American Welding Society Forum
hello My name Is Mac Heinrich I am a Welding and Manufacturing student at Mitchell Technical Institute and we have Just finished D1.1 2015 and now we are on ASME Clause 5 out of the API Standard 1104 Twenty-first Edition. My question is that what are the Preheat and post weld heat treatment (PWHT) temperatures in section 220.127.116.11 Its gives you a description but not the minimum and maximum temps. Thank you for taking the time to answer my question
I am somewhat confused since you refer to both ASME and API in the same sentence.
API 1104 doesn't addressed many of the issues included in AWS structural codes because API doesn't recognize the concept of prequalification. Thus, one must qualify the process, including the techniques, proposed for production to demonstrate the proposed WPS will produce the required mechanical properties.
