What types of design features favor manufacture as a joined assembly? correct answers Large
size products, products with high degree of shape complexity, or products with a wide variation
in required properties
What is welding? correct answers The permanent joining of two base materials using heat and
pressure
What conditions are required to produce an ideal metallurging bond? correct answers Base
metals identical, exact amount of heat and pressure
What are some of the ways in which welding processes compensate for in the inability to meet
the conditions of an ideal bond? correct answers Clean surface, pick a different type of metal for
the filler, pre and post heat the materials as well as understand physics and chemistry
What are some possible problems associated with the high temps that are commonly used in
welding? correct answers You need a heat source higher than the melting temp of the alloy but
after too much heat you can develop cracks, cavities, incomplete fusion, incomplete penetration,
unacceptable shapes, splatter, and undesirable metallurgic changes
What the three primary aspects required to produce a high quality weld? correct answers Heat
pressure and protection
How are welding processes identified by the American welding society? correct answers Flame,
arc, resistance, solid-state, unique
In what way is the weld-pool segment of a fusion weld like a small metal casting? correct
answers You take a solid you add heat put it into a cavity and let it harden
Why is it possible for the fusion zone to have a chemistry that is different from the filler metal?
correct answers If you use too high of a heat you will offset the decridation of the base material
with the filler material
Why is it uncommon for the selected filler metal to have a chemical composition that is different
from the metal being welded? correct answers If you use too high of a heat you will offset the
decridation of the base material with the filler material
What are some of the defects or problems that can occur in the molten metal region of a fusion
weld correct answers Cracks, shrinkage, oxidizes quickly and can develop a hole
Why can then resulting material properties vary widely within welding heat affected zones?
correct answers Temperature and duration widely within location
