100

Which of the following electrodes would be the best choice for medium- or high-carbon steels

E7018

100

The harmful oxygen and hydrogen present in the atmosphere surrounding a molten SMAW weld is pushed away  by the

gaseous shield of carbon dioxide

100

_________is the ability to verify that a procedure has been followed by reviewing the documentation step-by-step

Traceability

200

which American Welding Society (AWS) specification (s) cover the most common electrodes for welding carbon (mild) steel and low-alloy, high strength steels?

A5.1 and A5.5

200

Welding in vertical and overhead position should not be attempted with SMAW electrodes larger then 3/16" in diameter unless the electrode is classified as

low-hydrogen (F4)

200

The exposure time for low-hydrogen electrodes, per AWS standards, typically ranges

1/2 hour to 4 hours

200

Welding current is transferred from the electrode holder and into the workpiece through the 

wire core of the electrode

200

An electrode that is carefully manufactured to contain little or no moisture is called a (n)

Low-hydrogen electrode 

300

The rated tensile strength of the deposited weld metal from an E7018 electrodes is 

70,000 psi

300

After a sealed container of low-hydrogen SMAW electrodes must be stored in an appropriate oven at a minimum temperature setting of 

250

300

All-position electrodes that provide deep penetration belong to which electrode group?

F3 fast-freeze

300

A container that is closed airtight is said to be

Hermetically sealed

300

A (n) ______ is a metal that has had other elements added to it that substantially change its mechanical properties

Alloy

400

All SMAW electrodes used for code-governed work must have the AWS classification number printed on them as well as on the

Container in which they are shipped

400

Low-hydrogen electrodes that have been exposed to liquid water should be 

disposed of 

400

The traceability requirement of filler metals vary according to

the client requirement and job specifications 

400

The process in which water vapor from the atmosphere returns to its liquid state is called

Condensation

400

The part of a base metal that has been altered but not melted by the heat is called the 

Heat

500

Electrodes with powdered iron in their flux belong to the 

fast-fill (F1) electrode group

500

How many times can electrodes that have exceeded their maximum period exposure be dried

once

500

The purpose of the specifications written by the American Welding Society (AWS) is to set standard that all manufacturers must follow when manufacturing

welding consumable 

500

Welding upward  or downward is called

Vertical welding

500

___________is the ability of a material to resist breaking at point where stress is concentrated

Notch toughness
