CAREER PROFILE

What is a Welding Inspector?

Welding Inspectors employ their extensive knowledge of welding processes, test methods, discontinuities, materials, qualifications, and standards to ensure that weldments and welding related activities comply with all applicable quality and safety criteria. The role of the welding inspector is critical to the safety and structural soundness of the vast number of buildings, vehicles, machinery and consumer products that require strong, secure welds.
 

Why Is This An Important Role?

Nearly all of the essentials of modern life are welded or made by welded machinery. The Welding Inspector’s efforts to ensure the integrity of welds is therefore vital to the economic well-being of a nation and the safety of its people. A viable modern economy and the relatively high standard of living that it provides would simply not be possible without properly inspected welded structures, vehicles, and machines to generate, store, and transport food, fuel, and products to a multitude of individuals and businesses across the world.
 

What Career Opportunities Are Available to Welding Inspectors?

Welding Inspectors are an integral part of every industry that uses welding as a core process in the manufacture, construction, or fabrication of their products. Therefore, Welding Inspectors have the option of working in industries as diverse as aerospace, shipbuilding, automotive, railroad, electronics, defense, mining, construction, manufacturing, precision instruments, medical products, oil and gas, and nuclear energy. 

The comprehensive body of knowledge and skills required of Welding Inspectors also opens the door to other occupations in welding. For example, with some pedagogical training, Welding Inspectors are perfectly suited to the role of Welding Educator

The Welding Inspector’s organizational skills and familiarity with welding operations and standards also serve as a solid foundation for a position as a Welding Supervisor or Administrator. Those Welding Inspectors with especially good communications skills and business acumen can also use their extensive knowledge of welding processes, base materials, and welding consumables to branch out into Welding Sales and Service.
 

How Do I Get Started?

There is no single path to becoming a successful Welding Inspector. However, you will need a post-secondary degree or vocational instruction as well as on-the-job training to obtain the full range of knowledge and skills required to accomplish the technical and logistical aspects of the job. The AWS B5.1 Specification for the Qualification of Welding Inspectors lists the education and experience requirements as well as the duties and capabilities required of an AWS Certified Welding Inspector. Use this specification as a guide to help you determine the learning and employment opportunities that can best prepare you for entry into the field.

CAREER SPOTLIGHT

When British artist Anish Kapoor’s liquid mercury-inspired design, “Cloud Gate,” landed in the hands of stainless steel builders, more than 100 metal fabricators, engineers, technicians, and welders were employed to turn invention into execution. Standing 33ft high and 66ft long, the unique shape of the structure posed various challenges for the welders. They had to skillfully weld together 168 stainless steel plates, some weighing as much as 1,500 pounds, and leave no visible seams.
 

Named for its highly polished stainless steel plates that reflects the Chicago skyline, Cloud Gate underwent sophisticated processes that included laser scanning, hand grinding sheets, and even ceramic sandpaper. From 2004–2006, plates were fabricated and polished, suspension systems were built, and more importantly, seams were welded to near perfection.
 

Before the sleek, impressive Cloud Gate in Chicago became available for public viewing in 2006, the trustworthiness of its structure rested in the hands of a Welding Inspector. The bean-like shape of the structure could not be deemed complete until checks were made for any cracks or flaws that may cause the structure to shift or fall.
 

As a testament to the excellent workmanship performed by workers and welders alike, Cloud Gate was awarded with the Outstanding Achievement in Welding Award by the American Welding Society in 2007. 

ROLES & RESPONSIBILITIES

Welding Inspectors ensure that weldments and welding related activities comply with all applicable quality and safety criteria. 

To accomplish that objective they must perform many different tasks. In general Welding Inspectors perform inspections to determine if a weldment meets the acceptance criteria of a specific code or standard; monitor the welding process in order to ensure that the welders are qualified and that the equipment, materials, welding variables and welding conditions meet all applicable safety and quality criteria; and verify that records are maintained and conform to the requirements of the applicable standards. More specifically, the Welding Inspector’s duties can be summarized based on the order in which they are performed: (1) before welding, (2) during welding, and (3) after welding.   

Before: Before welding can commence Welding Inspectors must ensure that the correct iteration of the applicable code or standard is being employed. They must confirm that the Welding Procedure Specification, welder qualifications and engineer drawings are valid and that the welding equipment has been properly calibrated and maintained. Welding Inspectors must also verify the type, size, quality, and condition of materials and consumables before they can be used. Finally, the welding inspector must inspect the welding set-up, review the welding machine settings, and confirm that the work has been properly prepared.


During: During welding, inspectors will keep an eye on the use of consumables and make sure that welding variables such as  voltage, amperage, and travel speed comply with the WPS. They will also inspect the quality of individual weld passes, ensuring proper interpass cleaning and temperature, as well as the correct placement and sequence of each pass. In some instances, they may also need to check backgouged surfaces, monitor in process nondestructive tests, determine the suitability of welding operations based on weather conditions, or verify a compliance issue specific to the requirements of a particular project.


After: After Welding, Inspectors will visually inspect the weld, checking for dimensional accuracy and proper appearance. Welding Inspectors may also use other methods, such as radiographic or ultrasonic inspection, to identify possible defects. If a weld needs to be repaired, Welding Inspectors must approve the repair and re-welding procedures, monitor the re-welding process, and re-inspect the weld, to ensure compliance with the applicable codes or standards. In some cases the inspector is required to monitor post-weld heat treatment, or other post-weld work. After the process is completed welding inspectors must prepare inspection reports.

The duties of a Welding Inspector may also include:

  • review and approve welding procedures
  • verify welder and welding procedure qualification compliance
  • verify safety requirements compliance
  • develop visual inspection procedures
  • provide NDE inspection planning and scheduling
  • review contract requirements
  • review vendor proposal compliance
  • develop and implement an Associate Welding Inspector training program
