How to weld iron castings? Which welding method is adopted? What kind of electrode? What is the specific operation process? If possible, please give examples.
Welding method and welding of cast iron artifacts is basically the same but with different electrode welding of cast iron have special casting iron electrode
The welding of cast iron parts is made of cast iron special electrode, that is to say, pig iron welding rod. Because the iron chemical and physical properties are special, so the welding conditions of iron castings are higher, first of all to butt welding parts for heating, heating speed is not too fast, slow heating, heating temperature to about 60-70 degrees can be welded (conditional temperature can be higher) the best welding in thermal insulation under the condition of welding method with ordinary welding, the welding is good, after completion of welding to insulation, generally use the workpiece buried in lime powder in thermal insulation.
