Weld JointWeld 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

by the other member from movement in one direction perpendicular to its thickness dimension”

A A non-butting member non-butting member is “a joint member that is free to is “a joint member that is free to move in any direction perpendicular to its thickness move in any direction perpendicular to its thickness dimensiondimension

Types of WeldsTypes of Welds

Many welds can be made by various types Many welds can be made by various types of joints of joints

Factors to be consider in choosing joint Factors to be consider in choosing joint geometry and weld types:geometry and weld types: accessibility to the joint for weldingaccessibility to the joint for welding type of welding process being usedtype of welding process being used suitability to the structural designsuitability to the structural design cost of weldingcost of welding
