Processes
process involving a rod
Stick or SMAW
(T/F) is welding in a confined space safe?
False no it is very much not safe
melting metal into a coalescence and join 2 pieces of metal to each other
Welding
(T/F) should you leave flammable materials in your welding space
NO absolutely not never do that please
when was welding widely desired
WW1
process involving a continuous wire and shielding gasses
GMAW or MIG
(T/F) Do you need a degree to weld
No you do not surprisingly they only look for experience
using a (blank) flame to make 1 piece of metal into 2
cutting
(T/F) should you touch the metal with your bare hands
False who would willingly touch essentially a hotter oven rack after they made a frozen pizza
when was the true birth of welding
19th century
(T/F) DC stands for Direct Connection
False it stands for Direct Circuit
Welders (blank) to either clean the metal for welding or clean off slag from the weld
Grind with a grinder (slag hammer for half points from the cleaning of the weld)
(T/F) can robot weld?
true they can somewhat not as versatile as humans though
when was the partial birth of welding
18th century
process involving being submerged beneath the surface of water
Underwater welding
(T/F) do we call a weld pool a coalescence
true we do indeed call it that
welding on the x axis
1G or flat
(T/F) welders make over $40k a year on average
true is good money
how were the first rods as we call them today made
metal wire coated with a flux of carbonates and silicates
process involving a tungsten rod for filler material and a continuous arc and gas
TIG or tungsten welding
(T/F) slag is left over carbon that is forced to the surface of the weld from it being lighter than the filler metal
True
welding on the y axis
3G or vertical
(T/F) is it ok to leave your machine on while going to cool your metal in a cauldron of water
trick question it is for cooling purposes but every other time it should be turned off even if only briefly away
where will welding be in 15 or more years
Space most likely
