    Feb 03 2017 · I d also do dye penetrant testing on the finished repair to the anvil about 48 hours after all welding and grinding are completed. Some wear-hardening steels and alloy steels can test OK after welding is done but 24-48 hours later post weld cracking can occur. You can get up to 90 percent stress relief by heating the metal to just under the critical temperature but some steels can become brittle after thermal stress relief at these temperatures. That cover the basics of how welding affects heat-treated metals and some of the ways we can counter those effects with heat-treatment techniques.
