Development of Al-Ti-N Composite Coatings on Commercially Pure Ti Surface by Tungsten Inert Gas Process
The present work aims to modify surface properties of pure Ti by development of Ti-Al-N intermetallic composite coatings. In this regard, tungsten inert gas (TIG) cladding process was carried out using Al 1100 as filler rod with Ar and Ar+N2 as shielding gases. Phase and structure of the samples were investigated by X-ray diffraction (XRD) technique, optical microscopy (OM) and scanning electro...
متن کاملThe principle Of Tungsten Inert Gas (TIG) Welding Process
Process This chapter presents the principle of tungsten inert gas (TIG) welding process besides important components of TIG welding system and their role. This process is also known as gas tungsten arc welding (GTAW) process. Further, fundamentals of heat generation, arc stability and arc efficiency have also been described. Additionally, comparison of argon and helium as shielded gases has bee...
متن کاملWelding of 304L Stainless Steel with Activated Tungsten Inert Gas Process (A-TIG)
Gas tungsten arc welding is a popular process in those applications requiring a high degree of quality and accuracy. However, this process has a big disadvantage against the substantially high productivity welding procedures. Hence, many efforts have been made to improve its productivity. One of these efforts is the use of activating flux (A-TIG welding). In this study, the performance of A-TIG...
متن کاملStructure-property Interaction in Flux Assisted Tungsten Inert Gas Welding of Austenitic Stainless Steel
Austenitic stainless steel SS304 grade was welded with active Tungsten Inert Gas (TIG) welding process by applying a flux paste made of SiO2 powder and acetone. SiO2 flux application improves the weld bead depth with a simultaneous reduction in weld bead width. The improvement in penetration results from arc constriction and reversal of Marangoni convection. Experimental studies revealed that t...
متن کاملCharacterization of Tungsten Inert Gas (TIG) Welding Fume Generated by Apprentice Welders
Tungsten inert gas welding (TIG) represents one of the most widely used metal joining processes in industry. Its propensity to generate a greater portion of welding fume particles at the nanoscale poses a potential occupational health hazard for workers. However, current literature lacks comprehensive characterization of TIG welding fume particles. Even less is known about welding fumes generat...
