Aluminium　alloy　6082-T6　is　known　for　its　high　strength　and　cost　effectiveness,　making　it　a　popular　choice　for　thin　sheet　structures　such　as　automotive　body　panels.　However,　the　welding-induced　softening　of　the　heat　affected　zone　(HAZ)　and　the　insufficient　strength　of　the　filler　metal　are　the　primary　factors　limiting　its　broader　application.　In　this　study,　the　lower　heat　input　cold　metal　transfer　welding　method　is　employed,　utilizing　heat-　treatable　reinforced　AlSi10Cu2Mg0.7Zn1　wire　to　weld　6082-T6　plates.　Additionally,　the　impact　of　the　baking　paint　process　within　the　automotive　manufacturing　workflow　on　the　evolution　of　microstructural　characteristics　of　the　HAZ　and　Weld　Zone　(WZ),　as　well　as　the　mechanical　properties　of　the　joints,　is　investigated　in　detail.　The　findings　indicate　that　the　AlSi10Cu2Mg0.7Zn1　filled　WZ　contains　a　small　quantity　of　theta,　Q,　and　beta　phases,　alongside　a　significant　amount　of　reticulated　eutectic　Si　distributed　among　the　Al　dendrites.　Notably,　the　strength　of　the　WZ　is　enhanced　compared　to　that　of　conventional　Al-Si　and　Al-Mg　wires.　During　the　baking　process,　the　WZ　exhibits　the　precipitation　of　a　small　amount　of　fine　beta＂　and　beta　＇　＇　precipitates,　which　elevates　the　tensile　strength　of　the　WZ　to　272　MPa　and　the　yield　strength　to　179　MPa.　Furthermore,　the　baking　treatment　promotes　the　further　growth　of　beta　＇　＇　in　the　HAZ　of　the　joints,　while　fine　beta＂　phases　are　reprecipitated　within　the　Al　matrix.　The　combined　influence　of　these　two　precipitated　phases　results　in　an　increase　in　the　tensile　strength　of　the　HAZ　by　29　MPa.
