Welders

NOC 7265

Introduction

Welders operate welding equipment to weld ferrous and non‑ferrous metals. This group also includes machine operators who operate previously set‑up production welding, brazing and soldering equipment.

Note: Each Essential Skills task is followed by a number in brackets, e.g. (2), which is the estimated complexity level for that task. Tasks are assigned levels, ranging from Level 1 (basic task) to Levels 4 or 5 (advanced task), and are listed in increasing order of complexity. The complexity levels may vary based on the requirements of the workplace.

Judge the performance of equipment, e.g. evaluate the performance of welders, shears and presses. (2)
Organize their work and set up work areas properly. They must gather materials and equipment and set up the equipment following established steps. Generally, welders are assigned work by their supervisors who inform them of the priority of tasks. There is frequent resetting of priorities by supervisors. For example, it is common for welders to be called away from one project to work on another. Although approximately 80 percent of welders’ work is done independently, they need to coordinate their work with others, including apprentice welders, fitters and other tradespeople. In a plant or shop setting, welders must share equipment, such as cranes, saws and grinders, with co‑workers. If equipment is not available when they need it, welders work on alternative tasks. (2)

May use Internet browsers and search engines to locate information, such as equipment and supply specifications. (2)

Additional Information

Other Essential Skills:

Working with Others

The majority of welders’ tasks are completed independently, but they must work with other team members, including fitters, other welders and supervisors to plan work, confirm measurements and calculations, assist co‑workers with tasks and schedule sharing of equipment. Journeypersons may coach and receive assistance from apprentices. They may also be partnered with workers from other trades, such as pipefitters, to co‑ordinate their tasks on projects so that steps are completed in the right order.

Continuous Learning

Welders are required by various codes, e.g. Canadian Standards Association (CSA) and American Society of Mechanical Engineers (ASME), to retake practical tests within a specific period of time. Study and practice may be required to prepare for these tests and employers typically allow time for this on the job. Various training programs, books and manuals are available through technical institutes and authorities, such as the Canadian Welding Bureau. Welders may also attend sessions hosted by suppliers about new products, such as grinding wheels, welding rods and gases. Employers also provide training that is specific to their companies, type of work and locations. Examples of company‑specific training include company policies, confined space entry, helicopter safety and H2S gas. Because innovations in consumables, such as gases and rods, equipment, welding applications and processes, are frequently introduced, welders must upgrade their knowledge and skills on an ongoing basis. Some welders pursue learning on their own time by doing things, such as researching technical information on the Internet.

Impact of Digital Technology

All essential skills are affected by the introduction of technology in the workplace. Welders’ ability to adapt to new technologies is strongly related to their skill levels across the essential skills, including reading, writing, thinking and communication skills. Technologies are transforming the ways in which workers obtain, process and communicate information, and the types of skills needed to perform in their jobs. In particular, the increasing use of computer‑assisted design (CAD), manufacturing and machining software will require welders to develop computer skills to keep current. Workers may be required to use specialized software to input data and operate plasma cutting machines, orbital welders and other computer‑controlled equipment, or access, modify and print technical drawings.

Technology in the workplace further affects the complexity of tasks related to the essential skills required for this occupation. Welders need the skills to use increasingly complex tools, such as computer controlled equipment and computer‑assisted design (CAD) software. In addition, digital technology can affect the complexity of numeracy‑related tasks. For example, workers can calculate costs, material requirements, conversions, electrical resistance, volumes, rates and offsets using Web‑based applications, specialized software and hand‑held devices, such as personal digital assistants (PDAs). While sophisticated welding techniques have increased the complexity of diagrams, electronic databases and keyword search functions make it easier to find information, such as specifications.
