Abstract

Low alloy steels contain a few per cent (typically between 1 and 7%) of elements such as Cr, Ni, Mo and V. This category includes chromium steels (containing up to 5% Cr and 1% Mo) and nickel steels (containing up to 5% Ni). With increasing carbon or alloy content, low alloy steels generally become more difficult to weld as the heat-affected zone hardness increases. There are many practical aspects to be considered while fabricating equipment involving these materials, especially for the fertilizer, refinery, and petrochemical industries.

This webinar would focus more on the following practical aspects in welding one of the most widely used low alloy steel categories i.e., Cr-Mo steels.

1. Material Procurement
2. Welding Processes
3. Welding consumable selection
4. Welding Procedures
5. Post weld Heat Treatment
6. Execution control
7. Repair welding
8. Dissimilar welding
