NOC Code: NOC Code: 7237b Occupation: Welders and related machine operators
Occupation Description: Occupation Description:
Welders operate welding equipment to weld ferrous and non-ferrous metals. This unit group also includes machine operators who operate previously set up production welding, brazing and soldering equipment. They are employed by companies that manufacture structural steel and platework, boilers, heavy machinery, aircraft and ships and other metal products, and by welding contractors and welding shops, or they may be self-employed.

Document Use
  • Complete work cards identifying for each job your employee number, machine number and the time taken at each stage of the process. (1)
  • Read check lists when doing safety audits. (1)
  • Read welding specification charts to look up weld types by code and the specifications for each. (2)
  • Complete daily weld reports by entering codes for jobs, types of welds and time spent on jobs. (2)
  • Read labels on welding rods explaining their composition, or labels on gas bottles indicating their contents and safe handling procedures. (2)
  • Complete daily downtime reports recording when the line was started and stopped and the reasons for stoppages. (2)
  • Refer to Canadian Standards Association (CSA) standards books to locate colour codes and identification numbers for pipes. (2)
  • Read work orders showing the quantities and codes for the types of welds to be produced. (2)
  • Read control panel gauges and computer monitor displays that show operating data such as weld temperatures, typical pipe measurements used in the past, power entering the welding machine and inside and outside diameters. (3)
  • Read oscilloscope displays of sonogram readings to detect imperfections in pipes. (3)
  • Read assembly drawings to find the pieces needed and to know how the pieces should be assembled and the types of metal to use. (3)

Digital Technology
  • Monitor computer displays of order lists and pipe run quantities and dates in order to make operating decisions. (1)
Back to Top

Oral Communication
  • Communicate with helpers to arrange for them to hold pieces in the correct position for welding. (1)
  • Ask pipefitters to position pre-weld spacings in a way that makes the welder's job easier. (1)
  • Communicate with the overhead crane operator to co-ordinate the movement of heavy pieces weighing several tons, or to direct a forklift operator who is moving pieces into position for welding. (1)
  • Exchange information with co-workers about work assignments and welding specifications and techniques. For example, inform the machinist about the size and shape of metal pieces required. (2)
  • Receive verbal instructions from the foreman about production priorities and specifications and discuss production numbers and problems with the foreman. (2)
  • Comment on safe operating procedures at safety meetings. (2)
  • Talk with clients, when working on location, to clarify specifications, confirm any changes and ensure that the work environment is safe. (2)
Back to Top

Measurement and Calculation
  • Measure the setting distances on the welding machine to fit specifications for the particular weld being done. (1)
  • Calculate the number of coils of steel of a certain length that will be required to complete an order. (2)
  • Calibrate the micrometer against standard pieces of metal. (3)
  • Measure pipe diameter to the nearest thousandth of an inch and make adjustments based on feedback about the outside and inside diameters as the pipe comes out of the machine. (3)
Back to Top

Data Analysis
  • Monitor temperature, pressure and other gauges to make sure the weld conforms to specifications; combine data from the gauges with visual and tactile judgment to prevent problems. (1)
  • Make welding adjustments based on results from hardness tests and recommended specifications. (1)
Back to Top

Numerical Estimation
  • Estimate the centre of a length of pipe in order to place a secure hoist. (1)
  • Estimate the time needed to do a weld or set of welds and decide if the work can be done during the rest of the shift. (2)
Back to Top

Job Task Planning and Organizing
  • Welders and related machine operators generally follow work orders and verbal instructions from the foreman to know what production is required. They set up, organize and clean their own areas and prepare tools and rollers for changeover to new jobs. They sometimes prioritize jobs to maximize efficiency, taking into consideration the availability of cranes, the time it takes to prepare a new set-up, and the length of time remaining to complete a job before the end of the shift. They participate in planning for shutdowns. (2)
Back to Top

Decision Making
  • Decide when set-up requirements have been met and the line can be started. (1)
  • Constantly decide how to adjust welding machine settings to produce the desired weld. (2)
  • Make decisions about pipe quality. After completing a set-up, run the mill for a time, test sample pipe and decide when the product is acceptable. (2)
  • Decide whether to stop the mill because the equipment is unsafe or in order to make repairs. Balance the consequences of lost production during downtime against those of causing injury or producing low-grade pipe that cannot be sold. (3)
Back to Top

Problem Solving
  • A loss of hydraulic pressure at the mill has resulted in improperly formed pipe. Stop the operation and cut the pipe from the tooling. (1)
  • The line is not running properly after a shut-down. Make numerous adjustments until the line is producing good pipe. (2)
  • There are adverse environmental conditions while working on location. Assess the situation and make changes to the environment to ensure safe working conditions; for example, preventing gas leaks or wind problems. (2)
  • A hole is undersized due to excessive brazing. If the normal procedure of inserting a ceramic tube to keep the hole the correct size is not working, call upon the planner to rework the production plan. (2)
  • There are defective pipes. Identify the type of defect and check relevant factors, such as whether the machine has run out of flux, if machine settings need to be adjusted, if a tool is broken and needs to be changed, and if the quality of the steel is creating the problem. Solving the problem often takes experimentation and making incremental adjustments while the pipe is moving by at high speed. (3)
Back to Top

Finding Information
  • Get day-to-day information about production schedules and problems from co-workers. (1)
  • Ask the foreman about specific welds, what can go wrong and how to prevent breaking or failing. (1)
  • Consult procedure manuals, operation sheets and production schedules to identify work procedures and pieces to be assembled. (2)
