Marine structure welding part

Marine structure welding and painting is the most process in the shipbuilding industry. Welded joints as compared to riveted joints are much easier to produce and they reduce the cycle time of the project. Welded joints have also resulted in reduced steel weight and require less to negligible maintenance compared to rivet joints.

Marine structure welding and painting is the most process in the shipbuilding industry. Welded joints as compared to riveted joints are much easier to produce and they reduce the cycle time of the project. Welded joints have also resulted in reduced steel weight and require less to negligible maintenance compared to rivet joints. 

The three main welding techniques that are used in a shipyard are as follows:

Arc Welding

Gas Welding

Resistance Welding

The most common weld defects are as follows:

1. Lamellar tearing.

2. Crater cracks.

3. Inadequate cross section or insufficient penetration of weld pool.

4. Underbead cutting.

5. Gas entrapment within the weld pool.

6. Slag inclusions within the weld joint.

7. Overlaps.

8. Undercuts.

9. Lack of reinforcement.

10. Excessive reinforcement or extra deposition.

11. Lack of fusion within the weld pool.

Ultrasonic Testing

Weld Defects and Weld Quality Testing is by ultrasonic test, First, use of ultrasonic radiations eradicates the health hazards related to harmful X-Rays and Gamma rays used in radiographic tests. Secondly, the recordings need not be processed as much as that of radiographic tests, because they are obtained in graphical format as discussed below.
