What type of fusion weld is the most susceptible to mechanical fracture? Why?
Arc welding is more susceptible to mechanical fracture because welding depends on
1) Fusion in the side wall
2) Fusion between material
3) Fusion at the root of the material
When all these factors are considered,In Arc welding there is high chance of fracture when compared to other fusion welds.
There are also certain precautions to be taken while welding to prevent from fracture such as arc length, angle of electrode, and also from overheating which leads to more heat affected zone ultimately result in failure.
What type of fusion weld is the most susceptible to mechanical fracture? Why?
Q1: What is the heat-affected zone (HAZ) in a fusion weld? What are some of the design guidelines for weldments that are fabricated by arc welding? What are several modern-day variations of forge welding? Discuss the reasons why most welding operations are inherently dangerous. Note: Please write in your own words don't copy and paste.
A test of weld strength involves loading welded joints until a fracture occurs. For a certain type of weld, 80% of the fractures occur in the weld itself, while the other 20% occur in the beam. A number of welds are tested and the tests are independent. Let X be the number of test at which the first beam fracture is observed. 5. IIM a) Find P(X23). b) Find E(X and V(x)
