Welding Procedure Specification and Welder approval based on
AWS D.1.1: Structural Steel Welding Code
ASME IX: Welding and Brazing Qualifications
API 1104: Welding of Pipelines
The Certified Welding Inspector (CWI) plays an important role during any welded construction activities ensuring the required specifications and standards are followed. Due to the numerous materials and processes associated with metal joining (welding) THIS PRESENTATION SHALL SHOW ONLY THE BASIC WELDING PROCESSES AND EXAMINATION METHODS (NDE). National and International Codes and Specifications along with measuring devices are the Inspector’s tools. Hopefully the following presentation shall give an insight into basic welding inspection.

There are numerous welding processes including arc welding, electron beam welding,
friction welding, laser welding, and resistance welding. This article will concentrate on arc
welding, which is the most common technique used to join most steels. Factors affecting
weld quality will be discussed and how to avoid common weld defects will be presented.
Arc welding requires striking a low-voltage, high-current arc between an electrode and the
base metal. The intense heat generated with this arc melts the base metal and allows the
joining of two components. The characteristic of the metal that is being welded and the joint
type (i.e. groove, fillet, etc.) dictates the welding parameters and the procedure that needs to
be followed to obtain a sound weld joint.
