'CSA Standard W47.1-09 CWB Welding Supervisor Practice Test 2026 – All-in-One Comprehensive Guide to Exam Success!'

In S-class welder qualification tests, the requirements for fillet welds and undercut are not open-ended. The standard defines fixed maximums for the size of fillet welds and for the allowable undercut, and these limits are specified for each joint geometry used in the test. This means for every geometry in the qualification, there is a specific cap on how large the fillet weld can be and a specific cap on how deep or wide the undercut may be. These fixed limits provide objective, repeatable criteria so a welder’s performance can be consistently evaluated across different tests and welders. If either dimension exceeds its limit, the weld would not meet qualification, regardless of other factors. There isn’t a scenario where only one dimension is fixed; the standard addresses both fillet weld size and undercut for each geometry.
