Structural Subassemblies
Welded plate, tube and formed-sheet structures linking robot equipment, frames and platform mounting interfaces.
Multi-part welded robot modules combining formed sheet, plate, tube, machined pads and drawing-defined hardware. Fixtures and inspection follow cross-part datums so the completed assembly fits the OEM's released robot platform.
A robotic welded OEM assembly connects several fabricated components through one functional datum scheme. Joint sequence, distortion, machined interfaces, installed hardware and final module geometry therefore need to be managed together.
Welded plate, tube and formed-sheet structures linking robot equipment, frames and platform mounting interfaces.
Multi-part motor, gearbox and actuator modules with controlled pilots, pads, axes and cross-member relationships.
Welded supports, trays, rails and hardware supplied as ready-to-install mechanical modules or platform kits.
Fabricated structures combining mounts, guards, access features and shared datums for sensing or protected motion zones.
The robotics OEM or integrator owns system loads, dynamics, controls, guarding, motion safety and final machine validation. DRAmetal manufactures the released assembly to the agreed material, weld, datum, finish, hardware and inspection requirements.
Each family is planned around the completed assembly rather than checking individual cut and formed parts in isolation.
Structural Multi-part steel or stainless weldments joining plate, tube, formed panels and gussets across shared robot-platform datums.
Motion Welded motor and actuator structures with machined pads, locating features and inspection of the completed interface relationship.
Modules Welded trays, support frames, rails and installed hardware organized as one serviceable robot mechanical module.
Protection Multi-part welded supports and guards preserving sensor mounts, service access and protected clearances on a robot platform.

Confirm the BOM, models, drawings, mating envelopes, CTQs, finishes, hardware and released supply boundary.
Connect the important interfaces across individual components and identify the relationships that must survive welding.
Define locators, clamps, tack order, weld access, heat sequence, machining stock and inspection checkpoints.
Build the module through released subassembly stages while monitoring fit-up and distortion before access closes.
Check machined pads, hole patterns, axes, clearances, hardware and cross-part datums in the final supply condition.
Tie the assembly, installed hardware, loose kit items, inspection evidence and packout to the correct robot revision.
Accurate individual parts do not guarantee an accurate welded module. Assembly quality depends on how multiple joints, datums, machined interfaces and hardware interact after the final weld and finish.
A mounting pad on one component may need to align with a hole pattern or sensor face on another component.
Heat from several joints can shift the complete structure even when each local weld appears acceptable.
Pads and pilots may require planned stock, post-weld machining and inspection relative to the full assembly.
Similar modules can contain different brackets, fasteners or orientations that need controlled BOM and packout identity.

Read the Customer Project →Cutting, forming, welding, machining, finish, hardware and inspection are managed around the final module.
Fixtures locate the shared robot datums and preserve access for welding, checks and downstream assembly.
Fabricated structures can incorporate drawing-defined pilots, pads, bosses and post-weld machined faces.
Completed weldments can be delivered with installed hardware, loose kits and revision-specific packout.
The bracket page covers individual localized welded brackets. This assembly scope covers multi-part robot modules with cross-part datums, staged fixtures, machined pads, installed hardware and complete-assembly or kit delivery.
Released assemblies can combine formed sheet, plate, tube, gussets, machined pads, bosses, guards, inserts, fasteners and other drawing-defined mechanical components.
Yes. Where the released design requires it, machining stock and datum pickups can be planned so pads, pilots or faces are machined and inspected relative to the completed weldment.
Yes. Drawing-defined hardware can be installed, and approved loose components can be packed as a revision-controlled module kit with inspection and identity records.
