Self shielded flux cored wires are: - answer better able to tolerate air currents.
What do the first two digits of a shielded metal arc welding electrode
classification indicate? - answer
How is the arc shielded when using the submerged arc welding process? - answer
By a blanket of granular flux
Welding power sources are broadly classified as: - answer constant current and

The FCAW wire electrodes, compared to GMAW wire electrodes, are: - answer
more expensive.
The submerged arc welding process: - answer
The primary control on a SMAW power source is: - answer current.
The SAW fluxes are: - answer classified in conjunction with the welding wire
forming an electrode/flux designation.
Electrodes for flux cored arc welding: - answer can be self shielded or gas
shielded.
, A wire designated by CSA standard W48 as an E491T-9MJ-H8: - answer results in a
weld deposit with a maximum of 8 ml of diffusible hydrogen per 100 g of weld
metal.
What are the four modes of transfer used in gas metal arc welding? - answer

What are examples of an F3 fast-freeze SMAW electrode? - answer EXX10, EXX11
The GMAW process uses __________ to shield the molten weld metal from the
atmosphere: - answer an external shielding gas
There are two types of fluxes used for submerged arc welding. These are: -
answer Fused and bonded
Each electrode for SMAW must be imprinted with its classification. - answer True
The main advantage(s) of using the GTAW process is (are): - answer a high quality
weld deposit and the ability to weld virtually all weldable metals.
Which of the following would NOT result in an increase in deposition rate with the
SAW process? - answer The use of DCEP
Advantages of using robotic GMAW include - answer high productivity,
comparatively easy to feed the wire, and works for sheet metal and thicker
materials.
