CAD draftsman can become a mechanical engineer, and the process includes: CAD draftsman-passing the exam after working for more than one year-junior engineer-passing the exam after working for more than three years-intermediate engineer-publishing papers, passing the exam and auditing-senior engineer. Mechanical engineers usually refer to professionals engaged in the mechanical industry. We often say that mechanical engineers refer to professional titles, that is, intermediate engineers. In addition, there is the mechanical engineer qualification certification of the Mechanical Engineering Society and the registered mechanical engineer of survey and design. Mechanical engineer refers to a person who is engaged in the mechanical engineering industry and has certain experience and level. Mechanical engineers are generally divided into three levels, junior mechanical engineers, intermediate mechanical engineers and senior mechanical engineers. Mechanical engineer usually refers to the general name of the third-level mechanical engineer, and can also refer to the intermediate mechanical engineer. There are many institutions in the mechanical engineering industry that issue different kinds of certificates. The following are introduced respectively: 1. International Registered Mechanical Engineer International Registered Mechanical Engineer Qualification Certification (ICME) is a professional engineer qualification certification carried out by the Institute of Mechanical Engineers (IME). The International Society of Mechanical Engineers marks that this qualification certification system for mechanical engineers evaluates professional and technical personnel through unified qualification examination, interview, professional ability evaluation, performance evaluation, recommendation by industry authorities and peer review. It belongs to the technical (or professional) qualification certification recognized by international peers. Junior international registered mechanical engineer (JICME) certification level (international registered mechanical engineer, senior international registered mechanical engineer (SICME) certification method is mainly issued by the office of the Institute of Mechanical Engineers. The office of Institution of Mechanical Engineers is: Institution of Mechanical Engineers China Headquarters Address: 22nd Floor, Inline Building, No.518 Shangcheng Road, Pudong New Area, China Hong Kong Headquarters Address: Room 2 16 ~ 2 18, Shui On Center, No.6-8 Harbour Road, Wan Chai, Hong Kong Address: Australian Institution of Mechanical Engineers Address: Kloc-0/2 halwestplace 465433 Engineer (Japan) Address: 5-9-20 マィィムビ 1252303 Institution of Mechanical Engineers Address: 50 1 Trade Building, Gangnam World Trade Center, Japan. Mechanical engineer Mechanical engineer is certified by China Mechanical Engineering Society, and evaluates professional and technical personnel through unified qualification examination, performance appraisal and peer review. Certification Grade Mechanical Engineer Professional Engineer Senior Mechanical Engineer Certification Method Anyone who applies for mechanical engineer qualification certification must pass the unified qualification examination and pass the examination, and must also take the professional engineer qualification examination organized by China Mechanical Engineering Society and pass the examination, and then the local branches will issue certificates.
