Some Studies on Temperature Distribution Modeling of Laser Butt Welding of AISI 304 Stainless Steel Sheets
In this research work, investigations are carried out on Continuous Wave (CW) Nd:YAG laser welding system after preliminary experimentation to understand the influencing parameters associated with laser welding of AISI 304. The experimental procedure involves a series of laser welding trials on AISI 304 stainless steel sheets with various combinations of process parameters like beam power, beam...
متن کاملMicrostructural analysis of expanded stainless steel 304 cylinders
A gas-gun technique to radially expand cylinders of a chosen material, based on a technique developed in 1979, has recently been re-established. Stainless steel 304 cylinders of length 160 mm, internal diameter 67 mm and thickness either 0.5 or 1.5 mm have been expanded using a 70 mm bore single-stage gas-gun. Microstructural analysis of the recovered specimens was performed using optical micro...
متن کاملFinite Element Simulation of Nd:YAG laser lap welding of AISI 304 Stainless steel sheets
Laser beam welding (LBW) is one of the most important manufacturing processes used for joining of materials. It is also a remarkably complicated, nonlinear operation involving extremely high temperatures. Since its invention more than two decades ago, laser beam welding has been more of an art than a science. Laser welding of austenitic stainless steel AISI 304 the candidate material of this re...
متن کاملCompressibility of 304 Stainless Steel Powder Metallurgy Materials Reinforced with 304 Short Stainless Steel Fibers
Powder metallurgy (P/M) technique is usually used for manufacturing porous metal materials. However, some P/M materials are limitedly used in engineering for their performance deficiency. A novel 304 stainless steel P/M material was produced by a solid-state sintering of 304 stainless steel powders and 304 short stainless steel fibers, which were alternately laid in layers according to mass rat...
متن کاملDesign optimization of cutting parameters for turning of AISI 304 austenitic stainless steel using Taguchi method
In the present work Taguchi method is used to optimize cutting parameters during dry turning of AISI 304 austenitic stainless steel with AlTiCrN coated tool. The coating was deposited on fine-grained K-grade (ISO K-20) cemented carbide cutting insert using physical vapor deposition (PVD) technique. The turning parameters evaluated are cutting speed of 200 and 260 m/min, feed rate of 0.20 and 0....
