Abstract

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