DESCRIPTION
Welding defects are the result of poor control of the essen al and non-essen al welding main variables described in the welding procedure specifica on. However, are all welding defects unacceptable by the chosen standards of construc on? Yes, within certain limits.
OBJECTIVES
This course offers inspectors, welders, engineers, and professionals working in the welding field an explana on why some welding defects can be accepted and at the same me reduce the costs of non-quality weld seams. This course will focus on the differences between each of the different construc on standard philosophies ( me distributed equally among the standards is described below) and clarify why the same defect is at mes accepted and/or rejected.
Upon comple on of this course, the par cipants will be able to:
Iden fy causes of weld defects
Understand the welding defect tolerances of each standard
Understand why tolerances vary for the same welding defect depending on the type of equipment, its posi on, orienta on, etc.
TARGET ATTENDEES
Engineers
Inspectors
Welders
Technicians
Contractors
Professionals working in the field
