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
