This paper presents a portable robot that is to use for welding process in shipbuilding yard. It has six degree of freedom and 3kg payload capability. Its weight is 21.5kg so that human workers can carry it to the work place. Its body mainly made of magnesium alloy and aluminum alloy for few parts that require high strength. Since the distance between robot and controller should be 50m at most,...

Titanium and its alloys are widely used in aircraft, rocket production, shipbuilding, machine industry, chemical and food industry, medicine due to their high specific strength, good corrosion resistance and biological passivity. However, titanium has properties which limit its application as construction material. Particularly, tendency to surface adhesion and galling at friction results in it...

In this paper some recent advances in lightweight construction for modern shipbuilding are presented. Following a description of lightweight structures and their current use in shipbuilding, emphasis is put on naval applications of composites, and in particular on aspects related to cost benefit assessment and survivability. The following part reports on the use of adhesive bonding for superstr...

Shipbuilding Industry has undergone major changes in the past two decades. Maritime sector has grown rapidly and so has the competition. In order to survive in this competitive environment shipyards have to organize and utilize their resources at optimum capacity and efficiency. Planning and management of resources is a very crucial aspect of shipbuilding industry. There are many constraints on...

Much scholarship has been undertaken with regards to the evolution of the European shipbuilding traditions and their physical changes, but few explanations for the changes are given. This paper seeks to identify the correlations between the expansion of the English timber trade in the fourteenth to seventeenth centuries and the changes in shipbuilding at the time, thereby creating a framework f...

INTRODUCTION Chronic Obstructive Pulmonary Disease (COPD) has a significant impact on quality of life-related health. AIM It was the detection of Chronic Obstructive Pulmonary Disease by using telemetric methods and the investigation of the quality of life for people working in Shipbuilding Industry compared with a control group. METHODS A group of one hundred men working in the shipbuildin...

BACKGROUND Workplace safety regulations seek to mitigate noise-induced hearing loss (NIHL), conventionally associated with the shipbuilding industry. Despite this, are workers still predisposed to NIHL? AIMS To study the prevalence of NIHL among noise-exposed subjects in the shipbuilding industry in Goa and to compare it with that among the non-exposed population working in the same industry ...

Abstract The shipbuilding industry has been drastically affected by demand fluctuations. Currently, it faces intense global competition and a crisis because of an imbalance between supply demand. This is caused excess capacity. Organisation for Economic Co-operation Development considered adjusting the capacity to reduce based on forecast. On other hand, forecast complex issue influenced indire...

The modern stage of shipbuilding industry development is characterized by an intense competition and the beginning introduction new materials effective welding technologies, which change appearance this quite conservative field, at leading global enterprises. In particular, application laser technologies during ship construction decreases cost hull manufacturing 30%, increases production capaci...
