Deck 9: Shielded Metal Arc Welding Plate

Question 1

The electrode angle is measured from the electrode to the surface of the ____.

A) metal
B) weld
C) pipe
D) joint

Answer 1

A

Question 2

Practice welds are grouped according to the type of joint and the class of welding electrode.

Answer 2

True

Question 3

Both of F3 E6010 and E6011 electrodes have ____.

A) mineral-based fluxes
B) rutile-based fluxes
C) cellulose-based fluxes
D) spatter-based fluxes

Answer 3

C

Question 4

A lot of practice is required to develop the speed and skill needed to prevent ____.

A) contaminants from forming
B) iron from rusting
C) the electrode from sticking to the plate
D) an excessive drop in voltage

Question 5

A very long arc length results in frequent shortening and sticking of the electrode.

Question 6

A trailing electrode angle pushes the molten metal towards the leading edge of the molten weld pool.

Question 7

Shielded metal arc welding (SMAW) or stick welding is the most commonly used welding process.

Question 8

A(n) ____ is made by placing the plates at an angle to each other.

A) tee joint
B) outside corner joint
C) butt joint
D) square butt joint

Question 9

Electrodes with the rutile-based fluxes are easier to control and are used for fillet, stringer beads, and ____.

A) edge joints
B) lap joints
C) tee joints
D) butt joints

Question 10

The straight step pattern can be used for stringer beads, root pass welds, and multiple pass welds in a few exceptional positions.

Question 11

All welds start with a(n) ____.

A) low temperature
B) low voltage
C) arc strike
D) fuel set at five psig

Question 12

Long arc lengths produce less spatter.

Question 13

The exact weave pattern for each weld is often the personal choice of the welder.

Question 14

A leading electrode angle pushes molten metal and slag ahead of the weld.

Question 15

Hard spatter is spatter that fuses to the metal surface and cannot just be wiped off.

Question 16

The selection of the correct size of welding electrode for a weld is determined by the skill of the welder, the thickness of the metal to be welded, and the ____.

A) qualified standard
B) size of the metal
C) schedule
D) type of fuel gas used

Question 17

Electrodes with mineral-based fluxes should be the first choice for a job.

Question 18

The ____ is made by tack welding two flat pieces of plate together.

A) tee joint
B) square butt joint
C) butt joint
D) outside corner joint

Question 19

A(n) ____ is made by overlapping the edges of the two plates.

A) square butt joint
B) butt joint
C) outside corner joint
D) lap joint

Question 20

____ are a temporary method of holding parts in place until they can be completely welded.

A) Tack welds
B) Plug welds
C) Fillet welds
D) Spot welds

Question 21

The ____________________ pattern is often used for flat position welds on butt, tee, and outside corner joints, and for buildup or surfacing applications.

Question 22

A straight weld bead on the surface of a plate with little or no side-to-side electrode movement is known as a(n) ____________________.

Question 23

To correct an overheating problem, a welder can turn down the amperage, use a shorter arc, travel at a faster rate, use a(n) ____________________, or use a smaller electrode at a lower current setting.

Question 24

The movement or weaving of the welding electrode is called ____________________.

Question 25

Higher ____________________ settings are required to maintain a short arc that gives good fusion with a minimum of slag inclusions.
