The Ultimate Guide To Choosing A CWB-Certified Welding Partner

October 23, 2025
CWB Certified Welding Partner

Nothing decides the success of your project like the quality of its welds. Whether you are retrofitting steel structures or managing a commercial building or an industrial expansion, you need to verify your welding partner’s capabilities and certifications before hiring them. 

 

Our advice? Always choose CWB-certified welding partners. Not only are they well-versed in different types of CWB welding, but their services are a hallmark of precision and professionalism. 

 

Weld Rich and Steel is a certified CWB welding company that offers its expert services throughout the GTA. With years of experience and a team of exceptional welders, we can walk you through the criteria it takes to find the perfect fit. Let’s begin. 

 

 

What Is CWB Certified Welding?

 

CWB welding refers to welding services approved by the Canadian Welding Bureau or CWB. This bureau is responsible for regulating and certifying welding companies to ensure they live up to CSA W47.1, W59, and other national standards, thus indicating the highest quality welds. 

 

With a CWB welding service provider, you can be sure that: 

 

  • The company’s welders require training and certification 
  • Their supervisors and inspectors are up to code
  • Only approved welding procedures are used, and they are well-documented
  • Materials and equipment used meet specified quality standards 

 

In a nutshell, when you hire a CWB-certified welder, you get to work with a skilled team that uses techniques and materials that are fully code-compliant from start to finish. 

 

 

Questions To Ask Before Finalizing Your Welder

 

Selecting the right welder is an easy task – provided you ask the right questions. Before narrowing down to your final choice, you should ask mobile welders in Toronto the following questions: 

 

 

  • What’s your certification scope?

 

Different certifications can mean different things. You need to find a welder whose certifications align with the requirements of your project. For example, certain welders may be certified for W47.1 – working with steel, while you may need W47.2 – working with aluminum. 

You should also check if they are willing to work on your site or if they offer only in-shop fabrication services. Furthermore, enquiring about their last CWB audit will give you confidence about the validity of their certification. 

 

 

  • Have you worked on similar projects in the past?

 

Even though a company is certified, they might not have any or minimal experience in your project type. For example, you may require a welder who can fabricate decorative stair railings, while one of the welders you have shortlisted might be adept at welding structural beams instead. 

 

This kind of project-to-welder incompatibility might yield less than satisfactory results. That is why, ask welders for references of previous projects they have worked on. If it matches your project type, you can definitely consider them – provided they have a CWB-certified team. 

 

 

  • Do you have strict safety and inspection checks in place?

 

This is something for you to evaluate. A good CWB welding service works on the principles of precision and safety. So make sure the partner you select has a dedicated safety and inspection program in place. This program should encompass pre-weld and fit-up checks, a well-documented welding procedure, and post-weld visual or non-destructive testing to determine the integrity of each weld.

 

 

Bonus: Watch Out For Red Flags

 

When it comes to mobile welders in Toronto, you should be cautious of the following red flags:

 

  • Unwillingness to provide proof of certification
  • Missing weld logs and inspection reports
  • Frequent scheduling delays and poor communication 
  • Absent post-installation support

 

Steering clear of such welders is wise. Make sure you choose welders who value professionalism and transparency.

FAQs

 

 

How often should a welding company renew its CWB certification? 

 

Maintenance audits are required every year, while a full re-certification is mandatory every 3 years to ensure the company remains compliant with CSA standards. 

 

 

Is a CWB welding certification applicable for both in-shop and mobile services?

 

Yes. However, a company has to apply for it. CWB’s certification program is made up of two divisions – Division 1 concerns shop fabrication, while Division 2 covers field welding. 

 

 

What happens if a project relies on non-CWB-certified welders?

 

The risks of using non-CWB welders include project delays, failed inspections, void insurance coverages, and legal penalties, among others.
