What’s Your Future as a Welder?

Most workers in this occupation work full-time, sometimes in shift work, usually indoors. Those with the ability to work with high-technology welding applications may have better employment opportunities. The bulk of employment opportunities are predicted to occur in the non-electrical, machinery, construction and metal-fabricating industries. Some workers will become self-employed. Examples of companies that employ welders include: Fabricating shops; Manufacturers of structural steel and platework; Construction industries; Boilers; Heavy machinery contractors; Aircraft contractors; Ship building and other transportation contractors; Specialized welding shops.

3. You already know what sort of skills you should have to be a welder. Now think of the answers to the following questions:

1. How long should a person be trained to become a skilled welder?

2. Do you think that a welder should be able to use all kinds of welding?

3. What is more interesting to you personally: welding techniques, welding inspection (other)?
