When the flux-cored wire does not require an external shielding gas, the process is called _____________________. - self-shielding FCAW or FCAW-S If the tongue and lace area of your safety shoes is exposed, you should wear _____________________. - leather spats or chaps When possible use powered extraction systems that are designed to remove ___________________. - welding fumes Modes of GMAW metal transfer include: - spray transfer, globular transfer, and pulsed transfer Pulsed transfer (...

In the GMAW process, a composite-cored electrode (powdered metal inside core) is used for the ____________________. - filler metal When gas welding, you must always wear a _________________ or __________________, and the lenses must be an approved shade. A properly tinted welding hood is best for all forms of welding. - face shield or safety glasses Use ____________________ systems to remove welding fumes. - powered extraction When preparing a welding area, set up ____________________. - w...

A shielding gas can be generated entirely from the ____________________ in the electrode core. (self shielded FCAW-S) - flux If a hard hat is required for the environment, use one that allows the attachment of ____________________. - rear deflector material When preparing to practice welding, set up ____________________ around the welding area. - flash sheids V-groove weld coupons must be beveled at _________to___________degrees for carbon steel or low alloy plate. - 30 to 37 1/2 Slower ...

If you see the label TIG on a welding machine, that machine is considered to be what kind of welding machine? - GTAW During the GTAW process, UV radiation in the atmosphere near the weld can ionize ___________________. - oxygen GTAW is most commonly performed using ___________________. - direct current electrode negative (DCEN) High voltage, high frequency current creates a very stable arc that is able to jump a gap of about _____________________. - 1/2 inch Advanced features and control...

Since there is no flux in GTAW welding, ____________________. - no postweld cleaning is necessary When a hard hat is required while welding, use one that allows the attachment of _____________________. - rear deflector material and a face shield. Approved fire extinguishers must be available before ____________________. - any welding or cutting Clean the steel plate before welding to remove mill scale, because the direct current electrode negative (DCEN) used in GTAW has __________________...
