Instrument Drawing, Reading and Understanding

What are the Goals?

Upon completion of this course, attendees will have a practical understanding of Engineering Drawings and would have covered the following topics:

• Learn the definition and characteristics of schematics of a schematic
• Identify various types of lines on schematics
• Demonstrate the ability to determine piping diagrams
• Describe a fluid-power system
• Demonstrate how to read and interpret a complete welding symbol

Who is this Training Course for?

The training course is primarily intended for individuals, with or without an engineering background, who need to be familiarized with standard methods of reading and interpreting Engineering Drawings.

The training course will offer background information that can be used to recognize standard Engineering Drawings which can then be used to plan effective installation and inspection of plants and equipment.

The training course will also benefit senior engineers who would like to increase or refresh their knowledge of reading schematics and symbols.
