For modern shipbuilding industry, welding is a vital key technique, which not only affects the construction quality of ships in large degree, but also plays vital role in improving the production and shortening the shipbuilding period.

Turning plate over is unnecessarily need while using FCB one-sided submerged arc welding, which will help to improve the work flow of ship hull production and increase the production efficiency. However, cracks often occur at some area beside the weld end when using this welding technique, as a result, if no solution is given to solve the problem of cracks occurrence, negative

effects will be upon the regular operation of production line.

Since the welding heat process is of significant effect in controlling the occurrence of cracks beside weld end, and in improving welding quality and production efficiency, therefore, a good master of basic welding rules and variation tendency under various welding condition is of great significance.

In this paper, using the software ANSYS, the welding process of FCB three wires submerged arc welding was successfully simulated, and many heat source models of multiple wire submerged-arc welding were established. In addition, with the application of ansys parameter design language (i.e.APDL language), it realized the algorithm for mobile loading of heat flux and eventually obtained the distribution of welding temperature field of FCB submerged-arc welding, providing basis for the analysis of cracks beside weld end.
