Welding Path Planning Algorithm for Medium-Thick Plate based on Process Parameters

Most of medium-thick plates are connected by multi-layer and multi pass welding. This paper deals with multi - layer and multi - pass welding of single side V-groove of medium-thick plate. In this paper, the multi-layer and multi-pass welding of medium-thick plate is mainly studied. Firstly, a welding track planning algorithm based on welding parameters is proposed, then the relationship between welding parameters and welding forming coefficient is obtained through experiments on different welding parameters by automatic welding equipment. Finally, the algorithm is verified by automatic welding, after quality inspection, the test plate for welded steel members conforms to the practical engineering standard. The algorithm can guide the welding operation of the automatic welding equipment in the actual construction site.
