Final answer:
The geometry of a tee joint allows for a larger weld than butt or lap joints due to the larger surface area available for welding, providing a stronger and more reliable connection for materials under stress. correct option is 1.
Step-by-step explanation:
The geometry of a tee joint enables a larger weld to be made than either the butt or lap joint. Tee joints are a common type of joint used in welding where two pieces intersect at a 90-degree angle. This configuration provides a large surface area for the weld, which often results in a stronger and more reliable connection.
The increased surface area allows for more filler material to be used, thus creating a larger weld. This is particularly beneficial when joining materials that are subject to significant stress or loads.
Compared to butt and lap joints, which might have less surface area for welding depending on the thickness of the material and design, the tee joint's design inherently allows for more welding filler material and thus a stronger bond.
