[Case Study] Dimensional Discrepancy After Welding
Solve issues such as dimensional changes after welding and parts not fitting together!
At Seiko Industrial, we achieve high precision dimensions through processing design that anticipates deformation caused by welding. We solve issues such as interference during assembly and the need for reprocessing or adjustments. By considering the assembly process, we prevent defects before they occur. 【Customer Challenges and Requests】 ■ Dimensions change after welding ■ Parts do not fit together ■ Interference occurs during assembly ■ Reprocessing or adjustments are necessary ■ Inspection failures occur *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.
