Welding Cast Iron Gas. These methods include gas welding arcstick welding MIG welding and TIG welding. To do this it is better to know the proportion of the materials which make the iron very hard and strong.
Two types of filler metals are available. Following is a brief explanation of each. Oxy-acetylene welding of cast iron is comparatively easy if attention is paid to some simple rules.
Cast iron can certainly be welded and brazed with TIG brazing included.
However its a metal thats commonly welded and can produce a strong component that will last just as well as a cast product without welds. In MIG welding the electrode wires are usually nickel or Monel but copper alloys may be used. Compared to the Arc-based processes for welding cast iron the heating process is much slower with gas welding. The repairs may be made in the foundry where the castings are produced or may be made to repair casting defects that are discovered after the part is.
