Robot Welding Fixture Manufacturers in Chennai

GOALTECH Industries designs and manufactures multi-stage robot welding fixtures in Chennai for automotive body components, structural sub-assemblies, and fabricated sheet metal assemblies. Based at Ambattur Industrial Estate since 2020, we engineer welding fixtures that precisely locate components, clamp them securely, and maintain dimensional stability across thousands of robotic welding cycles.

Our robot welding fixtures are designed from the customer’s 3D component data – ensuring that locating pins, rest pads, and clamping elements are positioned against the correct reference datums from the start. All fixture bodies are CNC-machined for accurate datum surfaces, and locating components are hardened and ground for long production life. We have designed and delivered multi-stage fixtures – covering Stage 1 through Stage 3 welding sequences – for automotive structural applications.

Our Robot Welding Fixture Capabilities

• Multi-stage robot welding fixtures – Stage 1 (tacking), Stage 2 (welding), Stage 3 (finish welding/inspection) in complete fixture sets
• Precision locating using hardened pins, bushes, and machined nest pads – all ground to final dimensional tolerance
• Toggle clamps and pneumatic clamping elements for fast, operator-safe part loading and unloading
• Rigid structural steel fixture frames with CNC-machined datum surfaces – maintaining stability under welding heat
• Robot torch access clearances designed into the fixture layout – avoiding torch collision and spatter accumulation
• Fixture design for MIG welding, TIG welding, and spot welding robotic systems
• Check gauging features integrated into the fixture where dimensional in-process verification is required
• Assembly fixtures combining part positioning and welding for complete sub-assembly operations

Our Fixture Design and Build Process

• 3D component data review – datum scheme definition, part flow analysis, and weld sequence planning
• Fixture CAD design – locating element layout, clamping positions, frame structure, and robot clearance verification
• CNC machining of fixture frame and base on Bridge Type VMC – large assemblies in single setup
• Precision machining of location blocks, rest pads, and nest surfaces on Makino CNC
• Wire Cut EDM for profile-matched location elements and hardened insert profiles
• Grinding of all datum and locating surfaces to final tolerance
• Assembly with hardened pins, bushes, toggle/pneumatic clamps, and reference pads
• Fixture tryout with actual components – positional verification and weld access confirmation before delivery
