__________________ is a CSA flux cored wire classification - Answer -E491T-6M-H8
A common application of the FCAW process is: - Answer -Medium and Heavy Fabrication
A typical arc voltage range for shielded metal arc welding is: - Answer -16-40 volts
A welding arc consist of: - Answer -high current and a low voltage.
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.
Advantages of using robotic GMAW include - Answer -high productivity, comparatively easy to feed
the wire, and works for sheet metal and thicker materials.
An example of solid state welding (SSW) is: - Answer -explosion welding (EXW).
Argon is an inert gas. - Answer -True
Common applications of the GMAW process include : - Answer -welding of miscellaneous metals
(stairs, railings, etc.).
Constant voltage power sources are preferred for SMAW. - Answer -False.
Each electrode for SMAW must be imprinted with its classification. - Answer -True
Electrodes for flux cored arc welding: - Answer -can be self shielded or gas shielded.
Examples of physical properties that influence the GMAW arc are: - Answer -ionizing potential,
thermal conductivity, and specific gravity.
Flux cored arc welding is a process usually used in the semi-automatic mode, consisting of a: -
Answer -constant voltage power supply, a continuous speed wire feeder, a welding gun, and a
continuous filler metal electrode with a hollow core containing flux and other ingredients.
Flux cored wire electrodes are more expensive than gas metal arc electrodes. - Answer -True
Fluxes for submerged arc welding: - Answer -should be stored in a dry environment after opening.
Gas tungsten arc welding can be used with: - Answer -both AC and DC current of either polarity.
