True/false Flashcards
in semi-automatic or automatic processes the welder is required to work harder because of the greater demands on travel speed and current
false
the same equipment may be used for semi automatic GMAW, FCAW and SAW
true
wire should not be discarded on the floor because it can work its way into a filter screen on the welding power source
true
lower the density of a gas the lower the flow rate required for equal protection
false
more amperage is required to melt the wire the faster it is fed
true
slight changes in the welding gun and gold can be used to control the weld as the group spacing changes
true
the amount of reactive gas required to produce the desired effect is quite small
true
hot rolled steel has a thin copper layer which is formed during the rolling process
false
vertical down welds should never be used on thin Sheet Metal’s
false
the heat produced during gmaw welding is it sufficient to force 100% penetration consistently making it ideal for industrial applications
false
