MIG Welding

Metal Inert Gas (MIG) welding is a common method of welding where an electric arc forms between the wire electrode, which is shielded from the access of air by an inert gas, and the metal work-piece, heating the metal(s) to the point of melting and joining.

A consumable wire, used as the electrode, is continually fed from a spool when MIG welding. A fine intense arc will generate between the electrode and work material, producing enough heat to melt the electrode and the base metal; resulting in a highly efficient process, producing high-quality welds with minimal heat distortion.

MIG welding is best suited for the fabrication of sheet metal and generally all available metals can be welded through this process. This process may also be used for deep groove welding.

Advantages of choosing MIG Welding:

  • More efficient
  • Greater deposition rates
  • No slag formation
  • Cleaner, better quality welds
  • Can weld almost all metals
  • Minimised weld defects
  • Ultra-low hydrogen process

TIG Welding

Tungsten Inert Gas (TIG) welding is an alternative to MIG welding and is more commonly used to weld finer materials such as aluminium, copper alloys, thin stainless steel, or other light materials. Although less efficient than MIG welding, it allows for enhanced control while still creating strong welds.

The heat from the high-intensity arc produced melt the base metals to form a welding joint. The TIG process may or may not require a filler metal. No filler metal is required for welding thin material; however, thick joints may require some filler material. Used in the form of rods, the filler metal is fed manually by the welder into the welding zone.

TIG welding is most often used to weld aluminium and aluminium alloys. Other commonly used metals include stainless steel, carbon base alloy, copper base alloy, nickel base alloy etc; it is also used to welding dissimilar metals. The TIG welding process is commonly used in aerospace industries for numerous reasons, including Distortion Control, Interpass Cleaning and Porosity & Side Wall Fusion.

Advantages of choosing TIG Welding:

  • Superior quality weld beads
  • Inherent corrosion resistance
  • Welds can be made with or without filler metal
  • Precise control of welding variables
  • Clean weld areas, free of spatter
  • Lower heat affected zone and metal distortion
  • Can weld almost all metals
