High-quality welds are the best way to ensure a successful metal fabrication project. Every single weld is important as they build on each other to ensure the final product’s structural integrity and longevity. Without sufficient welding quality control, mistakes can compromise the entire custom metal fabrication.

There are many ways that welding mistakes can cause disastrous and costly consequences. Even minuscule holes can invite rust, and poorly-fused welds can lead to breaks, eventually causing things like product failure or failure to meet OSHA industrial access regulations or industry-specific requirements.

Properly trained welders, along with a well-documented WPS program, can prevent project mishaps and delays.

Finding a Company

Finding a company that you can trust could be a challenge if you don’t know what to look for. Welding Procedure Specifications are a great way to determine the quality of the work you will receive. Having Welding Procedure Specifications is essential for every welding company because it maintains quality standards across every weld. It isn’t just a nice guide to follow. Under various international standards, a WPS is required to ensure a stable weld.

No matter how experienced your welding company appears to be, you shouldn’t rely on them to simply guess the best way to accomplish a specific weld. They should provide you with a list of specifications that guarantee their welders can execute an excellent weld in any situation. To maintain consistently high standards, you should look for a Welding Procedure Specification for every type of weld you require for your project.

What is a Welding Procedure Specification?

A Welding Procedure Specification, or WPS, is a formal written document describing standard welding procedures.

Like a recipe for welders, these procedures provide clear direction for welders to make quality products up to code and industry standards. They will include any details and information that are required to make the desired weld.

These are proven and tested procedures that include but are not limited to information such as the materials needed, the tools required, the processes to follow, the techniques they employ and finally, confirmation of the desired outcome.

A WPS goes beyond knowing you will get a great weld. Although a WPS will ensure the welded components meet design requirements, it can also help you determine what company you should go with when hiring someone to create your product. Knowing a company’s welders have skills that are in line with a particular WPS can give you peace of mind and ensure your product will pass inspection and do exactly what it should.

Why You Need Welding Procedure Specification

A company that has an established process to ensure their welders follow Welding Procedure Specifications means you know what you will get without having to see the finished product. Because the WPS should record all pertinent welding information, such as plate dimensions, material type, and welder and operator identifications, it is easy to guarantee the quality of the work.

Here at Yarbrough Industries, we hold our welders to the highest standard. We can provide Welding Procedure Specifications for the most common welding types, including MIG, TIG, welding of carbon steels, stud welding, and welding stainless steels for structural purposes.
