What Does a Mechanical Drafter Do?

Mechanical draftsmen mainly refer to those who use drawing instruments and equipment to draw mechanical technical drawings based on engineering or product design schemes, sketches and technical descriptions. Mechanical draftsmen are roughly divided into four levels: junior, intermediate, senior, and technicians. ^[1] Job responsibilities of mechanical draftsmen: design of mechanical equipment, including steel structure design, pipeline structure design, and design drawing output; writing related technical documents.

Divided into theoretical knowledge examination and skills operation assessment. Theoretical knowledge test uses a closed-book written test method, and the skill operation test uses an on-site practical operation method. Both the theoretical knowledge test and the skill operation assessment are implemented on a 100-point scale, and those with a score of 60 or more are considered qualified. The technician must also conduct a comprehensive review.
