Verified Questions & Accurate
Answers
1. The proportion of acetylene and oxygen in the gas mixture is
1:3
1:4
1:2
1:1
2. If a welder uses an electrode stickout of 25 mm while
performing gas shielded FCAW, what potential issues might
arise?
No significant impact on the welding process.
Increased risk of poor weld quality and arc instability.
Improved penetration and faster welding speed.
Enhanced safety and reduced spatter.
3. Describe how the sizing of tinners' snips can affect their
usability in welding practices.
The material composition affects the durability of the
,snips.
The weight of the tool influences the speed of cutting.
, The width of the blades affects the type of materials that
can be cut.
The overall length of tinners' snips determines
their leverage and control, impacting their
effectiveness in cutting materials.
4. Describe the significance of achieving a neutral flame
in welding and its composition.
A neutral flame is achieved by using excess oxygen, which
enhances the welding speed.
A neutral flame has no impact on the welding process and
can be ignored.
A neutral flame is created by using only acetylene, which
is sufficient for all welding tasks.
A neutral flame, composed of one part oxygen and
one part acetylene, is essential for effective welding
as it
provides the right temperature and prevents oxidation.
5. In a scenario where a welder is operating a crane and needs
to lower the boom, what signal should they use to ensure
safety and compliance with regulations?
arm position diagonal and thumb pointing sideways
arm position horizontal and thumb pointing down
arm position horizontal and thumb pointing sideways
, arm position vertical and thumb pointing up
6. Describe the significance of using a constant speed wire feeder
in welding operations.
A constant speed wire feeder allows for
manual adjustments to the wire feed rate during
welding.
A constant speed wire feeder ensures a consistent
feed rate of the welding wire, which is crucial for
maintaining stable arc conditions.
A constant speed wire feeder is less efficient than a
variable speed wire feeder.
A constant speed wire feeder is primarily used for cutting
metal rather than welding.
7. What is the voltage range typically used for short circuit
metal transfer in welding?
12-22 volts
10-15 volts
20-30 volts
25-35 volts
8. What is the wire feed set-up used with CV power sources in
welding?
Intermittent speed
