🔍 Key Concepts

• Review the standard weld joint symbols for single J-groove versus single V- and single U-groove preparations • Notice whether the groove preparation is on one plate only or on both plates (single vs double groove) • Pay close attention to the curved vs straight sides of the prepared edge in each A-column illustration on rows 3–6

💭 Think About

• Which A‑column figure between rows 3–6 shows one plate with a curved (radius) preparation blending into a flat land, while the opposite plate remains essentially square? • Which figures instead show straight bevels (V‑grooves) or curved preparations on both plates (U‑ or double‑J‑grooves)? • If you imagine cutting the joint down the middle, would the resulting shape look like a J on only one side, or would it be symmetrical like a V/U or a double‑J?

✅ Before You Answer

• Confirm that in a true single J‑groove, only one member is beveled with a radius, the other is left square • Make sure you are looking only at the A column options for rows 3, 4, 5, and 6, since the choices are 3A–6A • Eliminate any figure where the groove is symmetrical about the centerline or shows radius preparation on both plates, since those are not single J‑grooves
