Can You Weld Mild Steel to Cast Steel?

1 challenge to retained is the potential for cracking in the heat-affected zone (haz) of the weld joint, especially if proper preheating and post-weld temperature treatment method (pwht) aren't performed. Cast steel can be prone to cracking due to its higher carbon content and inner stresses, so it's significant to follow advised processes and welding parameters to minimize the risk of defects.
