Reducing Hard Zones in Dissimilar Metal Welds by Rami Ghorbel is a document available to read on EtoBox.
Controlling welding parameters such as preheat temperature and maximum interpass temperature can reduce or eliminate hard zone formation in dissimilar metal welds. An experimental study found that maintaining an optimum preheat temperature based on base metal thickness, along with a controlled cooling rate, drastically reduced or eliminated hard zones when using ENiCrFe-3 electrodes. However, these hard zones were not eliminated when using E309 stainless steel electrodes. The composition of the welding elec
