1. Notations used in blueprints to convey welding instructions.
3. The depth at which the weld metal enters the base material.
5. Droplets of molten metal that are ejected during welding.
6. Stress applied to a material that pulls it apart.
7. A process of joining metals using a filler metal above 450°C.
8. Small holes or voids in the weld caused by trapped gas.
9. Tool used to smooth or shape metal surfaces.
10. The direction of electrical flow in the welding circuit.
11. The ability of a material to resist deformation.
