Carbon Equivalent (CE) is a key factor that decides how easily steel can be welded. In this short video, you’ll understand what CE means, how it is calculated, and why higher CE increases cracking risk. Learn how alloying elements like carbon, manganese, chromium, nickel, and molybdenum affect weldability. We also explain CE ranges, when preheating is required, and how proper cooling control improves weld quality. This knowledge helps welders, inspectors, and engineers avoid weld defects and mak
