About Robotic TIG Welding

Tungsten inert gas welding is a process that uses an electrical current to superheat metal alloys to partially melt them. The more resistant the metal is to the current, the faster it will reach its melting point so the weld can be completed. Unlike gas metal arc welding, the electrode used in TIG welding can be a non-consumable type.

Some advantages of TIG welding over MIG welding include:

  • Reduced cost for filler materials;
  • Less weld splatter when not using filler; and
  • Superior weld performance when joining smaller pieces of metal makes it easier to meet tight production tolerances.

Normally, GTAW welding is a bit more difficult to precisely control than GMAW welding. However, Marlin’s use of CNC robots allows Marlin’s production team to consistently perform delicate welds that require millisecond-precise timing.

About Robotic MIG Welding

Marlin’s robotic GMAW welding systems use a consumable metal wire electrode that acts as a filler material to help bond two pieces of metal. Because the electrode becomes a filler material, this welding process doesn’t have to melt the metals being joined to achieve a weld.

MIG welding is great for joining:

  • Larger pieces of metal;
  • Metals with extremely high melting points; and
  • Metals with high conductivity.

While weld splatter is always a concern when dealing with welds that use filler materials, Marlin Steel’s MIG robotic welding unit minimizes splatter through precise computer-controlled weld operations and secondary processing techniques to remove excess spatter.
