Precise Welding Services for Optimal Fabrication

Laser welding and micro-plasma welding represent the most precise welding methods available today. Laser welding delivers exceptional accuracy through highly focused energy beams (0.2-2mm spot size), enabling controlled heat input as low as 0.1mm penetration depth. This minimizes heat-affected zones and distortion, making it ideal for medical devices, aerospace components, and micro-mechanical assemblies. Micro-plasma welding offers similar precision for slightly larger applications. At Wintegral, we utilize both technologies alongside micro-GTAW for applications requiring surgical precision, consistently achieving tolerances that conventional welding cannot match.

A precision welder specializes in joining or repairing components that demand exceptional accuracy, tight tolerances, and controlled heat input. Unlike conventional welding, precision welding focuses on micro-scale work, delicate materials, high-value components, and applications where dimensional stability is critical. Precision welders work with advanced equipment like laser welding systems, micro-plasma units, and micro-TIG setups, often under microscope guidance. They develop custom fixtures, optimize weld parameters, and follow documented procedures to ensure repeatability. At Wintegral, our precision welders handle everything from 50-gram medical components to aerospace assemblies, supporting prototyping, tool repair, and production manufacturing.

Yes, TIG (Tungsten Inert Gas) welding, also known as GTAW (Gas Tungsten Arc Welding), is among the most precise arc welding processes available. TIG welding offers superior control over heat input, penetration depth, and weld pool behavior, making it ideal for thin materials, complex geometries, and applications requiring high weld quality. When executed by certified welders using micro-TIG techniques, it achieves precision suitable for aerospace, medical, and defense applications. At Wintegral, we provide both standard TIG and micro-GTAW services, including NADCAP-certified GTAW for aerospace programs, ensuring precision joining with documented procedures and traceable quality control.

We offer a comprehensive range of precision welding processes: laser welding for ultra-precise, low-heat joining; micro-plasma welding for delicate components; TIG/GTAW welding including NADCAP-certified capabilities; micro-GTAW for thin-section aerospace and medical work; GMAW/MIG for production-scale applications; longitudinal seam GTAW for cylindrical assemblies; and proprietary hybrid laser-micro GT processes. This multi-process capability allows us to select the optimal, most economical method for each application, whether prototype development, tool repair, or production manufacturing.

Absolutely. Our Mould, Tool and Die Repair Division specializes in restoring damaged or worn precision tooling using advanced welding technologies. We repair plastic injection moulds, pressure die-casting dies, compression moulds, rubber moulds, and metal injection moulds of any size or weight. Common repairs include broken cutting edges, damaged pockets, worn surfaces, crashed inserts, and texture restoration. Using laser welding, micro-plasma, and material addition techniques, we restore tools to original tolerances with minimal heat-affected zones, often extending tool life beyond original specifications while delivering dramatic cost savings versus replacement.

We weld a comprehensive range of materials including stainless steel (all grades), aluminum alloys, titanium, carbon steel, tool steels (H-13, H-21, P-20, D2, M2, S7, SS420), copper, beryllium copper, and specialty alloys. Our multi-process capabilities and high-grade welding materials sourced from globally recognized suppliers enable us to handle challenging material combinations, dissimilar metal joining, and applications requiring specific metallurgical properties. Material selection and welding parameters are optimized based on application requirements, ensuring metallurgical integrity and long-term performance.

Yes, R&D and prototype support is a core strength. We function as an engineering partner for product development teams, supporting welding process development, tooling design, weld trials, and validation. This includes building custom fixtures, documenting procedures, iterating designs for manufacturability, and validating weld quality before production scaling. Whether you need 10 prototype assemblies or technical guidance on weldability, we provide flexible support with quick turnaround times. Our R&D partnership service has supported innovation across medical devices, aerospace instrumentation, automotive components, and specialized industrial equipment.

Turnaround times vary based on project complexity, welding process required, and current capacity. For standard tool repairs, typical lead times range from 3-7 business days after evaluation. Prototype welding and small-batch production often complete within 5-10 business days. Urgent or production-critical repairs receive priority scheduling. We communicate realistic delivery timelines upfront after technical analysis, and our multi-city facilities (Bengaluru and Pune) enable us to manage capacity efficiently. For ongoing contract manufacturing relationships, we establish dedicated scheduling aligned with your production needs.
