High-precision welding for thin plates of 0.3~1.5mm! From design to sheet metal processing, automated welding, and rigorous inspection, we achieve highly reliable components through our integrated in-house production system!
"If you are having trouble with stainless steel welding, leave it to us." Seiwa Industrial Co., Ltd. specializes in welding technology for thin stainless steel sheets and possesses various processing techniques and advanced expertise as a welding and joining specialist. With high technical skills and abundant know-how, we have established advanced welding processes from sheet metal processing to final assembly, backed by years of proven experience. In particular, our welding processing for storage tanks is widely used in domestic electric water heaters and heat pump water heaters by ensuring corrosion resistance and the strength of welded joints. Our technical capabilities range from TIG welding of 0.3mm thickness to fiber laser welding for ultra-thin shapes requiring thicknesses below 0.1mm. We utilize various welding methods such as TIG, fiber laser, and robotic welding, tailored to the structure and material properties of the products. Additionally, to achieve both quality and high productivity, we actively utilize dedicated jigs and automation equipment designed and manufactured by our own production technology department.

Company information
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.
