Explore welding symbols with an overview of major welding processes and how to interpret arrows, lines, and tails for groove, fill, plug, and slot welds, including non-destructive testing basics.
Explore shielded metal arc welding (SMAW) basics, including flux and shielding gas to keep oxygen and nitrogen out of the weld puddle, plus base metal versus weld metal.
Explore the AWS welding symbol chart with a downloadable PDF resource, a printable reference for mastering welding symbols, arrow directions, and the associated letters.
Explore basic welding joint types - butt, lap, edge, corner, and T joints - along with budding members, non budding members, and splice members, including flange extensions and spliced joints.
Explore the basics of weld symbols and welding symbols, including their difference, eight elements, and how the reference line and arrow locate welds on metal fabrication drawings.
Learn to interpret fillet weld symbols and dimension fillet welds with equal and unequal legs. Understand arrow-side versus opposite-side positions and how vertical and horizontal leg sizes are specified.
Dimension fillet welds, handling equal and unequal leg sizes. Place size to the left of the symbol and length to the right, and note orientation and full-length cases on drawings.
Explore dimensioning of fillet welds, including length, size, and pitch for intermittent, chain, and staggered intermittent welds, plus weld contours and finishing, with practical examples.
Understand weld penetration concepts, including complete joint penetration through the thickness for full load capacity, and distinguish partial joint penetration and weld metal in welding methods.
Learn how preheating and post weld heat treatments control cooling, prevent cracking, and relieve residual stresses; explore staggered intermittent and backstep welding sequences to minimize distortion.
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.
