Welding and Metal Fabrication is designed to help you develop all of the skills to become a highly paid versatile welder. In addition, it is designed to make the process of learning to weld interesting and rewarding by having everything you weld on become something you can take home and use. The projects within each of the fabrication and welding chapters are designed to be functional even though the welds may be your first attempts at welding. So at first do not be overly critical of your welding skills, they will improve as you advance through the textbook. In that way, both your fabrication skills and your welding skills will improve together. In the welding field, the ability to lay out, cut out, and assemble a welded part can be as important as good welding skills. This textbook is designed to give you all of the skills needed to be successful in welding.

Gas metal arc welding GMAW , sometimes referred to by its subtypes metal inert gas MIG welding or metal active gas MAG welding , is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal s , which heats the workpiece metal s , causing them to melt and join. Along with the wire electrode, a shielding gas feeds through the welding gun, which shields the process from contaminants in the air. The process can be semi-automatic or automatic. A constant voltage , direct current power source is most commonly used with GMAW, but constant current systems, as well as alternating current , can be used. There are four primary methods of metal transfer in GMAW, called globular, short-circuiting, spray, and pulsed-spray, each of which has distinct properties and corresponding advantages and limitations. Originally developed in the s for welding aluminium and other non-ferrous materials, GMAW was soon applied to steels because it provided faster welding time compared to other welding processes.
