Document Use
  • Read safety signs and warnings in the production area. (1)
  • Read stickers identifying furnaces and batch numbers to ensure they match information shown on the inspection sheets. (1)
  • Complete forms to record the thickness and grade of metal and to record defect codes. (2)
  • Refer to pictures and descriptions in supply catalogues. (2)
  • Complete charts showing critical steel elements and the proportion of each element in the inspection sample. (2)
  • Read forms, such as production records and reject forms. (2)
  • Read test reports. (3)
  • Refer to computer-generated bar graphs and histograms which display data. (3)
  • Interpret graphs produced during ultrasonic inspection to determine if there are internal defects in products. (3)
  • Read production information presented in tables in order to convert the information to a graphic format. (4)

Digital Technology
  • Use a database. For example, use a database to keep track of production data, such as what products are being smelted in each furnace, when they will be cast and in what form ingots will arrive at inspection areas. (2)
  • Use a spreadsheet. For example, prepare test results spreadsheets. (2)
  • Use other computer applications. For example, track production processes on computer systems. (2)
  • Use word processing. For example, write memos to suppliers. (2)
  • Use communications software. For example, exchange notices and memos with co-workers on in-house communication systems. (2)
  • Use statistical analysis software. For example, use statistical programs to create graphs and charts as part of product analysis. (3)

Oral Communication
  • Talk to repair personnel about broken machinery and to delivery drivers about the pick-up and drop-off of test samples. (1)
  • Speak with lab technicians concerning variances between lab results and inspection findings. (1)
  • Talk to customers to inform them of specific tests which need to be performed. (2)
  • Interact with co-workers to co-ordinate schedules and to discuss production levels and problems, such as flaws in metals. (2)
  • Interact with supervisors to discuss lab results or quality concerns. (2)
  • Interact with operators to show them patterns of defects or trends outside of normal operating parameters. (2)
  • Give precise instructions to mill operators concerning detailed process changes. If communication is not clear, bad batches may be prepared resulting in considerable loss of time and money. (3)

Scheduling or Budgeting and Accounting
  • Prepare project budgets, itemizing all cost factors. (3)

Measurement and Calculation
  • Use a stopwatch to time turnover cycles. (1)
  • Calculate the quantity of alloy to add to make sure the product meets specifications. (2)
  • Measure dimensions of steel bars before and after cooling to determine the shrinkage. (2)
  • Measure quantities of trace elements in metal, using x-rays. (3)
Back to Top

Data Analysis
  • Compare numerical data from test results to established standards to draw conclusions about the sample. (1)
  • Calculate the average quantity of elements in metal mixes. (2)

Numerical Estimation
  • Estimate the amount of inventory stockpiled by "eyeballing" the storage areas. (1)
  • Estimate the area of a coil by observing its thickness and length. (2)
  • Estimate the amount of air-borne particulate when testing asbestos samples. (3)

Job Task Planning and Organizing
  • Inspectors and testers, mineral and metal processing, plan their work activities according to the overall production schedule of the plant. They generally prioritize their own tasks, with occasional reprioritizing taking place in response to special requests from shift forepersons. Inspectors and testers co-ordinate their activities with co-workers and supervisors to ensure that they are accurately taking into account the urgency of specific production runs and shipping deadlines. (2)
Back to Top

Decision Making
  • Decide what lab materials need to be ordered and when to contact the suppliers. (1)
  • Decide whether to secure and test additional samples to identify possible product defects. (2)
  • Decide whether to stop the production process to remove defective pieces. (2)
  • Make decisions about the meaning and importance of test results, such as whether test variations are significant enough to warrant remedial action. (3)
  • Decide when to alert others to unusual readings or trends, such as test results showing that concrete being shipped does not meet acceptable standards for tensile strength. (3)
Back to Top

Problem Solving
  • A customer's order is incomplete with respect to the quantity ordered and the quantity provided. Request additional pours or make up quantities from other orders if they are available. (1)
  • Cobbles, scabs, overfill on bars, seams or overlaps are discovered during an inspection. Talk to forepersons or operators to point out the defects and to discuss process changes which could resolve the problems. (2)
  • Equipment breakdowns have occurred. Troubleshoot the equipment, looking for blown fuses and low fluid levels. Call repair people if necessary. (2)
  • Samples are off specifications. Examine all the potential reasons, such as sample error, testing error or production error. Depending on the conclusion, it may be necessary to get a new sample or request that mill operators make changes in processes. (3)

Finding Information
  • Refer to customer databases to check the quality standards for specific orders. (1)
  • Find information in instrument manuals to correctly calibrate machines. (2)
  • Refer to industry publications and course materials for information on emerging technologies. (2)
  • Contact manufacturers, technologists or engineers to get specific data regarding concrete standards and tests. (2)
