Welding Cast Iron To Steel Tig. The high carbon content causes the carbon to form flakes of graphite. If a job requires cast iron to be welded to mild steel stick welding is a great method to do so.
Pieces of cast iron can be jointly welded by TIG. Clean the casting carefully. Working at 95 Amps on DCEP Direct Current Electrode Positive will.
Normally it has a carbon content of 2 to 4 hardly ten times as much as many steels.
There are occaissions where a weld on the steel part will capture a cast iron part and while they may look welded they usually crack apart after awhile. If it is indeed cast steel then any plain old er70 type mig wire will work. Working at 95 Amps on DCEP Direct Current Electrode Positive will. The heat of a TIG torch is far too focused and localised.
