Why is tensile strength an important property in welding?

It determines the amount of heat required
It indicates the weld's resistance to pulling forces
It measures the weld's thickness
It shows the welding speed

The correct answer is: It indicates the weld's resistance to pulling forces

Tensile strength is the amount of force a material can withstand before breaking. In welding, the weld needs to be able to withstand pulling forces and stresses. Therefore, the higher the tensile strength, the stronger the weld and the better it can resist pulling forces. Option A is incorrect because tensile strength is not directly related to the amount of heat required. Option C is incorrect because it is not measuring the weld's thickness, but rather its ability to withstand pulling forces. Option D is incorrect because tensile strength does not determine welding speed, but rather the strength and durability of the weld.
