Welding is the trade you want to be in, especially in Canada. Not only is the skill in high demand, but highly qualified welders cannot be easily replaced. At a national level there are upcoming projects that will heavily rely on welding and large fabrication, and meeting the welder demands for these projects over the next few years should prove to be a challenge.
A skilled welder is classified by the level of training they’ve received; obtained at trade school, or through a union program or possibly a college or university. Those who take part in a qualified program/course can expect to receive proper training to acquire the technical and technique they need to be classified a skilled welder. However, different courses and programs may deliver content in a different way. As for how a welder’s skill is measured, they need to take part in practical testing. An example of this is the CWB (The Canadian Welding Bureau) Welder Qualification.
