Strength of a welded joint is defined by:Question 14Select one:a.Design of welded componentsb.Weld length and size of weld legc.Melting point of materials

The strength of a welded joint is primarily determined by the weld length and the size of the weld leg.

Step 1: Understand the question The question is asking what determines the strength of a welded joint.

Step 2: Analyze the options a. Design of welded components: While the design of the components to be welded can influence the overall strength of the structure, it is not the primary determinant of the strength of the individual welded joint. b. Weld length and size of weld leg: This is the most direct determinant of the strength of a welded joint. The longer the weld and the larger the size of the weld leg (the distance from the joint to the edge of the weld), the stronger the joint will be. c. Melting point of materials: The melting point of the materials being welded can affect the process of welding and the quality of the weld, but it does not directly determine the strength of the welded joint.

Step 3: Choose the correct answer Based on the analysis, the correct answer is b. Weld length and size of weld leg.
