Welding Carbon Steel To Cast Iron. On the flip side prepost-heating the entire workpieces results in more balanced welds. When TIG welding with cast iron a nickel wire is the only real option available for this job.
The high carbon content can make welding with cast iron difficult. By the way we watch your videos in weld class. A few facts about cast iron help in understanding the welding challenges.
One way to handle this is by controlling the cool-down of the cast iron.
You can weld 1018 low-carbon steel to cast iron using shielded metal arc welding SMAW and a nickel-based ENiFe electrode. The high carbon content can make welding with cast iron difficult. However there are a few things you want to remember when welding cast iron to steel. Their structure consists of branched and interconnected graphite flakes in a matrix which is pearlite ferrite or a mixture of the two Fig2a.
