Exam 14: Flux Cored Arc Welding

The upside to higher welding speeds is that FCA welding is highly productive and very cost-effective.

You can find out what the kerf width is for a torch by making a sample cut in scrap metal and measuring its ____________________.

The wire speed control dial can be advanced or slowed to control the burn weld size and ____.

The higher the wire feed speed, the higher the welding current.

Some welders have to make welds in very restricted spaces using a mirror.

The ____ can be used to join thinner plate sections to make a thicker section.

The effect of having too high or too low an arc voltage is the same of having too high or too low a wire feed speed.

A gas welding rod tip can be flattened into a(n) ____________________ shape as a spacer to adjust the root opening.

Horizontal butt welds are more difficult to perform than most other welds.

Using the wrong electrode extension for a specific electrode can result in very poor welding with slag inclusions, porosity, and a lack of ____.

The tee joint is often used to join structural shapes such as an angle iron to itself at a ____ angle.

With FCA welding, the voltage is set on the welder, and the amperage is set by changing the ____.

____ are used to make a weld through the surface of a plate to a plate located directly behind the top plate.

____ is the type of rusting that occurs when water seeps between two tightly fitting surfaces.

One of the major factors that affect FCA welding is that the welding wire is being fed out at a low speed.

Setting up the arc voltage and amperage for FCA welding is different from setting it up for GMA welding.

The electrode extension is referred to as ____________________.

When FCA is used, welds may stop in a corner.

Some types of FCA welding electrodes need ____ electrode preheating.

There are two commonly used shorter timed tests to reduce the wasting of electrode. One uses 15 seconds, and the second test uses ____.
