When planning the economics of any welding project, the primary objective is to maximize the desired weld quality and ease of controlling the weld while maintain costs at a minimum. To achieve these goals several factors must be considered.
The choice of gas tungsten arc welding as the preferred process for a given project is based on a combination of the service requirements of the weldments and the cost of GTAW compared to the cost of other processes. While weld quality and the properties required for the intended service of the weldment are often the driving factors in the selection of the process, other factors that impact the cost of welding are the skill levels required, accessibility to the weld, the level of control required, the equipment and consumables needed, and production rates.
Manual gas tungsten arc welding usually requires higher skill levels than other manual processes. Mechanized GTAW requires less operator skill and provides greater control over the process, but equipment costs are higher, and the benefits must be justified by production and quality requirements.
The cost of such items as shielding gases, gas nozzles and lenses or collets, the tungsten electrodes, and filler metals (if used) should be compared with the cost of materials typical of other processes. Filler metal for any application is a compromise involving metallurgical compatibility, suitability for the intended service, and cost. The ability of GTAW to produce certain welds without filler material results in decreased costs compared to other arc process.
