摘要：
The effect of preheat temperature on the microstructure obtained in the heat-affected zone (HAZ) and the carbide zone in the weld metal adjacent to HAZ has been studied in multipass welds for the as-cast and ferritic ductile cast irons. The welding was carried out with manual shielded metal are welding using ENiFe-CI filler metal. Ultrasonic, microhardness distribution, tensile and impact tests were conducted to evaluate the quality of welded joints. (C) 1999 Elsevier Science B.V. All rights reserved.
