Exam 4: Shielded Metal Arc Welding of Plate

____ electrodes have a forceful arc with little slag left on the weld bead.

Why is the travel and work angle important?

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

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

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

What two terms do welders often use interchangeably when speaking about welding current?

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

How can a consistent arc length be maintained?

A(n) ____________________ joint is made by tack welding one piece of metal on another piece of metal at a right angle.

If the current is set too high, the electrode covering is discolored more than ____ from the end of the electrode.

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

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

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.

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

Describe the distribution of heat on both plates during a tee weld.

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

____ welds are more difficult to perform than most other welds.

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

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

Describe the proper body position for a welder.
