Cracking in Ferritic Steels

Webinars 19 October 2022

Welding and Joining Technical Group: Back-to-Basics Webinar: Cracking in Ferritic Steels

This second back-to-basics webinar will be looking at the three most important cracking mechanisms that may occur in C/Mn and low alloy steels:

  • hydrogen induced cold cracking
  • solidification cracking
  • lamellar tearing

The cause(s) of these cracking problems will be explained drawing on some of the metallurgical principles that were discussed in first back-to-basics: An Introduction to Steel Metallurgy*.

Importantly, the measures that can be taken to avoid or mitigate the cracking will also be covered.

Who should attend?

  • those with little or no knowledge of welding technology
  • those just entering the welding industry
  • those wanting to gain an appreciation of the subject
