The five basic types of joints are: - 🧠 ANSWER ✔✔Edge, lap, butt, T, and corner.
T-joints are prone to distortion, though this can be minimized by - 🧠 ANSWER
✔✔tack welding at both ends and on both sides.
What is a surfacing weld? - 🧠 ANSWER ✔✔A weld that is applied to a surface,
not making a joint.

The term "Buttering" refers to: - 🧠 ANSWER ✔✔Creating buildup intended to
provide a buffer or transition for another surface weld.
For equal leg convex fillet welds, the measured leg size is the fillet weld size. - 🧠
ANSWER ✔✔True
The inclination of axis for overhead groove welds is - 🧠 ANSWER ✔✔0-80
