Why Welding Symbols Are Misunderstood More Than You Think

Welding symbols are often misunderstood not because they are overly complex, but because they are rarely taught as a complete system. This article explains why misinterpretation is so common, how it affects cost and quality, and why foundational understanding matters more than memorizing symbols.

How to Read Welding Symbols: The Basics

This blog post covers the basics of welding symbols. By understanding the building blocks of a welding symbol and the specifics of fillet weld symbols you can learn enough to understand over two-thirds of the welding symbols that will appear on prints. In this post you'll learn how to determine fillet weld size from a welding symbol. You'll also learn key notations such as the intermittent fillet welding symbol, staggered intermittent welding symbols, field welds and all-around welds.

Who is responsible for determining weld size?

In many fabrication shops, welders are often left to determine weld sizes due to a lack of clear specifications from design engineers or customers. This common practice frequently leads to overwelding, where fillet welds are significantly larger than necessary, wasting material, gas, and labor. Beyond the increased cost, overwelding also introduces quality issues like distortion and slag inclusions, paradoxically causing more failures than undersized welds. While structural welding codes provide minimum weld sizes to ensure adequate heat input, these often appear "too small" to welders, leading them to apply excessive weldment.
