  3. Five Basic Welded Joints Butt Joint Butt joint- a joint between two members aligned approximately in the same plane

  4. Different Edge Shapes and Symbols for some Butt-Joints

  5. Five Basic Welded Joints Corner Joint Corner joint - a joint between two members located at right angles to each other

  6. Some Different Edge Shapes and Symbols for Corner Joints

  7. Five Basic Welded Joints T-Joint T- joint - a joint between two members located approximately at right angles to each other in the form of a T

  8. Some Different Edge Shapes and Symbols for T-Joint

  9. Five Basic Welded Joints Lap Joint Lap Joint- a joint between two overlapping members

  10. Some Different Edge Shapes and Symbols for Lap Joints

  11. Five Basic Welded Joints Edge Joint Edge joint- a joint between the edges of two or more parallel or nearly parallel members

  12. Some Different Edge Shapes and Symbols for Edge Joints

  13. Proper terminology is needed in everyday job communication • Joint design identifies, “the shape , dimensions, and configuration of the joint • The individual workpieces of a joint are called members. • Three types members nonbutting member, butting member , and splice member

  14. A buttingmember is “a joint member that is prevented, by the other member from movement in one direction perpendicular to its thickness dimension” A nonbutting member is “a joint member that is free to move in any direction perpendicular to its thickness dimension

  15. A splice member is “ the work piece that spans the joint in a spliced joint Single-spliced butt joint Double-spliced butt joint with joint filler
