Abstract:
The paper deals with the physical, chemical properties along with important aluminum applications. Various defects are generated while welding of aluminum alloys one of the severe defects is cracks. Solidification and liquation cracks are generated at various zones of metals. Different mechanical and metallurgical factors affecting the solidification cracking. A variety of weldability tests like Varestraint test, Transvarestraint test, The Cast Pin Tear testHot Ductility test, Strain-To-Fracture test, Reheat Cracking test, Houldcroft (Fishbone) test appliesto investigate the susceptibility of cracking.
