Welding Inspection and Certification

This area emphasizes the importance of professionals who inspect welds and it provides an overview of what organizations have standards for inspection performance.

Safe Practices for Welding Personnel

The potential for injury from radiation, burns, vapors, and explosions is substantial when welders perform their jobs improperly or when their work area is not maintained in an orderly, safe, clean and prudent manner. In addition, a myriad of agencies exert control over worker safety. This area covers the equipment, procedures, situations, and documentation needed to comply with mandated safety requirements and prevent accidents on the job.

Metal Joining and Cutting Processes

This area introduces a number of welding and cutting processes (including arc welding, brazing, resistance welding, soldering, and solid state welding), the advantages and limitations of each, and tips for troubleshooting. It also addresses how to choose the right process for the right application. The AWS filler materials system, process techniques, problems, and solutions are also explained.

Weld Joint Geometry and Welding Symbols

The universality of AWS weld symbols ensures continuity of communication between designers, supervisors, inspectors, welders, and regulatory bodies. Most Gov’t Departments of Defense and Transportation and Suppliers, Fabricators - use the AWS welding symbols systems. This area reveals the relationship between these symbols and the actual appearance of welds and their component parts, the configuration of welds, and weld joint geometry.

Documents Governing Welding Inspection and Qualification

The preparation of a Welding Procedure Specification is the true nucleus of a successful welding operation. This area examines the core of welding control with introduction to drawings, standards, codes and specifications, control of materials, alloy identification, and the qualification of procedures and welders.

Metal Properties and Destructive Testing

Mechanical properties of metals include strength, ductility, hardness, toughness, and fatigue strength. Chemical properties of metals have a direct effect on corrosion-resistance and weld ability. This area explains how destructive testing is used to ascertain the actual mechanical and chemical values of metals and why this information is crucial for design engineers.

Welding Metallurgy for Welding Personnel

Mechanical properties of metals are all affected by the metallurgical transformations that result from the elevated temperatures of welding. Welding professionals need to know how metals will behave once welded in order to better understand which materials will be safe, economical, and high performing in different conditions. This area is a must for anyone who needs to understand the welding and fabrication process at the most basic level. It is particularly valuable for those who are responsible for the specification of base or weld metal alloys and their pre- and post- weld treatments.

Weld and Base Metal Discontinuities

Rework and repair are estimated to be 10-15% of actual fabrication costs.  That’s $7 billion annually in the United States alone. So, when is a defect acceptable and a discontinuity unacceptable? This area describes different types of discontinuities (including cracks, incomplete fusion, incomplete joint penetration, inclusion, porosity, undercut, overlap, convexity, spatter, lamination, lamellar tears) and explains why these problems occur, how to identify them, and how can they be avoided.

 Visual Inspection and other NDE Methods and Symbols

Visual inspection is the first line of defense against expensive rework and repair and it is the most economic quality control step any welding operation can employ. This area covers visual inspection tools and their proper deployment, as well as an overview of other NDE methods including penetrant testing, magnetic particle testing, radiographic testing, and ultrasonic testing.
