Parts of a Weld: Inside and Out
A review game for students aged 16 to 18 on the main parts of a weld: face, leg, reinforcement, root, throat, penetration and heat-affected zone. Higher tiers ask students to explain, calculate and justify their answers.

Questions
- On the Surface (100): This is the exposed surface of a weld on the side where the welder did the work.
- On the Surface (200): Name the part of a fillet weld that is measured from the joint root along the base metal to the edge of the weld. Say how many of these a fillet weld usually has.
- On the Surface (300): Describe what face reinforcement is and where you would find it on a butt weld.
- On the Surface (400): Explain why too much face reinforcement can be a problem, even though it adds more metal to the joint.
- On the Surface (500): Compare a convex fillet weld face with a concave one. Explain how each shape can affect the throat and the strength of the weld.
- Hidden Inside (100): This is the part of a weld at the bottom of the joint, where the two pieces of metal are closest together.
- Hidden Inside (200): Name the shortest distance from the root of a fillet weld to its face, and say why welders care about it.
- Hidden Inside (300): Name the area of base metal that did not melt but whose structure was changed by the heat of welding. Describe one way it can change.
- Hidden Inside (400): Explain what penetration means in a weld and why incomplete penetration is dangerous.
- Hidden Inside (500): An equal-leg fillet weld has 10 mm legs. Calculate its theoretical throat and explain the method you used.
- You, the Welder (100): If you look at a finished weld from the side where you were welding, which part of the weld are you looking at?
- You, the Welder (200): If you were inspecting the back of a butt weld, which part would you check, and what would you look for?
- You, the Welder (300): Your supervisor asks you to make a stronger fillet weld. Which measurement would you increase, and how would you do it?
- You, the Welder (400): Imagine you are explaining a weld to a younger student. Describe a path from the root to the face and name the parts you pass along the way.
- You, the Welder (500): In your opinion, which part of a weld is the most important to get right? Give a reason based on strength or safety.
