Understanding Welding Symbols. Welding symbols are the graphical tools, placed on engineering drawings and specifications, that product engineers and designers use to communicate the intent of their design to the people who are making and inspecting the products. Details like the type, shape, length, thickness, and location of the weld are all communicated through these welding symbols.

And like all symbols, without an understanding of how they work, they’re meaningless. But in this course, “Understanding Welding Symbols”, we show you how to read and interpret these symbols.

Metallurgist and Licensed Professional Engineer, Garry Pace is the instructor for this course. Over the past 20+ years, Garry has taught thousands of welders, weld inspectors, quality engineers, quality technicians, and other manufacturing professionals the fundamentals of welding, along with its procedures and specifications.

In this course, you will learn:

  • An overview of the major welding processes like GTAW, GMAW, SMAW, SAW and FACW
  • All the major weld joint types
  • The sections of the welding symbols … what they mean and why they’re important
  • All the terminology and concepts needed to master welding symbols
  • How groove and fillet welds are specified and dimensioned
  • How plug, slot, and stud welds are specified and dimensioned
  • An overview of nondestructive testing methods like ultrasonic, liquid penetrant, x-ray, and magnetic particle inspection
  • How required NDT methods are specified on blueprints
  • And much more!!

We’ve included in this course far more than just the dry theory. We’ve included real-life examples and practical applications that can only be learned through years of hands-on experience.

So if you’re looking to take your welding and metal working skills to the next level by incorporating the more technical aspects of your profession, then this is the class for you.
