Types of welds
Types of Welds

  • 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


Types of welds1
Types of Welds

  • There are nine categories of welds associated with weld symbols

    • Groove welds

    • Fillet Welds

    • Plug or Slot welds

    • Stud welds

    • Spot or projection welds

    • Seam welds

    • Back Or Backing welds

    • Surfacing welds

    • Flange Welds


Types of welds groove welds
Types of WeldsGroove 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


Groove welds square and double square groove welds
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


Groove welds v and double v groove welds
Groove WeldsV-and double V-groove welds

  • With thicker materials joint accessibility must be provided for welding to ensure weld soundness and strength


Groove welds bevel and double bevel groove welds
Groove WeldsBevel- 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


Types of welds u groove and double u groove
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


Groove welds j and double j groove welds
Groove WeldsJ-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


Groove welds flare bevel and flare v groove welds
Groove Weldsflare-bevel and flare-v-groove welds

  • Flare -bevel and flare-v-groove welds are used in connection with flanged or rounded member


Groove welds scarf
Groove WeldsScarf

  • Scarf is used for brazing


Groove welds
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
