Feature modeler of welded structure provides both 3D-geographical and non-geographical features for the off-line programming of arc welded robot. Welded structure is regarded as an assembly, the design of welded stru...
In this paper, technology margin experiment of hollow cathode fusion arc welding (FAW) and penetrating arc welding (PAW) is presented in detail. The advantages of PAW. compared with FAW, are better weld formation, nar...
By using the nickel welding wire, the effect of alloying elements on the chilling tendency of partial fusions zone (PFZ) of arc-welded ferritic ductile iron and the mechanical properties of weld metal have been system...
The effect of Ca,Ba,Bi and Al on the amount of carbide in ductile iron weld metal,the microstructural characteristics of ADI weld metal and the effect of heat treatment process on the microstructure and mechanical pro...
