GENERAL DESCRIPTION OF SUBJECT MATTER FOR EACH LECTURE/DISCUSSION

Topic

General Description of Subject Matter

Inspecting and testing welds

Differentiate between destructive testing and nondestructive examinations methods, describe various non destructive examinations methods and what flaws or defects they identify. Identify and specify various non destructive examination methods using the correct AWS abbreviation. Make a visual inspection of a weld, perform a properly conducted dye penetrant test on a weld, make a safe and proper bend test on a groove weld, describe and identify various laboratory and shop type equipment used to make destructive test on welds. Visually inspect and perform a peel test on a spot weld.

 

 

 

 

Procedure and welder qualifications

List several governmental agencies that use and produce various types of welding codes, understand and relate the reasons for welding codes and specifications. List the essential and nonessential welding variables, define : welding procedure specification” “ welding procedure qualification record””welding performance qualification”.

List the weld qualifications test positions, describe what test specimens are cut from a weld sample and describe the types of test made on each specimen.

 

 

 

ATTENDANCE POLICY

 

 

 

Regular and punctual attendance is expected of all students in all classes for which they have registered. Students absent (excused or unexcused) for 4 classes or more may receive an “F” for the course or may be dropped from the course. A student who is late for a class or leaves early from the class twice will be counted for one absence.  Class participation assignments and exams will be used to determine regular attendance for online students. A student that is compelled to be absent when a test is given, will petition the instructor, in advance, for permission to take the exam early. A student will be allowed to drop one exam from the required exams given during the course. Required work not completed by due dates will not be allow to be turned in without instructor approval.
