This paper highlights the application of the keyhole gas tungsten arc welding (KGTAW) process for joining titanium pipes used in the extractive metallurgy industry. Experiments have been carried out to establish the advantages of this method of joining over a conventional approach. The assessment of microstructure, mechanical properties and corrosion resistance in a simulated environment was also conducted. The results show that the KGTAW process is a high productivity process which is very suitable for titanium fabrication
