MIG vs TIG vs Stick Welding

When it comes to welding, the type of welding you choose can make all the difference. The three most common types of welding are MIG, TIG, and Stick Welding. Each type of welding has its advantages, downsides, and applications. Regardless of your welding experience, understanding these methods is crucial for successful welds in different applicable situations.

What is MIG Welding? (Metal Inert Gas)

MIG welding is a semi-automatic process where both the electrode and filler metal are continuously fed. An electric arc melts the wire being fed through the torch which forms strong bonds.

Key Benefits and Features of MIG Welding:

Ease of use: MIG welding is ideal for beginners, and comparatively has an easier set-up and operation.
Speed: The quicker set-up process and faster welding method, make it great for productivity.
Versatility: Suitable for thin and thick materials such as steel and aluminium (with a spool gun).
Limitations: Sensitive to environmental conditions unless using a flux-cored wire.

Applications for MIG Welding include car panels, trailers, frames, and general fabrication. MIG is the perfect welding type for hobbyists and DIY projects.

TIG Welding (Tungsten Inert Gas)

TIG Welding uses a non-consumable tungsten electrode to create an arc, with the filler rod being fed into the heat to create a weld pool. TIG welding is known for its precision and quality but is the most difficult method out of the main three, which requires skill and patience.

Key features and benefits of TIG Welding:

Precision: TIG welding is best for fabrication projects that require thin materials, or complex welds.
Versatility: TIG welding works with various metals, including aluminium and stainless steel.
Challenges: Requires practice, patience, and skill as it involves many adjustable settings and requires stability.

Applications: Automotive work, artistic welding, and projects that need to be aesthetically pleasing

Stick Welding (Manual Metal Arc Welding)

Stick welding involves using a flux-coated electrode to create an arc and melt the piece. The arc melts both the electrode and the workpiece, which fuses them to form the weld. The flux coating on the electrode provides a shield to protect the weld from the atmosphere and forms a layer of slag that must be removed after welding is complete to showcase the clean weld beneath.

Key features of Stick Welding:

Durability: Excellent for thick materials and structural work
Portability: Minimal equipment is needed and is easy to transport for on-site jobs or travel jobs
Limitations: Not suitable for thing material or aluminium and requires cleaning up after welding.

Applications: Construction, structural fabrication, and outdoor projects.
