Exam 9: Shielded Metal Arc Welding Plate

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

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.

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

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

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

Long arc lengths produce less spatter.

All welds start with a(n) ____.

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

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

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

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

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

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

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

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

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

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

Both of F3 E6010 and E6011 electrodes have ____.

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