Verification of Weld Joints using ANSYS WorkBench

Simulate three different types of welding using three different weld materials

Meshing :-

Mesh Size :- for Plates 6mm & for Ribs and Weldments 4mm

Mesh Type :- Tetrahedron

Weld Material used :-

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.

Weld Material : Stainless Steel (for Plates, Ribs, Weldments)

(a) Equivalent Stress : Max. = 363.59 MPa & Min. = 0.1159 MPa

(b) Equivalent Strain : Max. = 0.0010513 & Min. = 2.2084e-6

(c) Equivalent Stress (on Weldments) : Max. = 363.59 MPa & Min. = 2.147 MPa

(d) Directional Deformation (y-axis) : Max. = 0.31384 & Min. = -0.036502

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]

(a) Equivalent Stress : Max. = 355.01 MPa & Min. = 0.10399 MPa

(b) Equivalent Strain : Max. = 0.0011549 & Min. = 1.6481e-6

(c) Equivalent Stress (on Weldments) : Max. = 311.84 MPa & Min. = 2.4683 MPa

(d) Directional Deformation (y-axis) : Max. = 0.33366 & Min. = -0.036272

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\".

(a) Equivalent Stress : Max. = 361.94 MPa & Min. = 0.12997 MPa

(b) Equivalent Strain : Max. = 0.0013306 & Min. = 3.4542e-6

(c) Equivalent Stress (on Weldments) : Max. = 319.42 MPa & Min. = 1.4178 MPa

(d) Directional Deformation (y-axis) : Max. = 0.36184 & Min. = -0.034171

Result :-

Sr. No.	CASE	Equivalent Stress (MPa)	Equivalent Strain	Equivalent Stress (on Weldment) (MPa)	Directional Deformation Y-axis (mm)
1	CASE 1	Max. = 363.59	Max. = 0.0010513	Max.= 363.59	Max.= 0.31384
Min. = 0.1159	Min. = 2.2084e-6	Min. = 2.147	Min.=-0.036502
2	CASE 2	Max. = 355.01	Max. = 0.0011549	Max. = 311.84	Max.= 0.33366
Min. = 0.10399	Min. = 1.6481e-6	Min. = 2.4683	Min.= -0.036272
3	CASE 3	Max. = 361.94	Max. = 0.0013306	Max. = 319.42	Max.= 0.36184
Min. = 0.12997	Min. = 3.4542e-6	Min. = 1.4178	Min.=-0.034171

(a) Equivalent Stress (MPa) :- Case 1 > Case 3 > Case 2

(b) Equivalent Strain :- Case 3 > Case 2 > Case 1

(c) Equivalent Stress (Weldment) :- Case 1 > Case 3 > Case 2

(d) Directional Deformation :- Case 3 > Case 2 > Case 1

Equivalent Stress & Equivalent Stress (Weldment) is more in case 1 lower in case 2, So better to go with case 2.
