🔍 Key Concepts

• Review the parts of a standard welding symbol: reference line, arrow, basic weld symbol, dimensions, supplementary symbols, and tail. • Think about what information is normally written inside the tail on fabrication drawings (for example, process, procedure, or code references). • Compare choices that deal with what kind of weld vs. how or by what rules the weld must be made.

💭 Think About

• Ask yourself: when a designer wants to call out a specific welding process (like SMAW, GMAW) or a procedure number, where on the symbol is that usually placed? • Which option best matches information that can point to a code, procedure, or detailed instructions, rather than physical dimensions or orientation? • Look at the illustration: does the tail point to the joint, or is it more like a place to write notes? What does that suggest about its function?

✅ Before You Answer

• Eliminate any answers that clearly refer to size or direction, since those are normally shown elsewhere on the symbol, not in the tail. • Confirm which option refers to instructions/specifications rather than the geometric description of the weld itself. • Remember: if the tail is omitted, the weld can still be made; the missing information would most likely be extra specification or process details, not the basic shape or size of the weld.
