Week 3 Verification of Weld Joints

Verification of Weld Joints

AIM:

Case 1. Stainless Steel: In this case, the material of the plates must also be the same. Use Stainless steel for both weldments and plates. No need to add flux to the weldments.

PROCESS:

• Download the model and import into geometry in ansys workbench

• Add the material in Engineering data which is given

• Open geometry and check if any issues

• Update the model and open
• In the geometry select all and in materials selection select stainless steel

• In connection contact kepp it based on defination

• Check got the mesh quality

• In static structure fix the holes of the plate as required

• Put the force on the other location

• In solution add the given Directional Deformation and equivalent strain experienced by the setup

Directional Deformation

equivalent strain

• Highest & lowest stress in model

• Identify the weld joint that experiences the highest equivalent stress

To check value select that weld in stress

Case 2. Aluminium Alloy:The material to be chosen for this case is Aluminium alloy(high strength, wrought). [Plate material to be used is stainless steel]

• FOR OTHER TWO CASES JUST DUPLICATE IT AND ADD THE MATERIAL IN ENGINEERING DATA

• UPDATE THE MODEL & OPEN IT
• IN GEOMETRY SELECT THE MATERIAL AS GIVEN IN CASE TWO CLEAR THE DATA AND ANALYSIS THE SOLUTION

• • In solution add the given Directional Deformation and equivalent strain experienced by the setup

  Directional Deformation

• equivalent strain

• Highest & lowest stress in model

• Identify the weld joint that experiences the highest equivalent stress
• To check value select that weld in stress

Case 3.Bronze: In order to simulate "Brazing", you should be using bronze as the weld material. Assign Stainless Steel to both plates and Copper to the "Ribs".

• FOR OTHER TWO CASES JUST DUPLICATE IT AND ADD THE MATERIAL IN ENGINEERING DATA

• UPDATE THE MODEL & OPEN IT
• IN GEOMETRY SELECT THE MATERIAL AS GIVEN IN CASE TWO CLEAR THE DATA AND ANALYSIS THE SOLUTION
  • In solution add the given Directional Deformation and equivalent strain experienced by the setup

• Directional Deformation

• equivalent strain

• Highest & lowest stress in model

• Identify the weld joint that experiences the highest equivalent stress

• To check value select that weld in stress

compare the results for all three cases

	Directional Deformation	equivalent strain	weld joint that experiences the highest equivalent stress
Case 1. Stainless Steel	0.078836mm	0.0015609	250.86MPa
Case 2. Aluminium Alloy	0.081124mm	0.0018789	138.66MPa
Case 3.Bronze	0.080994mm	0.0017919	143.35MPa

By the observation of all three cases we can say that :

• The Stainless Steel has a Directional Deformation of 0.078836mm which is less than Bronze & Aluminium Alloy
• The equivalent strain has a least value of 0.0015609 which is of stainless steel
• The Aluminium Alloy has weld joint that experiences the lowest equivalent stress as compared to Bronze & Stainless Steel

So, we can conclude that

If you are going with a safety weld with Aluminium Alloy as it has lowest equivalent stress as compared to Bronze & Stainless Steel

If you are going with economy Bronze weld would be prefered and least preference to Stainless Steel as it has weld joint that experiences the highest equivalent stress
