Relationships with occupations
Plastic welding is an essential knowledge of the following occupations:
Plastic welding is optional for these occupations. This means knowing this knowledge may be an asset for career advancement if you are in one of these occupations.
Medical device assembler: Medical device assemblers manufacture instruments, machines and appliances that can be used to prevent, diagnose or treat medical conditions. Medical devices can be non-electrical, such as tubes, needles, drainage sets and sterile pipettes, as well as electrical, such as pacemakers, MRI machines, and X-ray devices. Some may also work in the production of medical furniture such as hospital beds and operation tables.
Injection moulding operator: Injection moulding operators operate and monitor injection moulding machines, in order to cast products from thermoplastic materials. They regulate the temperature, pressure, and volume of plastic, according to pre-defined specifications. Injection moulding operators also remove finished products and cut-away excess material, using a knife or other hand tools.
Plastic products assembler: Plastic products assemblers fit and fasten parts and finished plastic products according to strictly-defined procedures. Plastic products assemblers may also cut and shape plastic parts using hand, power, and machine tools.
Metal product quality control inspector: Metal product quality control inspectors perform preventive and operational quality control on the metal products. They examine the materials at various stages to make sure it conforms to the desired standard, test the products, and send them back for repair if necessary.
Compression moulding machine operator: Compression moulding machine operators set up and operate machines to mould plastic products, according to requirements. They select and install dies on press. Compression moulding machine operators weigh the amount of premixed compound needed and pour it into the die well. They regulate the temperature of dies.
Welding inspector: Welding inspectors examine the connections and bonds between metals. They utilise visual tools and electrical instruments to inspect and ensure the quality and safety of connections. Welding inspectors ensure that all related welding activities, plans and materials follow the appropriate guidelines, in accordance with safety regulations. In addition to working in the field completing their examinations of welding projects, inspectors spend time in an office setting compiling their reports.
