This document provides hints for welding steel with a high carbon content. It stresses the importance of understanding the material being welded by checking the mill certificate for its carbon equivalent value and chemical composition. A high carbon equivalent value indicates the steel will be more difficult to weld. It advises welding technicians to involve engineering resources when working with steels of unknown composition to help determine weldability.

The values for the chemical elements contained in
The steel you’re about to weld will be found in the
mill certificate supplied with the steel.
Plug those values into the formula below to
determine the CE (Carbon Equivalent) of the steel.
(Always include your Engineering resource in these situations)
