MIG (Metal Inert Gas) and GMAW (Gas Metal Arc Welding), are two widely used welding processes that combine a continuous feed of welding wire with shielding gas.
These processes can be classified in:
Standard MIG
In standard MIG welding, a solid wire electrode is continuously fed through a welding gun and into the weld pool.
Standard MIG leads to high heat input, it is then typically used on thick materials, when high travel speeds and low wire feed speeds are used.
Pulse MIG
Pulse MIG welding alternates between high and low current levels, creating a pulsing effect.
This process enhances control over heat input, making it particularly useful for thin materials, when low travel speeds and high wire feed speeds are used.
