Answers - A weld made without filler metal.
In welding, a discontinuity is defined as: - Answers - An interuption of the typical
structure of a material.
The heat affected zone of a weld is best described by which of the following? - Answers
- That portion of the base metal whose mechanical properties or microstructure have
been altered by the heat of welding or thermal cutting
Welding inspection includes which of the following? - Answers - 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
welding? - Answers - Check the appearance and size of welds.
. Who is responsible for the "quality craftsmanship" of weldments? - Answers - The
welder.
During welding operations, the inspector should: - Answers - 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: - Answers - 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: - Answers - The defects or nonconformances
should be brought to the attention of those responsible or corrected before the work
proceeds further.
, If ASME Section V, Article 1 is specified by the referenceing code, NDE personnel: -
Answers - Shall be qualified in accordance with ASNT SNT-TC-1A or ANSI/ASNT CP-
189.
