[Case Study] Distortion in Welding of Thin Stainless Steel
Solving issues such as lack of dimensional accuracy, bending, and warping!
At Seiko Industrial, we provide processing that suppresses distortion, which is a problem in the welding of thin stainless steel, while achieving both dimensional accuracy and appearance quality. Our customers have faced challenges such as interference and gaps during assembly, as well as the time and effort required for correction work. By comprehensively optimizing welding conditions, jigs, and process design, we contribute to stable quality and reduced downstream processes. 【Customer Challenges and Requests (Partial)】 ■ Dimensional accuracy is not achieved due to welding distortion ■ Bending, warping, and twisting occur ■ Interference and gaps arise during assembly ■ Correction work requires time and effort ■ Quality variation occurs due to correction *For more details, please download the PDF or feel free to contact us.

Our company primarily focuses on welding processing of stainless steel sheets ranging from 0.3mm to 1.5mm, making it the core of our technology, and we have been dedicated to producing products that require precision and quality. We particularly excel in TIG welding of thin stainless steel and are optimizing both welding conditions and process design to address challenges such as distortion due to heat, melting, and appearance defects. In thin sheet welding, fine adjustments to conditions based on material properties, shapes, and required functions significantly influence quality. We conduct welding management that emphasizes the melting state and bead shape, achieving a balance between appearance quality and functional quality. We also ensure stable quality for areas requiring airtightness and durability. Additionally, we provide proposals from a manufacturing perspective that considers weldability from the design stage, suggesting optimal structures that take into account not only quality but also processability and reproducibility. We consistently support our customers' product development and manufacturing as a partner focused on solving technical challenges, from prototyping to mass production.
