Tack Welding Fixtures

Scope and process

Engineering workflow for tack welding fixtures at Dahegam, Gandhinagar, Gujarat, India: 3D CAD modeling of part workholding envelope → FEA clamping force and deflection analysis → CNC machining of hardened baseplates and locator nests → grinding of locating dowels and wear pads → laser CMM verification of critical datum points.

Materials we work with

Heavier section than a machining fixture to absorb heat and resist warp; spatter-resistant clamp faces. Body material is chosen for the duty — tool steel where wear or heat is the issue, aluminium where the fixture must be lifted by hand.

Tooling support

Locates each component to the weld datums and clamps close to the joint.

Choosing the right option

When requesting a proposal for tack welding fixtures, please provide component 3D CAD models (STEP/IGES), 2D part drawings indicating critical datums, machine table specifications (T-slot pitch, pallet size), and target cycle time. Quotes with 3D concept layouts are issued within 24 hours.

Quality checks and inspection

On a fixture the check that matters is dimensional check of a welded sample against the assembly drawing, and fixture recheck after thermal cycling. Dimensions are verified on CMM against the fixture drawing before despatch.

Commissioning and handover

Handed over after a welded sample is measured against the assembly drawing, since distortion only shows in a welded part.

Export packing and lead time

Ships with clamp positions set and marked so the datum scheme can be re-established after transport. HEMSUN is a DGFT IEC registered exporter (Government of India); commercial invoice, packing list and certificate of origin accompany international despatch.

Maintenance and spare parts

Clamp faces and locating pins take spatter and impact; inspect and re-shim on a planned interval.
