Design Concept
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

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
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
