The effects of single-pass/double-pass technique on friction stir welding of aluminium
Friction stir welding is a solid state welding that use the idea of frictional heat to soften stirred materials without the need of melting. This study is focusing in the effects of single-pass/ double-pass technique on friction stir welding of aluminium. Two pieces aluminium alloy (AA1100) with the...

Friction stir welding is a solid state welding that use the idea of frictional heat to soften stirred materials without the need of melting. This study is focusing in the effects of single-pass/ double-pass technique on friction stir welding of aluminium.

Three different rotational speeds of 1400 rpm, 1600 rpm and 1800 rpm respectively were used for both groups of single-pass and double-pass.

Welded specimens using double-pass technique shows increasing value of tensile strength and hardness value. Therefore, the optimum parameters in FSW process were double-pass technique with rotational speed of 1800 rpm. |
