Test4 distortion
Temperature expressed in F OR C
refers to the measure of the, intensity of energy
The term heast
expresses, quantity
Transitional expansion
occurs when metal changes from, one crystalline structure to another
Which type of distortion results from shrinkage across the weld that tends to pull a member of a tee joint toward the welded side
angular distortion
Which type of distortion results in an overall reduction in the length of the weld
longitudinal distortion
Which type of distortion refers to tendency in(butt joints) for the plates to draw together down the length of the joint as your welding
transverse distortion
What causes angular distortion in a vee groove weld if the plates are free to move
the non-uniform contraction of the weld metal
What is the primary cause of distortion created from longitudinal shrinkage
weld beads contracting upon cooling
What welding variable is more likely to have the plates of a butt joint drawn together causing transverse shrinkage
welding at a slower rate
What is one method to reduce transverse distortion
use a fast deposition rate
What is the purpose of balancing welds around the neutral axis of a worn shaft
to equalize contraction stresses of the weld
How can you help distortion on light gauge metal
more tacks
What is one characteristic of a good weld design
it uses formed or rolled sections
What is the advantage of using sub-assemblies
they provide more welds in flat position
