Plate connecting method, front floor production method and front floor production line

The invention provides a plate connecting method, a front floor production method and a front floor production line. The plate connecting method are used for a lap joint type fixed connection betweenat least two plates, and comprises the following steps that a lap joint relationship of at least two plates is determined; the material properties of the at least two plates are determined; the beat time required for connection processing of the at least two plates is determined; the connection process is selected according to the lap joint relation and the material attribute, and connection experiments of at least two plates is carried out; when the connection experiment result shows that the connection requirements are met, the connection process of the at least two plates is determined in the beat time. When two or more connecting processes are simultaneously adopted to connect the plates, different processes can be reasonably matched, the maximum safety purpose and economic value are achieved, connection and a
