Murex Welding Products has published a free Guide to MIG Welding that includes a wealth of useful information, as well as details about the company's extensive range of MIG welding machines and accessories.
MIG is the most widely used of the arc welding processes, being suitable for everything from hobbies and small fabrications or repairs, through to large structures, shipbuilding and robotic welding. MIG can be used on a broad range of materials and thicknesses, and the latest SuperPulse technology enables MIG to give a finish that is similar to that obtained with TIG welding, but with the much faster speeds.
The guide discusses the principles of the process and gives practical advice on how to carry out MIG welding tasks. Ease of use is a major benefit of MIG in many applications, but speed is also an advantage due to MIG being far quicker in laying down weld metal than TIG, MMA or gas welding.
Typical applications for MIG are discussed in the guide. These include automotive subassemblies and bodywork, ranging from conventional MIG for most bodywork, to heavy-duty MIG for lorry chassis and off-highway vehicles, as well as lower-current MIG brazing of thin-gauge, high-strength steels. MIG is also used extensively in automotive and general repair workshops.
Non-automotive applications include the assembly of white goods and office furniture, the joining of structural steelwork for the construction industry, as well as repair work in ship repair yards, and welding tasks in the process industry for pipework and the fabrication of vessels.
Murex has been involved with MIG welding since its early commercialisation and the company describes itself as a technology leader, launching new MIG welding sets with functions and features that set them apart from the competition. The latest development is SuperPulse MIG welding, which gives the advantages of pulse welding combined with the finish that is normally associated with TIG welding. With the level of control available in SuperPulse machines, the operative can effectively manage the welding parameters to 'mix and match' the modes of transfer to suit the material and the required combination of speed and quality.
Another application for which MIG is increasing in popularity is brazing. This enables good strength to be achieved when joining thin materials - even down to 0.5mm.
