Abstract

An important metallurgical difficulty in arc welding of high-strength aluminum alloys isformation of solidification cracking. In this work, an attempt is made to reduce thesolidification cracking in welding of aluminum alloys through vibratory treatment. Thematerial used for the investigation is AA2014 aluminum alloy, which is highly prone tosolidification cracking. Vibratory treatment was carried out in the frequency range of 100Hz to 3700 Hz. Weldments made with and without vibratory treatment were compared usingweld cracking tests and other characterization tests such as microstructural analysis. Thetest results show that by applying vibratory treatment, solidification cracking can belargely controlled in arc welding.
