1. Weld and Joint Geometry

3. Types of Welds accessibility to the joint for welding
Numerous welds can be applied to the various types of joints
Considerations when 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

13. Groove Welds
A groove weld is “ a weld made in a groove between the work pieces”
There are eight types of groove welds
Square-groove
Scarf
V-groove
Bevel-groove
U-groove
J-groove
Flare-v-groove
Flare-bevel-groove

14. Groove Welds Square and double square-groove welds
Square-groove welds are the most economical to use, but are limited by thickness of the members
Welds for one side are normally limited to a 1/4 inch or less

15. Groove Welds V-and double V-groove welds
With thicker materials joint accessibility must be provided for welding to ensure weld soundness and strength

16. Groove Welds Bevel- and double-bevel-groove welds
Bevel- and J- groove welds are more difficult to weld than V- or U- groove welds
Bevel welds are easier in horizontal

17. Types of Welds U-groove and Double U-groove
Welds in using J- and U-grooves can be used to minimize weld metal
These welds are very useful in thicker sections

18. Groove Welds J-and double-J-groove welds
J-groove are more difficult to weld because of the one vertical side (except in horizontal)
J-and U- are used when economic factors outweigh the cost of edge preparation

19. Groove Welds flare-bevel and flare-v-groove welds
Flare -bevel and flare- v-groove welds are used in connection with flanged or rounded member

20. Groove Welds Scarf
Scarf is used for brazing

26. Groove Welds
Their names imply what the actual configurations look like when viewed in a cross section
Single groove welds are welded from only one side
Double groove welds are welded on both sides
Groove welds in many combinations are used selection is influenced by accessibility, economy, adaptation to structural design
