FRICTION STIR WELDING OF AA6063- EXPERIMENTATION AND TESTING
Keywords:
Friction Stir welding,, Temperature, Tool Material, Tool geometry.Abstract
Generally, for joining process for soft materials such as aluminum alloys and also for hard materials like steels friction stir welding is usedas it avoids many of the common problems obtained in fusion welding. Also if we gone through joining of aluminum alloys could be usually faced problems in many cases available in various fields like automotive, aerospace, ship building industries, electronics etc. where fusion welding is not possible due to large difference in physical and chemical properties of the components to be joined. Mainly the problems occurred in the welding processes like porosity formation, solidification cracking, and chemical reaction may arise during fusion welding of dissimilar materials. Even if good welded joints may be obtained in some limited cases with special attentions to the joint design and preparation, process parameters and filler metals.
