  The high vacuum diecasting method developed is gradually being used for new products requiring heat treatment or arc welding. In this study, MIG welding was performed on diecastings, and welding quality which influences internal gas volume of diecastings, electrode wire types were examined.<br>  When the gas content of diecastings was 1.6 mL/100 gAl, bead surface was excellent for both A4043 and A5356 . At 3.5 mL/100 gAl, bead surface was excellent for the A4043 electro wire. For A5356, considerable smat was generated and bead line was disturbed at 3.5 mL/100 gAl. In the case of Al-Si diecastings, bonding elongation is considerably lower with A5356 wire than A4043 wire. Reasons for brittle welding areas when A5356 is used are because the concentrated blow hole becomes the starting point of cracks and crack formation changes from inside grain to grain boundary.
