Chapter 24, Problem 1R
Why is it important to select the correct welding code or standard?
Expert Solution & Answer
To determine
The reason for selecting the correct welding code or standard.
Answer to Problem 1R
The reason for selecting the correct welding code or standard is to judge the quality of weld.
Explanation of Solution
A welding code or standard is a list of rules and principles that may that may be applied to certain products or items. A welding code specifies certain specifications and requirements for a particular type of weld.
These are the detailed outlines established by various agencies and organizations that explains how to lay out a particular weld, how it should be performed and tested. These detailed outlines are known as codes, standards and specifications.
Codes, standards and specifications are a list of principles, rules and regulations that are needed to ensure that skilled welders across the world can produce the same type of weld with the same level of strength, safety and reliability.
Products which are fabricated as per a welding code or standard are usually inspected and checked in order to ensure the concurrence
There are some commonly used codes for welding. These are as follows.
- API standard 1104
- ASME Section IX
- AWS D1.1
- AWS SENSE
Selection of a code or standard is done by the designers or the engineers.
A correct welding code or standard is very necessary in order to judge a weld and compare the quality of the produced welded workpiece with that of ideal sample.
Conclusion:
The reason for selecting the correct welding code or standard is to judge the quality of weld.
