The job of an assembler or fabricator ranges from very easy to very complicated, requiring a range of knowledge and skills. Assemblers and fabricators typically do the following:
- Read and understand detailed schematics and blueprints
- Use hand tools or machines to assemble wind turbine components
- Conduct quality control checks
- Work closely with designers and engineers in product development.
Skilled assemblers putting together complex machines, for example, read detailed schematics or blueprints that show how to assemble the machine. After determining how parts should connect, they use various electronic, robotic, computer, or hand tools to make adjustments to align and fit components together properly.
Assemblers are used extensively in the production of all turbine components. Manufacturing blades, for example, is labor intensive. Making the casings requires assemblers to interlace layers of fabrics and resins. Blades are usually made in two separate halves, which assemblers join together with an adhesive. After the blade has been formed, they sand and cover it with a protective coating.
Manufacturing techniques and changes in technology have transformed the manufacturing and assembly processes, moving away from traditional assembly line systems toward lean manufacturing systems where teams of workers produce entire products or components.
Manufacturing systems use robots, computers, programmable motion-control devices, and various sensing technologies. Advanced assemblers must be able to work with these new technologies and use them to produce goods. Despite increased automation, many parts still have to be put together and fastened by hand. For example, assemblers are responsible for putting the components together into a larger product. After determining how parts should connect, assemblers use hand or power tools to trim, shim, cut, and make other adjustments to align and fit components. After the parts are properly aligned, they connect them with bolts and screws or by welding or soldering pieces together.
Quality control is important throughout the assembly process, so assemblers look for faulty components and mistakes in the assembly process. They help to fix problems so no defective products are made.
It has also become more common to involve assemblers and fabricators in product development. Designers and engineers consult manufacturing workers during the design stage to improve product reliability and manufacturing efficiency. Some experienced assemblers work with designers and engineers to build prototypes or test products.
