Question

Filler metals are tested for mechanical properties that consist of yield strength and Charpy V-notch (toughness). What other 2 properties are they tested for___________.

1) Ductility and Tensile Strength
2) Hardness and Fatigue Strength
3) Corrosion Resistance and Elastic Modulus
4) Thermal Conductivity and Electrical Conductivity

Answer 1

Filler metals are tested for ductility and tensile strength, which measure a metal's ability to deform under stress and withstand stress before breaking, respectively.

Step-by-step explanation:

Filler metals used in welding are tested for various mechanical properties to ensure they are suitable for specific applications. In addition to yield strength and Charpy V-notch toughness, these metals are also tested for two other key properties: ductility and tensile strength.

Ductility is a measure of a material's ability to deform under tensile stress and is important for determining how well a metal can be drawn into wires or other extended shapes. Tensile strength, on the other hand, is a measure of the maximum stress that a material can withstand while being stretched or pulled before failing.
