**3.3 Welding processes**

The welding processes considered with foremost importance for WAAM depending upon the feasibility and cost benefits may be among Gas Metal Arc Welding (GMAW) process, Gas Tungsten Arc Welding (GTAW) process, and Plasma Arc Welding (PAW) process. Few more welding processes have been also available as discussed in Section 2, but the suitability for WAAM is very high for the above said frequently used welding processes. The selection of a suitable welding process depending on the component to be fabricated is already discussed in Sections 1.2.1 and 1.2.2 above.
