Work on frames like for motorcycles, automobiles, sheet metal

    c. Drawbacks

    i. Difficult to control because you are controlling all three elements during the process

    1) Leg is controlling heat

    2) Off hand is controlling your filler metal deposition rate

    3) On hand controls non-consumable tungsten electrode that is creating your arc as you move through the bead

    ii. Slower process

    iii. Requires more skill and practice to master

    d. Weldable metals – any metal that can conduct electricity

    i. Steel

    ii. Stainless steel

    iii. Aluminum

    iv. Copper

    v. Brass

    vi. Chromoly

    vii. Exotic metals such as magnesium and titanium

    What you are going to be doing drives your choice of process.
