3. Weld Joint Depends on: Welding Location
Preparation needed, welding equipment used, and
Application
The basic weld joint consists of:
Butt joint,
Lap joint ,
T-joint,
edge and
corner

4. Terminologies
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
A butting member is “a joint member that is prevented, by the other member from movement in one direction perpendicular to its thickness dimension”
A non-butting member is “a joint member that is free to move in any direction perpendicular to its thickness dimension
A splice member is “ the work piece that spans the joint in a spliced joint

5. Types of Welds Many welds can be made by various types of joints
Factors to be consider in choosing joint geometry and weld types:
accessibility to the joint for welding
type of welding process being used
suitability to the structural design
cost of welding

6. Types of Weld groove, fillet, plug, slot, stud, spot, projection,
seam,
back or backing weld,
surfacing and
flange.
