Deformation control during steel plate welding is an important research field,as heat is generated during the welding process,which leads to deformation of the steel plate and affects welding quality and structural stability.Therefore,studying how to effectively control welding deformation and improve welding quality and structural reliability is of great significance.This paper focuses on the welding deformation problem of low-carbon steel plates and analyzes the effects of factors such as thermal effects,differences in material properties,and external forces on welding deformation.A series of control methods have been proposed to address these issues,including preheating and temperature control,welding parameter adjustment,fixtures and supports,loose constraints,and post-processing.By taking these measures,welding deformation can be effectively controlled,welding quality and workpiece performance can be improved.This study has certain reference value for the optimization and application of welding processes for low-carbon steel plates.
