The Industrial Revolution, from 1750 to 1850, introduced a method of joining pieces of iron together known as forced welding.
Hammer welding preceded resistance welding.
Pressure and heat are both necessary to create a weld.
In some instances, pressure alone may sufficient to force separate pieces of material to combine and form one piece.
GTA welding is the cleanest of all the manual welding processes.
Gas metal arc welding and flux cored arc welding are very different welding processes, but they use very similar welding equipment.
The highest paid welders are those who have the education and skills to read blueprints and do the required work to produce a weldment to stick specifications.
Generally seventeen months of training are required to learn to weld.
A formal apprenticeship is usually required to become a general welder.
3/4 inch equals 28 millimeters.
_________ welding was introduced first.
Forged or hammer
Resistance
Fusion
Oxyacetylene
Oxyacetylene welding is also refereed to as _________.
gas welding or torch welding
gas metal arc welding, or just gas welding
gas flux cored arc welding
shielded metal arc welding or torch arc welding
An advantage of ______ welding is that a variety of metal types and metal thicknesses can be joined with one machine.
oxyacetylene
shielded metal arc
gas metal arc
flux cored arc
______ welding can be used to weld metal ranging in thickness from thin-gauge sheet metal to heavy plate by making only a few changes in the welding setup.
Shielded metal arc
Gas metal arc
Flux cored arc
______ welding is extremely fast and economical because it an produce long welds rapidly that require very little post weld cleanup.
SMA
GMA
GTA
GMA and _____ welding are the first choice for many welding fabricators because these processes are cost effective, produce high quality welds and are flexible and versatile.
FCA
OA
______ cutting uses a stiff, highly ionized, extremely hot column of gas to almost instantly vaporize the metal being cut.
Laser beam
Air carbon arc
Oxyfuel arc
Plasma Arc
In selecting the joining process, one consideration relates to the ______, such as whether the parts are made out of a standard metal or an exotic alloy.
quality requirments
appearance of the finished product
materials to be joined
size of the parts to be joined
Welders' helpers ______.

operate machines or automatic equipment used to make welds
often help the welder by making small welds to hold parts in place
design, specify, and oversee the construction of complex weldments
Welding operators _________.
demonstrate good management skill by planning jobs ans assinging workers
Welding shop owners ______.
have a high degree of skill and knowledge of small business management
demonstrate good management skills by planning jobs and assigning workers
Welding shop supervisors _________.
have a high degree of skill an knowledge of small business management
position all the parts in their proper places and make ready for the tack welders
Welding engineers _____.
position all the parts in their proper places and me ready for the tack welders
often help the welder by making small welds to hold part in place
A ________ is required to know all the welding process and metallurgy as well as have good math, reading, communication, and design skills.
welding engineer
welding inspector
weld's helper
welder operator
In many industries, ______ must be able to pass a performance test to specific code or standard.
the welding engineer, the welder, and the welding operator
the welding engineer, the welding inspector, and the welding shop owner
the welder, the welding operator, and the tack welder
the welding operator, the tack welder, and the welder's helper
