Welding consumables - Wire electrodes and weld deposits for gas shielded metal arc welding of non alloy and fine grain steels - Classification CAN/CSA-W117.2-12: Safety in welding, cutting, and allied processes G40.20-13/G40.21-13: General requirements for rolled or welded structural quality steel/ Structural quality steel W178.1-14
Gas metal arc welding (GMAW), commonly called MIG (for metal/inert-gas), is a semi-automatic or automatic welding process with a continuously fed consumable wire acting as both electrode and filler metal, along with an inert or semi-inert shielding gas flowed around the wire to protect the weld site from contamination.

4043 aluminium alloy [1] [2] [3] is a wrought aluminium alloy with good corrosion resistance typically used as filler material [4] [5] for welding of aluminium parts. It contains high amounts of silicon (between 4.5 and 6%) and trace amounts of other metals. [6] It is grey in appearance and is sold as either welding wire or welding rod for TIG ...
Aluminium alloys are often used due to their high strength-to-weight ratio, corrosion resistance, low cost, high thermal and electrical conductivity.There are a variety of techniques to join aluminium including mechanical fasteners, welding, adhesive bonding, brazing, soldering and friction stir welding (FSW), etc. Various techniques are used based on the cost and strength required for the joint.
The type of current used plays an important role in arc welding. Consumable electrode processes such as shielded metal arc welding and gas metal arc welding generally use direct current, but the electrode can be charged either positively or negatively.
