SESK: Stuff Everyone Should Know · sesk.info/weld-joint-t-most-common
Which joint design is the most common in all applications, per Miller?
The T-joint.
- Edge joint
- T-joint ✔
- Lap joint
Why: A T-joint is formed when two pieces meet at about 90 degrees, with one edge welded to the flat face of the other.
Huh, didn't know that: Miller says T-joints are fairly easy to weld in flat, horizontal, vertical or overhead positions.
Why did the 30-60-90 triangle marry the 45-45-90 triangle? They were right for each other.
