CHAPTER 12

Welded Joints

Chapter Objectives

  1. Differentiate between the types of welded joints.

  2. Describe planes of maximum shear stress in butt and fillet welds.

  3. Calculate normal and shear stresses developed in welded joints due to different types of axial load, twisting moment, and bending moment.

  4. Determine polar moment of inertia of welds about the axis of twisting moment.

  5. Determine moment of inertia of welds about the neutral plane of bending moment.

  6. Calculate torsional shear stress, at any point, in a weld, due to twisting moment.

  7. Calculate bending stress, at any point, in a weld, due to bending moment.

  8. Identify the critical region in weld and determine the resultant stress at that point.

  9. Calculate the safe endurance limit in shear, for ...
