  1. Welding Details

  2. Welding • Process of bonding metal pieces together • Work or metal pieces are melted along a common edge or surface and their molten metal allowed to form a puddle or pool liquid metal • The pieces are fused when the puddle solidifies

  3. Welding Process • 3 major • Gas welding • Electric arc welding • Resistance or spot welding

  4. Gas Welding • Uses a flame of an extremely high temperature that literally melts the metal • Also known as oxyacetylene • oxygen • acetylene

  5. Electric Arc Welding • Commonly called Arc Welding • Heat of electric arc used to fuse or cut metal

  6. Resistance (Spot) Welding • Metals held tightly together under pressure and subjected to electric current through the point of pressure • Electric current causes metals to heat up and fuse together

  7. Types of Joints in Welding 1--BUTT 2--CORNER 3--TEE 4--LAP 5--EDGE

  8. Commonly Used Types of Welds • fillet • plug or slot • spot • seam • groove • square • V • Bevel • U • J

  9. Basic Welding Symbols

  10. Welding Symbol Practice • Symbol placement for Fillet Weld

  11. Special Welding Symbols Field Weld • Weld All Around • Weld All Around would be used to to secure a pipe column to a plate • Field Weld is welding done at the job site

  12. Welds with Length and Spacing Size of Weld Spacing Length

  13. General Weld Callout

  14. Fillet Weld Callout Example • Weld arrow side Actual Weld Drawing Callout Size of Weld--NO larger than the maximum material thickness of the metals being joined

  15. Fillet Weld Callout Example • Weld other side Actual Weld Drawing Callout

  16. Fillet Weld Callout Example • weld both side Actual Weld Drawing Callout

  17. Groove Weld Symbol Callout Bevel weld 1/4” root opening arrow side V-grooved weld 1/4” root opening 45° groove angle

  18. Weld Finishes • A welded surface to be finished to a greater degree than just the structural weld a straight line or a convex arc is added to the weld symbol • Types of finished surface • M - machining • C - chipping • G - grinding

  19. Assignment • Review and coordinate the following consultant sheets into the contract documents – they must match the floor plans, sections, and elevations. • Sheets P-1, P-2, P-3, M-1, M-2, E-1, E-2, & E-3

  20. Welded Detail Drawing • Scale: your choice, as large as possible for “A” sheet • TS = True size of part • 3/8” bevel weld at side joints and 3/8” fillet weld at base plate/side joints of beam brackets • Profile sectioned items • Cutting Planes are assumed
