4. Undertaking
I declare that the work presented in this project titled “prepare a model of
types of joint in welded connection . Submitted to the civil engineering
department. Bareilly for the award of “Diploma in Civil Engineering
Department” is my original work. I have not plagiarized or submitted
the same work for the award of any other diploma.
In case this undertaking is found incorrect, I accept that my diploma may
be unconditionally withdrawn.

6. Defination of joint:-
Joint is a separation provided in a building that allows it's
component parts to move with respect to each other; a joint where two placements
of concrete meet. The purpose of a construction joint is to allow for some
horizontal movement, while being rigid against rotational and vertical movement.
Type of lap joint :-
(1)Lap joint
(2)Butt joint
Lap joint-:-Joint is a separation provided in a building that allows it's component
parts to move with respect to each other; a joint where two placements of concrete
meet. The purpose of a construction joint is to allow for some horizontal
movement, while being rigid against rotational and vertical movement.
Welding joints is an edge or point where two or more metal pieces or plastic pieces
are joined together. The two or more workpieces ( either metal or plastic) are
joined with the help of a suitable welding process to form a strong joint. According

7. to the American Welding Society, there are basically five types of welding joints
and these are Butt, Corner, Lap, Tee, and edge joint.
The 5 basic welding joints are
1. Butt joint
2. Corner joint
3. Lap joint
4. Tee joint and
5. Edge joint
types of welding joints
Let’s discuss each one in detail
1. Butt Joint:
The joint which is formed by placing the ends of two parts together is called butt
joint. In butt joint the two parts are lie on the same plane or side by side. It is the
most simplest type of joint used to join metal or plastic parts together.
The different weld types in butt welding are
(i) Square Butt weld
(ii) Bevel groove weld

8. (iii) V-groove weld
(iv) J-groove weld
(v) U-groove weld
(vi) Flare-V-groove weld
(vii) Flare-bevel-groove butt weld

2. Corner Joint
The joint formed by placing the corner of two parts at right angle is called the
corner joint ( see fig above). Two parts which are going to be weld with corner
joint form the shape of L
The different weld types in corner joint are as follows
(i) Fillet weld

9. (ii) Spot weld
(iii) Square-groove weld or butt weld
(iv) V-groove weld
(v) Bevel-groove weld
(vi) U-groove weld
(vii) J-groove weld
(viii) Flare-V-groove weld
(ix) Edge weld
(x) Corner-flange weld
3. T-Joint
The joint which is made by intersecting two parts at right angle (i.e at 90 degree)
and one part lie at the centre of the other. It is called as T joint as the two part
welded look like english letter ‘T’.
The types of welds in T joint are as follows
(i) Fillet weld
(ii) Plug weld

10. (iii) Slot weld
(iv) Bevel-groove weld
(v) J-groove weld
(vi) Flare-bevel groove
(vii) Melt-through weld
4. Lap Joint
The lap joint is formed when the two parts are placed one over another and than
welded ( see fig above). It may one sided or double sided. This types of welding
joints are mostly used to join two pieces with different thickness.

The Various weld types in lap joint are

11. (i) Fillet weld
(ii) Bevel-groove weld
(iii) J-groove weld
(iv) Plug weld
(v) Slot weld
(vi) Spot weld
(vii) Flare-bevel-groove weld
5. Edge Joint
The joint formed by welding the edges of two parts together are called
edge joint. This joint is used where the edges of two sheets are adjacent
and are approximately parallel planes at the point of welding. In this
joint the weld does not penetrates completely the thickness of joint, so it
can not be used in stress and pressure application.
The various weld types in this welding joint are:
(i) Square-groove weld or butt weld
(ii) Bevel-groove weld
