Friction Stir Welding On Aluminum Alloy 6063 Pipe, Azman Ismail, Mokhtar Awang, Hasan Fawad, Kamal Ahmad
Azman Ismail
For Friction Stir Welding (FSW) process, a substantial amount of research done on aluminium plate but very few are found for aluminium pipe due to its tubular shape. A specially customised Orbital Clamping Unit (OCU) was used and fixed on the Bridgeport 2216 CNC milling machine in order to run the FSW on aluminium alloy 6063 pipe butt joint at several welding parameters. This OCU will hold these pipes together tightly, rotate these pipes at the required constant low speed, and ensure easy removal of pipe after the welding process before proceeding for further testing. This paper will study the …

This article provides an analysis of processes for separation CO2 by using carbonic anhydrase enzyme with particular emphasis on reactive-membrane solutions. Three available processes are characterised. Main challenges and prospects are given. It is found that in view of numerous challenges practical applications of these processes will be difficult in near future. Further research is therefore needed for improving existing processes through finding methods for eliminating their main drawbacks such as short lifetime of carbonic anhydrase or low resistance of reactive membrane systems to impurities contained in flue gases from power plants.
