This paper regards research as the welding steel welding deformation control and correction of the thesis, mainly focusing on the welding process, the tracking and analysis of welded I-steel welding process and deformation process, make appropriate preventive and corrective methods, try to prevent deformation, deformation control.

In this paper a grey‐box model for the lateral dynamics of an endless steel process belt is presented. Due to their high elastic modulus steel belts are operated on cylindrical return drums which do not provide for passive lateral positioning. Therefore, active control inputs like swiveling of the return drums have to be employed. The model is of sixth order, has a linear state space structure, and is computationally inexpensive. Inputs are the horizontal swivel angles of the drums, a lateral disturbance force and a disturbance moment, outputs are the lateral positions at the return drums. It is convenient for both off‐line and on‐line simulations and perfectly suited for control design. The model is parameterized by a few simple geometric dimensions, the elastic modulus of the strip material, and an adjustable transport delay. Validation results from a scaled experimental belt machine prove the excellent accuracy of the new model.
