The document presents a presentation on the topic of eccentric load in plane of welds within mechanical engineering. It covers the welding process, various types of welds, and specifically addresses eccentric loads that do not act along the central axis of structural members, distinguishing between those causing twisting and bending moments. The presentation emphasizes the implications of eccentric loading on the integrity of welds.

3.  WELDING PROCESS : -
 Welding is the process of metallurgical joining of metals by
application of heat or pressure or both.
 Welding is one of the most important methods of joining metals.
 Most welds are made at fusion temperature and require the
addition of a filler metal in some form.
 Welding may be manual, semiautomatic or automatic.

4.  TYPES OF WELDS : -
1) Bead weld 2) Groove weld

5. 3) Fillet weld 4) Plug weld

6. 5) Spot weld 6) Seam weld

7.  ECCENTRICALLY LOADED CONNECTION : -
Generally the structural members are subjected to the axial loading
which is acting on the central vertical axis of the member.
But sometimes it is possibility that the load acting on the members is
not particularly on its axis but a far distance from its centre.
That distance is considered as the eccentric distance and the load
acting at that particular distance apart from its axis is defined as
eccentric load.

8.  Types of welding joints subjected to eccentric load :
-
(A) Eccentric load causing twisting moment
(B) Eccentric load causing bending moment

9. (A) eccentric load causing twisting moment
The centre of gravity of the weld lies in the plane of line of action of the
applied load.

10. (B) Eccentric load causing bending moment
The centre of gravity of the weld does not lies in the plane of line of
action of the applied load.
 The load will cause direct shear and bending moment in the weld.
