Question: What type of welding electrode should be used to weld 1Cr20Ni14Si2 and 20G together? Thank you
1Cr20Ni14Si2 welding material can be used first

It is because the thermal conductivity of stainless steel is 1/4 to 1/2 that of carbon steel, and its expansion coefficient is approximately twice that of carbon steel; there is concern that uneven deformation between the two may cause the 20G material to tear
Yes, following the principle of choosing the higher option, select electrodes or wires made of 1Cr20Ni14Si2 welding material.
