DNV GL’s Maritime Academy Hellas is offering on 25-26 May 2016, a two-day course (09:30 – 17:00) on Welding. International standards as well as shipbuilding rules, for e.g. steel structures, pressure vessels, pipes and pressure equipment, require qualified welding procedure specifications (WPS) in advance of the production of such welded structures.

The main focus of this course is how to prepare a WPS and it is aimed at all supervisory staff involved in welding.

Preparing a WPS is not as complicated as it seems. The course will demonstrate how welding coordinators can easily and effectively fulfil the requirements of international standards and shipbuilding rules.

Participants in this course will learn how to fill in a template for a WPS properly. If this template is used any WPS developed in future by the course participants will be accepted by third party organisations and customers without complaints.

After a theoretical introduction of each standard the course participants will make practical use of them during the course. They will make their own preheating calculations based on “real life” examples. Welding consumables for specific welding jobs will be chosen from manufacturer’s handbooks. Participants will develop their own WPS which they can discuss with the trainers and learn about the subsequent mechanical and non-destructive tests.

Objective: Participants will be able to correctly develop a WPS and be prepared for the subsequent welding procedure qualification test.

Emphasis will be given on:

§ Welding Processes including numbering system according to ISO 4063
§ Grouping System for Materials according to ISO/TR 15608
§ Welding Positions according to ISO 6947
§ Weld Preparation according to ISO 9692
§ Hydrogen-induced cracking of steel welded joints
§ Choosing the correct welding consumable
§ Determination of Preheating and Interpass Temperature
§ Heat Input Calculation
§ Non Destructive and Mechanical Tests
§ Drafting a WPS according to ISO 15609
§ Qualifying a WPS according to ISO 15614
