Flux-cored arc welding is known for its high deposition rate because it utilizes a continuously fed tubular electrode that contains a flux. This method allows for the simultaneous feeding of the filler material and the shielding gas, facilitating a more efficient and higher volume of weld metal to be deposited in a shorter period of time. This is particularly advantageous when working on thicker materials or in applications where speed is critical.

Compared to other welding processes, flux-cored arc welding can deposit metal at a rate that surpasses many other methods. For instance, MIG welding also has a reasonably high deposition rate, but it generally does not match that of flux-cored arc welding when considering thicker materials or more demanding applications. TIG welding, while providing high-quality, precise welds, typically has a lower deposition rate due to its procedural nature and the method of manual feeding of the filler rod. Oxy-fuel welding is mainly used for cutting and welding thinner materials and also does not provide the same level of deposition rate as flux-cored arc welding.
