WELDING PROCEDURES AND WELDERS — GUIDELINES ON APPROVAL TESTING

This is a compact but very informative and useful booklet providing a summary of the main aspects related to the welding certification. It will be useful to the people willing to get the basic knowledge of the subject without going to deep into the theory and relevant procedures. We have been approving the welding procedures through testing and certifying the welders for more than fifty years.

According to the established practice which shall be strictly followed, the testing shall be done prior to commencement of the production and is therefore considered a QA, i.e. Quality Assurance, rather than just a QC, i.e. Quality Control, measure. The material in this booklet is arranged in section sections. The first section is purely introductory while the remaining sections are dealing with the welding certification itself, welding the specimen, testing and certification, and also some info about SAFed.

There are also several appendixes to the main part of the document – here you will find the information about the test certificates including some samples to be used. Though the publication was not developed specifically for the shipbuilding industry, the content will be useful to all people involved in ship building and ship repair.

THE WELDING OF ALUMINIUM AND ITS ALLOYS

The content of the present publication was specifically developed to assist people working with the aluminium as well as various aluminium alloys. As you know, subject material is in quite wide use in the contemporary shipbuilding. Since connection of different parts of the ship’s hull normally implies their welding one to another, it is very important for the workers and designers to have a good understanding of the welding process.

This is also important because having a good technical knowledge on this would help in evaluation of the weld design at earlier stages, predicting all possible problems in the future. The content of the book will provide all of them with the basic information relating to the metallurgic principles, which they well have to be aware of in order to do a good and defect-less job.

The volume shall be used as a comprehensive guidebook to all shop-floor engineers since the author has covered all important areas including weldability of the aluminium alloys, advantages and disadvantages of application of the different processes, quality assurance and control, solving of the different problems involved, and many other aspects deserving attention.

HOW SHIPS ARE MADE

If you happen to visit any of the great marine ports of the world, for example Sydney or Singapore, or San Francisco, you will surely get be surprised by the huge number of ships of different types and sizes. They are moored alongside, anchored in the vicinity or just passing by through the bay leading to the open sea.

They will include oil and product tankers, passenger liners and dry cargo ships, container carriers and ferries, fishing boats and yachts, and so many others. You will count hundreds of ships since the demands of the modern trade are remarkably diverse nowadays.

This book was written for the newcomers to shipping industry willing to get a general understanding of the shipbuilding process. The way material is presented makes it easy reading even for the people with little to no technical knowledge available. The author starts the book with the explanation of the differences between ship types and some brief information about the ship design and construction process, with particular attention paid to the so-called CAD, standing for the computer assisted design.

The shipbuilding process is explained at every stage, from steel preparation to the launching of the ready ship and put fitting. The sea trials normally conducted upon completion of the ship construction, have been addressed in a separate chapter. The book features a glossary of terminology and is full of brilliant pictures.

THE AUTOMATION AND INTEGRATION OF PRODUCTION PROCESSES IN SHIPBUILDING

The maritime shipping industry has always been of critical importance for the whole Europe, and it still is considered strategically vital to the European economy, as well as the tradition and topology, and of course tradition. Throughout the history, the shipbuilding has been treated as a significant source of employment for the people. Nowadays, shipbuilding together with the related areas, need to go through the serious changes, in order to remain competitive.

The subject changes would include, first of all, the reduction of the lead times, commonly caused by the production over-capacity and competition. It would also be necessary to achieve sustainability throughout the entire process of ship construction. In addition, the highest standards of quality shall be complied with to provide safety and environmental friendliness of the maritime navigation.

All above goals are difficult but possible to achieve but will definitely require improvements in the design and construction of the merchant fleet, as well as its subsequent technical maintenance. The newly introduced technological advances, applied to the shipbuilding industry through, for instance, the laser welding of the ship’s hull, the growing level of automation of all processes, when used properly, will eventually result in the better productivity.
