Weld Type Symbols

Weld Type Symbols

Weld type symbols are used to identify the type of weld required on a joint. The most common weld type symbols are:

1. Fillet Weld Symbol

• Represented by a triangle
• Indicates a weld that is approximately triangular in shape
• Can be used for lap joints, tee joints, and corner joints

2. Groove Weld Symbol

• Represented by a square or rectangular shape
• Indicates a weld that is used to fill a groove or gap between two parts
• Can be used for butt joints, edge joints, and corner joints

3. Spot Weld Symbol

• Represented by a circle
• Indicates a weld that is used to join two overlapping parts
• Typically used for sheet metal and thin plate applications

4. Seam Weld Symbol

• Represented by a long, narrow ellipse
• Indicates a weld that is used to join two parts along a continuous seam
• Typically used for sheet metal and thin plate applications

5. Flux Cored Arc Weld Symbol

• Represented by an "F" inside a circle
• Indicates a weld that is made using a flux cored arc welding process

6. Gas Metal Arc Weld Symbol

• Represented by a "G" inside a circle
• Indicates a weld that is made using a gas metal arc welding process

7. Gas Tungsten Arc Weld Symbol

• Represented by a "GT" inside a circle
• Indicates a weld that is made using a gas tungsten arc welding process

8. Shielded Metal Arc Weld Symbol

• Represented by an "S" inside a circle
• Indicates a weld that is made using a shielded metal arc welding process

9. Submerged Arc Weld Symbol

• Represented by an "SA" inside a circle
• Indicates a weld that is made using a submerged arc welding process
