Introduction
The wire used in welding isn’t just any metal rod. It is an essential component that directly affects the strength, integrity, and safety of the structures that are being joined. For that reason, a set of stringent quality and performance requirements ensures that the wire you use in your welds is up to the task. Almost everything you do with a weld bead—especially in critical applications—can be connected either directly or indirectly to a certification standard. And there is a good reason for that. When you pick up a wire off the shelf, you need to know that it will perform.
Why Welding Wire Certification and Standards Matter
Certifying organizations and industry standards together have several critical reasons for being. They guarantee for welders a quality assurance that the welding wire they are using is composed of a specific chemical makeup and offers mechanical properties that enable a weld that is as strong as required. They also ensure the reliability and consistency of a welding wire, whereby one spool will work just like the next. Of far more importance, though, is safety. One of the premium reasons to use certified wire is that it helps reduce the risk of sending somebody home in an ambulance or worse. Good, reliable, and safe welding wire is proof against all these “bad things” that can happen when a weld fails:]]
Key Organizations and Standards
- The development and maintenance of vital welding wire certifications and standards are performed by several key organizations. The American Welding Society (AWS), for example, is responsible for many of these codes and standards. They publish certain classifications that are often used in the field and are very familiar to the welding industry. The AWS A5.18 makes up the carbon steel electrodes category, for instance, while the AWS A5.9 handles those with stainless steel. These codes cover not just welding wire but also the welders and the work in its entirety. The group also puts on a lot of training and certification programs.
- Another major player is the American Society for Testing and Materials (ASTM). They, too, put out a range of useful standards. For welding wire, the ASTM organization is particularly helpful in providing a very clear and internationally recognized standard. And then there’s the International Organization for Standardization (ISO). This group develops and publishes internationally recognized standards as well. Their standards are useful in creating a very clear and widely followed framework and are used for a wide range of welding procedures, including welding wire itself.
Common Welding Wire Certifications
- The certification of welding wire varies depending on the region, but it mostly adheres to one of three international standards: AWS, ISO, or the CE Marking directive in the European Union.
- Welding wire producers can apply for certification from the American Welding Society (AWS) to show that they have met the standards set by the organization. In the same way, they can do so for certifications from the International Organization for Standardization (ISO) or for certifications through conformance with the CE Marking directive in the EU.
How to Choose Certified Welding Wire
When you’re deciding on welding wire, there are a few things you want to do. You should look for certifications on the packaging or the wire itself. These could be from the American Welding Society (AWS), the International Organization for Standardization (ISO), or the European Conformity (CE) system. You may also want to ask for documentation from the manufacturer that says the wire complies with the proper standards. They should be able to supply it if they’re doing things the right way. Finally, you should consider the reputation of the manufacturer. If they’re known for low-quality goods, then maybe you should look elsewhere for your welding wire.
Conclusion
The certification and standards of welding wire aren’t just some bureaucratic hindrance. They are very important. They provide the safeguards for the quality, safety, and reliability of a weld. Having wire that is certified can mean a world of difference between failure, success, and even litigation in a finished product. Furthermore, customers or people who use products that have welds in them often trust that those welds will be good, strong, and reliable. That trust is critical to a manufacturer, and it should also be critical to a dealer in welding wire.
