“…This will reduce the strength especially the sample made with 100µ interlayer makes a bulk deposition of (Zn) over TMAZ as explained by Tailer 8 and Caroline Jonckheere 14 . This leads poor strength due to lack of fusion between the parent metal and pores formation.…”

The use of lightweight materials in the production of cryogenic tanks, spacecraft body etc. are becoming the need to develop dissimilar metal FSW joints. Friction stir welding (FSW) is a novel and inspired light metal joining process since it is not involved with the melting of the parent metal. In this work, two Aluminium 7020 plates were welded with Zn as an interlayer, using friction stir welding method. Different joints were made by varying the thickness of interlayer (Zn) and thereafter the characterization is done against mechanical properties and microstructure of weld nugget. The test result shows that the specimen joint with 10µ Zn interlayer has higher mechanical properties than samples made with 5µ, 10µ, 20µ, 40µ and 100µ Zn interlayer. To analyze the cause, further optical studies (Image analyzer and SEM analysis) were carried out and found the interlayer dispersion plays a vital role in weld strength. As a conclusion addition of Zinc interlayer with preferable thickness (10µ) in Al7020 FSW joints improve tensile strength and hardness than the FSW joints made with higher and lower interlayer thickness.

“…This pin is an extension of a shoulder of a 20 mm Ø with a spiral grooves on the shoulder surface (see Fig. 1 of Jonckheere et al [30] for a full scheme of the tool geometry). The tool was inclined backwards by 1°so as to facilitate the easy passage of the material into the tool shoulder without tearing of the 0.2 mm thick cover sheet ahead of the tool.…”
