What are the three categories of weld discontinuities?
Defective properties, physical discontinuities, mechanical properties.
Structural discontinuities, geometric discontinuities, defective properties.
Geometric discontinuities, defective properties, chemical properties.
Physical discontinuities, chemical properties, mechanical discontinuities. - 🧠
ANSWER ✔✔Structural discontinuities, geometric discontinuities, defective
properties.
All discontinuities are defects.
True.
,False. - 🧠 ANSWER ✔✔false
Defective properties relate to issues with - 🧠 ANSWER ✔✔with the mechanical or
chemical properties of the parent material and/or the filler material.
An incorrect welding procedure can lead to a metallurgical condition known as - 🧠
ANSWER ✔✔Intergranular carbide precipitation. This leads to a loss of corrosion
resistance in the area adjacent to the weld.
When stainless steel is welded by using carbon steel electrodes, too much dilution
in the weldment is the most common reason for the loss of corrosion resistance.
True.
False. - 🧠 ANSWER ✔✔TRUE
What is the most likely cause for property deficiencies in a weldment? select all
that apply.
Contaminated or wet electrodes.
An incorrect welding procedure.
Spatter on the base metal. - 🧠 ANSWER ✔✔Contaminated or wet electrodes.
, 3
An incorrect welding procedure.
Which internal condition is linked with the property deficiencies in a base metal?
Faulty electrodes.
Laminations and stringers.
Surface mill scale or paint.
Spatter on the base metal. - 🧠 ANSWER ✔✔Laminations and stringers.
Geometric discontinuities also called __________________________ can occur
before or after welding. - 🧠 ANSWER ✔✔dimensional discontinuities
Aligned porosity is defined as: (Multiple choice)
Question 1 options:A) porosity aligned in cluster formations.B) porosity which can
behave like a crack.C) porosity oriented in a relatively scattered pattern.D) porosity
lengths perpendicular to the weld face. - 🧠 ANSWER ✔✔B) porosity which can
behave like a crack.
Surface contaminants such as oil, paint, rust, and mill scale can cause overlap.
(True/False) - 🧠 ANSWER ✔✔true
Which type of discontinuity is best described as a weld deposit not melting into a
base or filler material? (Multiple choice)
