P1 s19 mitchell secrist OPEN NOTE
1. What are the two types of
welding
testing? destructive and non destructive
2. What are the two types of destructive
tests? workshop tests and
laboratory tests
3. List two reasons why testing is
necessary? Defects occur during
welding which affect the quality and hardness of the plate. lack of skill by
welders causes defects
4. List 5 workshop
tests. tensile bending hardness impact
fatigue
5. Describe tensile testing… material is sectioned and edges rounded of
to prevent cracking. punch marks made to see elongation
6. Describe Bend Testing… shows physical condition of the weld
and determines weld efficiency tensile strength ductility.
7. What are the bend test
steps?Bend through 180O the specimen
should be a minimum of 30mm wide The fulcrums diameter is 3x thickness of the
plate
The bottom rollers have a distance of the diameter of the former +2.2
times the thickness of the plate. Upper and lower surfaces ground or
filed flat and edges rounded off.the tests should be one against the root
-another against the face ,and in some cases a side bend.
8. List the formulas for a Root Bend
test. d=3t / arrow going
down d+2,2 t
9. List the formulas for a Face Bend
test… d=3 t
arrow up d+2.2 t
10. List the two types of impact
tests… charpy and izod
11. What products were sold in our pass production project?
keychains
12. Which sales rep sold the most product? dillan because he cornered
the lp market
13. If you were to start a company and mass produce a product, what
would you produce? i would produce whatever sold.
14. What
are three applications of using plasma cutting?
15. Define dross The resolidifiedmetal on the bottom or top of the cut. Dross
formation and it’s condition is determined by many factors:•travel
speeds•amperage•gases used•type and thickness of metal•torch-to-work
distance•material surface coatingsCutting
16. Define Kerf: opening created by the metal removed by the plasma arc the
width of the kerf is determined by amperage gases nozzle orifice size.
17. . List 4 benefits of torch shielding? Nozzle is protected by an
electrically isolated shield•Significantly reduces double arcing•Prolongs parts
life•Facilitates drag cutting and template tracing•Dramatic improvement in
nozzle lifeTorch
18. When
the pilot arc is brought into contact with the workpiece
it will attach to
the work piece. The __plasma________ arc melts the
metal, and the high velocity gas removes the molten material.

20. What does OCV stand for? open circuit voltage
21. List
the sequence of events that takes place with plasma
cutting. •Power Supply•Start Circuit•Gas Flow Control•Torch
22. Explain
the functions of the torch. The torch is where
the arc is generated
23. Explain
what the gas console does? Houses metering and
solenoid valves for shield and plasma gases. The gas console interfaces with the
plasma and shield gas supplies, the RHF Console, the Motor Valve Console and the
Power Supply.
24. Define power supply.Produces constant current pure DC
output.•Houses the control circuitry for the proper sequencing of the entire
system.•Houses the cooling system for the torch
25. What are the four major system components of every plasma cutting
system? –start signal–torch starting mechanism–gas flow–pilot arc–arc
transfer
26. Regarding Plasma cutting, what does the nozzle and electrode do?
Electrode and nozzle are in contact or “shorted”before the gas reaches the
tor
27. What
does the torch do with the plasma cutter? generates
the arc
28. Define Plasma Cutting. Plasma cutting is a process that utilizes an
optimized nozzle orifice to constrict an electrically charged ionized gas
29. What is a natural example of plasma? lightning
30. Explain ionization of gases. when gases are superheated they become
ionized and are electrically conductive.
31. Define steam. when water is heated into a gase

35 . List 4 types of cutting methods. punch press on an x y
table
use a robotic arm hd technology
36. What
is the perfect cut?
37. What is Plasma? the 4th state of matter when you superheat gas and
it becomes ionized and electrically conductive
38. What
is essential to know to achieve optimum performance
of your plasma cutting system? understand how it operates
39 . What are three applications of using
plasma cutting? na
40 . What are lag lines? These are the ripples on the cut face or
surface
41. Safe use of Oxy-Acetylene operations requires what? clear
understanding of oxy fuel welding and fundimentals of combustion
42. What is one of the most dangerous pieces of welding
equipment? oxy fuel welder
43. Accordingto OSHA, what are the odds of dying from working with gas
equipment over a life time? 4/1000
42. What are the three basic elements in the triangle of
combustion?
FUEL OXEGEN KINDLING TEMPERATURE
44. Is oxygen
flammable?NO
45 . How is oxygen shipped? Oxygen is shipped as a
non-liquefied gas at pressure above 2000 psi, and also
as a cryogenic gas at
pressures below 200 psi.
46. What is the value in knowing kindling temperatures of materials?
Materials with a
low kindling temperature, in the presence of oxygen and
minimal heat, can ignite
spontaneously. When certain fuels burn, whether
liquid or gas, their respective
rate of burn is so rapid that we refer to
the burning process as an explosion.
47. What is the difference between burning rate, temperature output and
BTU output? BURNING RATE IS IS HOW FAST IT BURNS TEMPERATURE IS HOW HOT IT
BURNS. BTU IS THE ENERGY IT PRODUCES
48. Why is it important to keep cutting torch and other gas cylinders
secured? Securing cylinders is important to prevent damage to the high
pressure valve, in the event the cylinder were knocked over, allowing the high
pressure contents to escape in an uncontrolled fashion.
49. What is the maximum regulator pressure setting when using
acetylene? 15PSI
50. Whatare four types of regulator burnouts (RBO’s)to be concerned
about when using a cutting torch? DUST OIL OXEGEN DISSOCIATIVE GAS MIXED
GAS

the operator? rose bud tip
52. Whatare the causes for oxy fuel multi-flame (rosebud) heating tip
problems or failures like overheating, flashbacks, popping etc.? LACK OF
OXEGEN and reflected heat caueses it to heat up
53. What is the withdrawal rate of an acetylene cylinder? 1/7 per
hour
54. What is the correct process for setting flow when using a heating
tip? maximum flow wide open
55. Is it worth it to pay for welding school?... yes
56. What advice would you follow to become a welder? whatever advice a
certified person told me and if it made sense.
you messed up the
########
59. . Is it a good idea for a welder starting out to get into
an apprenticeship program? (I would google apprenticeship welding)

is the difference between union pay and non union
pay for welders? almost double 15-28
62. Who
makes more money, union welders, or non union
