The use of concentrated heat stream to repair AlZn10Si8Mg alloy castings
Original language description
The present paper discusses the possibility to use three different sources of concentrated heat stream to repair superficial defects on AlZn10Si8Mg alloy castings. Simulated defects were prepared on specimens taken from a production casting made with the use of low-pressure casting method. The energy sources used to repair the defect were those known as MIG/MAG, TIG, and ML (micro-laser) methods. As the filler, a AlSi5 welding wire was used. The quality of repair was assessed based on both destructive and non-destructive testing. To evaluate porosity of the performed overlay welds, the computer X-ray tomography technique was employed. Metallographic examination was used to assess macro-and micro-structure of overlay welds, measure geometrical parameters of the welds and the heat-affected zone, and determine values of SDAS microstructure parameter. Hardness of overlay welds and the casting material was measured with the use of Brinell hardness machine.
