This paper presents the results of research on transverse shrinkage of welded butt joints conducted according to the principles of experimental design and under production conditions for two main welding techniques used in shipbuilding (FCAW and SAW). Analysis took into account the technological and structural parameters influencing the assembly suitability of a large steel structure. The presented method of evaluation makes it possible to apply approximation formulae to predict transverse shrinkage in real sections of a ship hull. The determined predictive formulae were verified to actual transverse shrinkage measurements during prefabrication of hull sections at a shipyard as well as the equations referring to the analyzed form of deformation available in the literature.

本文介绍了根据对接设计的实验设计原理和在生产条件下对造船用的两种主要焊接技术（FCAW和SAW）进行的对接焊缝横向收缩的研究结果。分析考虑了影响大型钢结构装配适用性的技术和结构参数。提出的评估方法使得可以应用近似公式来预测船体实际截面中的横向收缩。所确定的预测公式已在船厂预制船体截面的过程中，针对实际的横向收缩率测量结果进行了验证，并验证了参考文献中可用的分析变形形式的方程式。
