Abstract With the development of shipbuilding industry, the degree of automation increasingly in improving, ship welding technology has been able to achieve a considerable degree of automation。 Greatly reduced in shipbuilding when the amount of labor, save the shipbuilding cost, improve efficiency。 Ship manufacturing automation not only includes the automation of ship hull manufacturing and other major processes, also contains the ship welding, component transport auxiliary processes automation。 Welding in ship manufacturing cost and man  hour accounted for 30% to 50%, so welding automation is is one of the most important ways that to improve the production efficiency of shipbuilding。

This paper is mainly R & D a automation system which in the welding of thick steel plate heat treatment。 First of all, the article of ship welding automation development situation are introduced。 On the basis of several heat treatment automation system , according to the heat treatment device need work requirements analysis, overall design, and according to the system of analog and switch quantity variables selected the suitable hardware equipment。 Also according to the overall plan, choose the configuration software as the host computer control software, followed  by a detailed software design。 Including the design of flow chart, scripting, interface design, software testing, and so on。 In the last part of the The installation and debugging of hardware and software in the laboratory。 Through laboratory  testing, field installation and debugging, testing results show that the system  can reach  of thick steel plate welding heat treatment process automation control, and achieved the expected results。

Keywords: Ship welding; automatic; heat treatment, configuration software
