| Abstract | ||
| Theinfluence ofshot peening onbending strength using MIG welding joint aluminum alloys 2024-T351 was studied. The paper implements many series of experimental techniques to figure the bendingstrength of all specimens , by performance hardness, shot peen, remaining stress and bending examinations for un-joint and joinedsamples. (MIG) process has implemented onsheets of "8mm thickness" to getbutt joiningconnections with measurement of (200 *100* 8) mm with joining readying angle in formsingle and double V of 75⁰and flatjoinby "ER- 4043(Al-Si5)"as a "groutmetal"and "argon" as protected gas. The juncturesareexamined by"X-ray radiography"and exceptedtheimperfect joint, then Welding joint exposed to heat treatment to removed joiningresidual stress. Hardness was measured using Vickers test and the specimens microstructure were examined, finally bending testimplemented on the samples which fabricated into typicalexaminationsample dimensionagreeing to the ASTM (E 190-92) of welded and un welded joints, and then ejaculation by steel ball in diameter 1.25 mm for 10 min to show the influence of shot peening on weld bending The Results of bendingqualities for MIGweld connected showdecay when comparing it with theunwedded joints and chiefly along the HAZ .but unweddedsamples were fiascoes nigh the middle line of the sample shot peening contributed in improvement of bending process for all specimens. Ansysprogram was used to conduct stress analysis operations. | ||
