Temper Bead Welding-– ASME Section IX
Temper Bead Welding (TBW) Temper Bead Welding (TBW) was adopted into the 2004 Edition of the ASME Boiler and Pressure Vessel Code, Section IX; the adoption of TBW has permitted welders to strategically exploit the effects of welding. Of particular note, is the ability to utilize TBW to create a weldment with improved strength and low temperature impact properties without the application of post weld heat treatment (PWHT). However, to reliably obtain these benefits requires development of a robust welding procedure, performance qualification and parameter controls during production welding. The origins of the process can be traced back to the half-bead repair approach using SMAW electrodes
