This equipment utilizes a continuously fed wire electrode, automatically controlled by the user, to create the weld. The operator retains control over travel speed and positioning, while the device manages the wire feed rate. A common example is the Gas Metal Arc Welding (GMAW) system, also known as MIG (Metal Inert Gas) welding.
This type of welding offers a balance between control and automation, resulting in higher productivity than fully manual methods while retaining adaptability to varying joint configurations and material thicknesses. Its development significantly increased the efficiency of many industrial welding processes, particularly in manufacturing and construction, contributing to faster production times and reduced labor costs. Its adaptability allows for its use in various sectors, including automotive, shipbuilding, and pipeline construction.
