EC
Welding inspection includes which of the following? - Answer Visual and nondestructive
examination of the welds, Review of specifications, welding procedures, and welder
qualifications, Review of joint designs and cleaning procedures.
Which of the following tasks are not normally performed by the inspector prior to
ES
welding? - Answer Check the appearance and size of welds.
. Who is responsible for the "quality craftsmanship" of weldments? - Answer The welder.
During welding operations, the inspector should: - Answer Confirm welding parameters
and techniques are supported by the WPS and WPQ, Complete physical checks, visual
examinations, and in process NDE, Establish a quality control and quality assurance
umbrella with the welding organization.
Following the completion of welding, and before the completed welds are placed in
service, the inspector should: - Answer a. Verify post weld acceptance and that NDE was
performed at the selected locations, Verify that post weld heat treatments and pressure
testing were performed, if required, and that the results were acceptable, Audit the
, inspection files to identify inaccuracies and incomplete information
If at any time during welding inspection the inspector discover defects or
nonconformances, he/she should: - Answer The defects or nonconformances should be
brought to the attention of those responsible or corrected before the work proceeds
further.
