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.
