Exam 4: Shielded Metal Arc Welding of Plate

The space between plates in a square butt joint is called the ____.

Electrodes with ____ are easier to control and are used for flat stringer beads and butt joints.

The ____ is the distance the arc must jump from the end of the electrode to the plate or weld pool surface.

A(n) ____________________ joint is made by tack welding two flat pieces of plate together.

An arc will jump ____.

A(n) ____________________ electrode angle pushes the molten metal and slag ahead of the weld.

Discuss the effects of setting the current too low or too high.

To correct a(n) ____ problem, a welder can use a smaller electrode at a lower current setting.

The ____ pattern works well on flat lap joints, all vertical joints, and horizontal butt and lap welds.

Large diameter electrodes may overheat the metal if ____.

The ____ pattern can be used if there is a large gap to be filled when both pieces of metal are nearly the same size and thickness.

Some electrodes may not remove the deposits ahead of the molten weld pool, resulting in ____.

A weld bead made at a(n) ____________________ amperage setting is wide and flat with deep penetration, produces excessive spatter, and is mostly hard.

​When should a welder change their body position?

​What may happen if too short of an arc length is used?

To prevent ____ use as little leading angle as possible.

Describe the proper body position for a welder.

The ____ weave pattern is often used for flat position welds on butt, tee, and outside corner joints.

____ have rutile-based fluxes with a thick slag left on the weld bead.

____ electrodes have a mineral-based flux with very heavy slag left on the weld bead.
