Welding3 fcaw #1

In the FCAW-S process, agents for degassing the weld are contained in the

• protective slag

• electrode metal

• flux

• nozzle

The proper electrode diameter for FCAW is related to the welding machine in use and the

• pipe diameter

• metal thickness

• metal density

• preheat temperature

Ear plugs are primarily worn by welders to protect their ears from

• sparks

• welding noise

• interruptions

• inert gases

Even a shielding gas can create a hazard if

• it is allowed to contact and mix with oxygen

• it is used for any welding process other than FCAW-G

• enough is released to displace oxygen in the area

• it is mixed with another shielding gas

The best way to prepare the bevel for FCAW V-groove joints, especially in stainless steel pipe, is

• with a cutting torch (thermal)

• by machining the bevel

• with a handheld grinder

• with a bench grinder

For FCAW, the polarity of the gun and workpiece leads depends on the application and the

• type of filler metal

• welding unit

• workpiece clamp

• base metal

When setting up FCAW equipment to provide the proper arc length, set the voltage

• to create a 1/2" (13 mm) arc

• to create a 1" (25 mm) arc

• according to the manufacturer's recommendations

• to ensure the arc does not contact the base metal

Higher welding heat, deeper penetration, and higher beads result from a higher

• voltage

• travel speed

• arc length

• current

The standard electrode extension for FCAW-S with 0.045" (1.1 mm) wire and an insulating nozzle is

• 1/4" to 3/8" (6 to 9.5 mm)

• 1/4" to 3/4" (6 to 19 mm)

• 1/2" to 1-1/2" (13 to 38 mm)

• 3/4" to 1-1/4" (19 to 32 mm)

The pipe axis position can vary by ±5 degrees from the nominal 45-degree angle in the

• 1G position

• 2G position

• 5G position

• 6G position
