Quality and productivity play important role in manufacturing market. The main objective of industries is to produce better quality product at minimum cost and increase productivity. Welding is the most vital and common operation use for joining of two similar and dissimilar parts. In this paper an overview of current research in Keyhole Tungsten Inert Gas (K-TIG) welding of different material has been presented. K-TIG is a high speed, single pass, full penetration welding technology that eliminates the need for wire, edge bevelling or skilled operators and produces flawless welds faster than TIG welding in materials up to 13mm in thickness. Fundamental concepts and definitions commonly used in keyhole Tig welding are introduced. The purpose of this review is to introduce the possibilities for further research in this field.
