Diploma

Major differences between a Diploma and degree:
Diploma in a layman language is a short term course generally up to 2 years which mainly focuses on training a person in a particular field.They are one of the quick and the best way to get a job as their course is based more on practicality. The importance of Diploma as compared to degree is relatively less.
DEGREE on the other hand, is a long term course which varies between 3-4 years for Bachelors, 2 years beyond Bachelor for master degree, depending on the course.Degree provide more in depth knowledge about a particular course then Diploma. Earning a degree opens more doors for opportunities as compared to Diploma. In fact, various career options require at least Bachelor degree.

Few the best short term courses after Diploma in Mechanical Engineering:
After completing the Diploma course in mechanical engineering, you may be looking to hone your skills and knowledge further to enhance the job prospects in this field. By pursuing the following courses, you can achieve your objectives.
Piping Design Course
If you are looking for a very job-oriented course that can make you ready for the industry then piping design course is the one you should go for. There are many institutes that offer short-term courses (usually 6 months) as well as long-term engineering courses. A lot of experts from this field of engineering recommend the candidates to have ample amount of knowledge in piping design and it can be acquired by opting for such a course. A lot of mechanical engineering concepts are a part of this course and hence it becomes more relevant for the engineers or professionals in this field.
Some of the short-term courses in piping include:
-Piping drafting and design certificate courses
-Pipe stress analysis certificate course
-Certificate courses in piping technology
By pursuing the course in the piping design, you can open the opportunity avenues in various industries including merchant navy, chemical industry, manufacturing units, and petroleum refineries. All these industries require piping specialists.
Robotics Course
Robotics is another advanced field of study for those who have completed the Diploma in Mechanical Engineering. In fact, a number of existing professionals pursue this course alongside their job to open doors to new opportunities. As the name suggests, Robotics is the study of the design, Science, and manufacturing of the robots. It is considered to be one of the most specialised subtopics of mechanical engineering. The robotics technology has evolved dramatically over the last few years. It finds its applications in a number of sectors and industries, thereby increasing the demands for the robotic engineers.
Some of the courses offered:
Automation engineering and robotics short term courses
-Certificate courses in mechatronics
-Crash courses in robotics and artificial intelligence
There are a lot of prospects for the robotic engineers in various sectors including microchip manufacturing companies, space research organizations, automotive industries, medical industry, military, and more.
-Certificate courses in Control Valve maintenance, selection and sizing
-Certificate course in advanced dynamics
