A Associação Brasileira de Soldagem (ABS) e a Associação Brasileira de Engenharia e Ciências Mecânicas
(ABCM), através do IV Congresso Brasileiro de Engenharia de Fabricação (COBEF), com o apoio da PUC-Rio
e TWI-Brasil, têm o prazer de convidá-los para a seguinte palestra a ser proferida pelo Prof. Bill Lucas, do
The Welding Institute da Inglaterra
State of the Art’ Review of Underwater Wet Welding
Resumo:
In the offshore industry sector, underwater repairs or strengthening of structures are carried out using mechanical
clamps or hyperbaric welding which employs a local habitat to permit dry welding. Both techniques are very expensive
in terms of deployment and effecting the repairs. The repair of damage to a ship, or the replacement a corroded
section of the structure, will necessitate for dry docking to enable welding to be carried out in air using conventional,
approved consumables. As both methods of repair are extremely expensive, there has been renewed interest in
underwater wet welding as an alternative technique. This will substantially reduce not only the cost. Although wet
welding is widely used for temporary repairs, there are concerns about the quality of the welds especially if permanent
repair are required.
The purpose of this presentation is to review the ‘State of the Art’ of underwater wet welding for carrying underwater
repairs. In reviewing recent advances in underwater welding technology, consideration has been given to:
•
Developments in consumables
•
Developments in welding equipment
•
Quality levels for approved wet procedures
•
Applications
•
Inspection
The advances will be reviewed in terms of their relevance for carrying out wet welding repairs to offshore structures
and marine applications, including the repair of ship structures. Recommendations will also be made on the suitability
of underwater wet welding for effecting permanent repairs of structures.

Prof Bill Lucas is Technology Manager in the Arc, Laser & Sheet Processes Department at TWI. He received his
doctorate from Queen'
s University of Belfast. He was initially employed by Leyland Motors for four years. He joined
TWI in 1970. After 16 years in process research, he became Head of the Arc Welding Department in 1986. In 1987,
he became the first research engineer at TWI to be awarded Doctor of Science for his contribution to arc welding and
computer technology. He has been Visiting Professor at the University of Liverpool since 1997. His research work has
been largely devoted to process development and application studies in welding and cutting and production of
modelling, expert systems and multimedia packages. Over 100 of his papers have been published. He has been
responsible for several National and European projects. He was awarded the Sir William Larke medal in 1984 and
2002 and the IIW Eugenij Paton medal for his contribution to science and technology in 2003. He became a Fellow of
the Welding Institute and of the Institute of Metals in 1983, and a Chartered Engineer and a European Welding
Engineer in 1993.
