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.

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. |
