Q

Describe a V-Groove

A

The 2 surfaces are machined flat and smooth at an angle (bevel). When the 2 surfaces are placed together, they form a single “V” shape. In some cases, the root of the “V” does not extend to the bottom surface of the material.

Q

Describe a Double V-Groove

A

The edges are beveled from both sides. When placed together, the 2 pieces form a “V” on both sides. Both sides are then welded.

22
Q

Describe a Bevel Groove

A

One edge is beveled and the other is flat

23
Q

Describe Square Groove

A

Both edges are flat at 90 degrees. This creates a bottomless groove, formed by slight separation of the pieces

24
Q

Describe U-Groove

A

Both edges are machined with a curvature that produces a “J” cross-section. When placed together they form a groove with a “U” contour

25
Q

Describe Doube U-Groove

A

Each piece is machined with a “J” contour from both sides. When brought together the edges form a “U” groove on each side. Welding is done on both sides.

26
Q

Describe J-Groove

A

One piece is machined from one side only with a “J” contour, while the other is flat at 90 degrees

27
Q

Describe Scarf Groove

A

The joining edges are machined flat, but at an angle

28
Q

Describe Flare-V Groove

A

2 surfaces with curved profiles are brought together to form a weld groove with curved sides

29
Q

Describe Flare-Bevel Groove

A

One edge has a curved profile, while the other is flat at 90 degrees

30
Q

What is the (numeric) term for this weld?

A

Single Groove

31
Q

What is the (numeric) term for this weld?

A

Double Groove

32
Q

Label this:

A

a. Weld Depth
b. Root Opening

33
Q

Label this:

A

a. Reinforcement
b. Melt Through

34
Q

Label this:

A

a. Groove Angle
b. Groove Depth

35
Q

Weld Root

A

The bottom edge of a weld or the deepest point of a weld

36
Q

Root Opening

A

The space intentionally left between joined surfaces before welding which is also visible when the weld does not fully penetrate the material

37
Q

Weld Depth

A

The distance from the surface of the material to the root of the weld

38
Q

Reinforcement (Welding)

A

The specified height of the weld above the surface of the material

39
Q

Melt Through (Welding)

A

The thickness of weld, measured from the root of the weld to the material surface, when the root extends beyond the surface

40
Q

When are Fillet Welds used?

A

When the configuration of the joining pieces creates 2 weld surfaces, which are 90 degrees to each other

41
Q

Fillet Weld

A

Weld deposited into a 90 degree joint and assumes a somewhat triangular cross-section.

42
Q

All-Around/Box Weld

A

A continuous fillet weld, used to weld a vertical post to a flat plate, that travels around corners

43
Q

What kind of Fillet Weld is this?

A

All-Around/Box Weld

44
Q

Label this:

A

a. Throat
b. Toe
c. Leg

45
Q

When are Staggered Intermittent Fillet Welds used?

A

Where the strength of the joint is not crucial or where complete sealing of the joint is not necessary

46
Q

What must a welder know in order to successfully produce Staggered Intermittent Fillet Welds?

A

The lengths of the individual welds and the pitch.

47
Q

Pitch (Welding)

A

The distance between the mid point of adjacent welds.

48
Q

Are intermittent welds always staggered?

A

No

49
Q

Label these measuerments:

A

a. Pitch
b. Length

50
Q

Plug and Slot Welding

A

The joining of 2 relatively flat pieces with a series of small welds that are deposited into drilled plugs or machined slots in 1 piece.

51
Q

When Plug and Slot Welding, what characterizes the piece with the holes and the holes?

A
  1. Piece is usually thin
  2. Sides of the hole may be bevelled or perpendicular
52
Q

How does a Welder know how deep the welds must be within the plugs and slots when Plug and Slot Welding?

A

Information provided on the Welding Symbol

53
Q

What type of weld is this?

A

Plug Welds

54
Q

What type of weld is this?

A

Slot Weld
