Weldability of Annealed, Normalized, Quenched and Tempered Steels

We frequently receive requests for help developing welding procedures for welding on quenched and/or quenched and tempered steels.  Sometimes the call for help is to determine why these steels cracked after welding and how to prevent it from happening in the future. Understanding the supplied condition of the steel you are going to be welding […]

Factors Affecting Cooling Rates of Welds and Heat Affected Zones

Different ways to manage the rate of cooling

Our next article will discuss a question we are asked quite often: Can we eliminate preheating before welding?   Preheating is necessary to slow the cooling rate down after welding which in turn avoids excessive hardening of the weld and heat affected zone.  Eliminating preheat can lead to hydrogen induced cracking and catastrophic failure.  A […]
