| Abstract: | The welding technology and microstructure in welded joint zone of the alloy are studied by means of metallographic microscope, scanning electron microscope, electron microprobe analyzer and X-ray diffractometer. Experimental results indictae: high quality weld joint can be obtained by using Al-Si alloy welding wire (HS311) and lower welding current. The welding process may be widely applied to various aluminium alloy castings. |
