This document summarizes information about welded joints. It discusses that welding is a process of joining similar metals by heating with or without applying pressure and filler material. Some advantages of welded joints are that they provide maximum efficiency, can join circular members, and take less time than riveted joints. Types of welded joints discussed include lap/fillet joints, butt joints, and their variations such as single transverse, double transverse, and parallel fillet joints. The document also provides a diagram explaining how to calculate the strength of a transverse fillet welded joint.

Seminar On :- WELDED JOINT
Presented By:- GHEGAD K.T.
Guidance by:- Mr. PAWAR Sir

2.  Welded Joint:- Welding is process of joining two
similar metal by heating with or without application of
pressure and filler material.
Advantages:-
1) Weld joint provide maximum efficiency which is not possible by riveted
joint.
2) Circular shape member are difficult to rivet but they can easily welded.
3) Welding required less time than the riveting.
Disadvantages:-
1) Highly skilled labour and Supervision is required.
2) The inspection of weld is difficult than riveting joint.

3. Types of Welded Joints:
a. Lap joint or fillet joints
b. Butt joint
(a) Types of fillet joint:
1)Single transverse 2) Double transverse

4. 3) Parallel fillet:
The lap joint or fillet joint is obtaineb by overlapping the
weld. The cross section of the fillet is approximately triangular.

5. (b) Butt Joint:- The butt joint is obtained by placing the plate edge to edge.
Type of butt joint :
Symbol:
The other type of welded joints are corner joints, edge joint and T-joint.

6. Strength of Transverse Fillet Welded Joint:-
• Consider a single transverse fillet weld.
∆ABC is a right angle isosceles triangle
Let, t=BD=Throat thick. In mm
Sw=AB=BC=size of weld
Lw=Length of weld in mm
<BAC=<BCA=45⁰
