The weld access hole or rat hole is a structural engineering technique in which a part of the web of an I-beam or T-beam is cut out at the end or ends of the beam. The hole in the web allows a welder to weld the flange to another part of the structure with a continuous weld the full width on both top and bottom sides of the flange.

The AWS defines welding PQR as a record of welding variables used to produce an acceptable test weldment and the results of tests conducted on the weldment to qualify a Welding Procedure Specification. For steel construction (civil engineering structures) AWS D1.1 is a widely used standard.
For example, AWS B1.11 explains how to visually examine welds; AWS B2.1-1-004 explains welding carbon steel of thickness range of 18 through 10 gauge with semiautomatic metal gas arc welding; and AWS C2.20/C2.20M explains metalized zinc cathodic protection systems. Some codes also describe the standards used by AWS to certify welders ...

In the USA, welder qualification is performed according to AWS D1.1, [1] ASME Section IX [2] and API 1104 [3] standards, which are also used in some other countries. Some States have their own Welder Qualifications that supersede AWS Qualifications, but most defer to AWS, ASME or API.
The researchers analyzed historical data on childhood blood-lead levels, leaded gas use and U.S. population statistics, determining that more than 170 million Americans had "clinically concerning ...
