Can be carried out satisfactorily as per machine manufacturers recommendations for suitable tool type - feeds and speeds. 4 Place weld starts and stops preferably at least 50-100 mm 2-4 from a corner in order to avoid excessive stresses in these regions see Figure 1. If the weld and heat affected zone cool too quickly we are in trouble.
Usually for T1 steels less than 1 in.
AISI 8620 Steel is a low alloy nickel chromium molybdenum case hardening steel. When welding a quench and tempered steel like T1 which has received a heat treatment to achieve a particular strength level use much lower preheat and interpass temperatures to help control heat input so the designed strength level is maintained. Preheat is required and PWHT is. Thanks Sean By GRoberts Date 04-16-2002 1524 What heat treat state is your base metal in.
