Key benefits of MIG welding

The MIG/MAG process has a number of features and benefits over other modes especially if the correct method is used.

  • It can weld most commercial metals and alloys including steel, aluminium and stainless steel.


  • The simple techniques are easy to learn as the constant feeding of the consumable wire allows the operator to concentrate on the arc control.


  • It can be easily mechanised for repetitive welding.


  • The process allows for greater speed and efficiency compared to the MMA and TIG process resulting in faster welding with reduced labour costs.


  • It can be used in almost all positions.


  • A wide range of current can be used for a single wire diameter allowing a variety of joints to be made without changing consumable or equipment.


  • Continuously fed consumable wire reduces down time due to changeover.


  • The process is a “low hydrogen” process with reduced danger of hydrogen pick up.


  • Alloy steels are weldable with less risk of cold cracking and no special treatment of the consumables is required such as drying ovens.


  • Less weld defects caused by stop starts in the weld time.


  • Approximately 98% of the consumable wire is converted to weld material compared to 65% with MMA welding.


  • Produces little or no slag (weld shield formation) helping reduce weld defects such as slag inclusion.


  • The arc pool is clearly visible during welding.


  • There is low wastage with the MIG/MAG process compared to MMA and minimal post weld clean up required saving time and reducing labour cost.
