A vertical weld position is basically a horizontal weld position rotated 90 degrees, making it so that the welder has to build their weld vertically from top to bottom or from bottom to top. The overhead position is considered the most difficult but is really just a flat welding position turned upside down. The system for classifying the eight weld types has eight corresponding codes that describe all the possible permutations:. Many plate welding certification tests are performed using groove welds because they stipulate that a groove weld certification also qualifies a welder to do fillet welds in the same position.
So, for example, if a welder passes the 4G welding certification test, they will also become certified for the 3G, 2G, and 1G positions. To become CWB certified for a position, a welder must pass that specific test. There are two ways to test the strength of a weld: destructive testing and non-destructive testing. Destructive testing typically involves putting a test plate coupon in a press brake to see if it comes apart. Non-destructive testing can be as simple as a visual inspection or can include more advanced non-invasive methods such as liquid dye penetration testing, radiographic testing, or X-rays.
The information contained in a WPDS shall include the type of joint, joint geometry, welding position, welding symbol, welding consumables, gas mixture and the welding parameters that are to be used in making a weldment.
The CWB process and certification provides an added level of confidence and assurance that the documentation, weld quality and knowledge level of fabricators is independently verified against the requirements of the standards, and thereby minimizes liability and public safety risks.

What are the significant differences in the requirements, because they all seem similar?
The short answer is that, at a high level, most countries approach welding in the same manner. However, as the saying goes, the devil is in the details.
However, when it comes to employing welding engineers and supervisors, only Canada and the EU require them to be licensed or certified in those roles. The U. It merely means that it is not driven by the standard itself. The concept of qualified fabricators and fabrication as an entity exists only in the Canadian and EU system.
Although the AWS offers a program in the U. See the charts for a visual representation of the critical differences in the three economies. In the U. However, in Canada, welders are retested every two years to ensure that their skills are up-to-date and they remain competent in the workplace. In the EU countries, this period is every three years. This is one of the major differences that John must now contend with and be accountable for should he choose to pursue a welding career in Manitoba.
A comparison of the general requirements of the Canadian, U. One major similarity that all three regions share is the ability to qualify a welder in what is known as the standard test assembly. This is a configuration that is not driven by what the company is doing but rather is based on a standard test that all companies can use. Approximately 95 per cent of Canadian welders have completed their qualifications on a standard test assembly.
The standard provides all requirements on chemical and mechanical properties of the electrodes and acceptable manufacturing tolerances. In addition, CSA Standard W48 requires the manufacturer to implement a quality management system that provides instruction on how to manufacture, inspect, pack, store, label and ship these welding consumables.
This provides clients with a welding qualification recognized around the world. The approval of welding procedures must be obtained before the commence of any work, as outlined within the applicable Standard s. This state-of-the-art facility provide welders the opportunity to practice and take a CSA welder qualification test.
