The qualification of welding procedures is necessary to ensure that the selected welding parameters can produce sound welds. Qualification typically involves a combination of destructive and nondestructive testing. When a particular code, such as AWS D1.1 or ASME Section IX is used, the code will dictate the type and numbers of tests necessary in order […]
When qualifying a welding procedure specification (WPS) for fillet welds per Clause 4 of AWS D1.1 Structural Welding Code you must only perform a single test. You must do macroetches in three locations as shown below. It is assumed that if we can show root fusion at these three locations that our welding procedure is […]
The purpose of welder performance qualifications is to ensure that the welder can deposit sound welds. There are several tests, both destructive and nondestructive, that are used to evaluate a welder’s ability to deposit good welds. Below are four of the most common test applied for these qualifications: Visual Inspection (VT) Visual inspection is […]
