Welding Module 6: FCAW

Which of the following is not an advantage of the FCAW-G process?

• Up to (4) times greater deposition rate than SMAW

• Many steels are weldable over a wide thickness range

• Adaptable to both stainless and carbon steels

• Good for use outdoors in windy conditions

Which electrode classification identifies a filler metal that can be used in the overhead position?

• a. E70T-1

• b. E74T-9

• c. E73T-8

• d. E71T-5

Which of the following is Not true of the FCAW-S process

• a. Combines characteristics found in SMAW, GMAW, and SAW processes

• b. Is limited to welding ferrous and nickle base alloys

• c. Produces smooth, uniform welds

• d. The process produces slag free welds

The FCAW process has the capability of being used in what position?

• a. Flat position

• b. Horizontal position

• c. Vertical position

• d. All positions

In the AWS electrode classification E71T-1 the digit after the dash designates

• a. Tensile strength

• b. welding position

• c. chemical composition

• d. gas shielded

A Flux cored electrode used with an external shielding gas is NOT

• a. gas shielded

• b. semi automatic

• c. automatic

• d. self shielded

Of the two basic FCAW processes, one is self shielding, and the one uses an _______shielding gas.

• a. inert

• b. internal

• c. external

• d. ambient

When examining a spool of filler metal to determine if it is designed for flux cored welding, one should look for

• a. A 3,4,or 6in the electrode classification

• b. a T in the electrode classification

• c. an S in the electrode classification

• d. an F in the electrode classification

When employing a weaving technique with FCAW, a welder can eliminate problems with undercut by

• a. increasing voltage to increase the electrode burn-off rate

• b. Stopping momentarily at the end each weaving motion

• c. traveling faster to prevent melting away the edges of the joint

• d. Using a longer arc length to achieve a better spray transfer

In FCAW,the flux inside the tubular wire contains ingredients that

• a. Cause are flutter

• b. oxidize the weld

• c. provide shielding

• d. prevent slag formation
