WELD JOINT

WELD JOINT

There Are 5 Basic Joint Types In Welding

• Butt joint: Two materials are in the same plane, joined from the edges.
• Corner joint:The corners of two materials form a right angle and joined.
• Lap joint: Two parts overlaps.
• Tee joint: One part is perpendicular to the other, making a T shape.
• Edge joint: Edges of the two materials joined.

TYPES OF WELD

• Fillet weld: Used in T joints,corner joints, lap joints. 
• Groove weld:Used in butt joints. 
• Plug weld: Used in lap joints. 
• Slot weld: Used in lap joints. 
• Spot weld: Used in lap joints. 
• Seam weld: Used in lap joints. 
• Flange weld:Used in edge joints. 
• Surfacing weld:Not a joining process, it is used to increase the thickness of the plate, or provide a protective coating on the surface.

Weldability is the ease of a material or a combination of materials to be welded under fabrication conditions into a specific, suitably designed structure, and to perform satisfactorily in the intended service.
