Welding is a metallurgical operation, and to obtain the good clean weld metal possessing the desirable physical and chemical properties, the suitable control is required. If welding rods of superior quality are used, welding technique is the most important factor that imfluences on properties of deposited metal. The author believes that welding technique should be performed with considering the transmission of welding heat at the joint. This paper deals with the following items.; 1. General consideration on deposited metal 2. Impact fracture of deposited metal and its change 3. Effects of heat treatment on the grain growth of deposited metal 4. Effects of short-time local heating on microstructure, hardness and impact resistance of deposited metal 5. Some considerations on the shape of deposited metal and welding process Moreover, this paper describes on effects of silicon and manganese, results of thermal analysis and some of microstructures of deposited metal heat treated.
