How is turbo turbine wheel casted?
One of the steps is welding turbine wheel wax pattern into wax gating system manually. The welding process can be explained like this: Using liquid wax(heated) as “welding material” to form a join between turbine wheel wax pattern and wax gating system as the liquid wax cools.
