The invention discloses a welding simulation method and system for achieving welding bead dynamic filling and a storage medium. The method comprises the steps that a simulation model of a welding structure is imported; according to the welding sequence, thermal boundary conditions are loaded on each welding seam in sequence, the filling units of the welding seams which are not welded are hidden, the filling units of the welding seams which are welded are activated, and the dynamic welding seam filling process in the actual welding process is simulated; and outputting welding deformation data of the simulation model. According to the method, the filling units of the weld joints which are not welded are hidden in the welding process, the filling units of the weld joints which are welded are activated, the conformity between the structural rigidity of the simulation model and the actual structure is improved, and therefore the accuracy of the simulation result is improved; the problem that ...

The invention relates to a medium-plate butt seam welding component based on ceramic arc-striking backings. The medium-plate butt seam welding component comprises two ceramic arc-striking backing units with the same structure, wherein the two ceramic arc-striking backing units can be fixed at the two ends of a butt seam; each ceramic arc-striking backing unit comprises a ceramic backing, a conductive lining plate close to the ceramic backing and ceramic blocks, and the ceramic blocks are arranged at the two ends of the butt seam and press the conductive lining plate. The invention further provides a medium-plate butt seam welding method based on the ceramic arc-striking backings. Compared with the prior art, the medium-plate butt seam welding component and the method completely give up steel arc-striking plates used for starting arc, stopping arc and supporting molten bath metal of welding seams when medium plates are welded, eliminate large workload brought by the air gouging operation ...
