Describe the weldment and joint variation
Provide drawings, photographs and representative samples when possible. Mark materials, thicknesses, seam locations, joint types, weld sizes, allowable gaps and areas the torch or clamps cannot enter.
- 2D/3D assembly and part drawings
- Material, thickness and surface condition
- Weld map, gap and fit-up range
Define the required weld result
State the current process, filler wire, shielding gas and known parameters, then define visual, dimensional or test acceptance. If a procedure qualification or trial weld is required, make it a formal validation gate.
- MIG/MAG, TIG or other process
- Appearance, penetration and distortion criteria
- Inspection and sample requirements
Add production and handling facts
Share annual volume, batch size, target cycle, model mix and current staffing. Explain how parts arrive, how finished parts leave, whether operators load during welding and which positioner or buffer concept is preferred.
- Cycle and output target
- Loading, unloading and changeover
- Fixture, positioner and buffer
Request one comparable commercial scope
Ask the supplier to identify included robot, source, torch, feeder, fixture, positioner, sensing, safety, fume control, programming, FAT, shipping, installation, training, warranty and spare-parts responsibilities.
- Complete equipment and service BOM
- Included and excluded responsibilities
- Cost drivers, lead time and acceptance plan
Decision checklist
Use the same inputs when comparing supplier proposals.
| Decision area | Inputs to confirm |
|---|---|
| Describe the weldment and joint variation | 2D/3D assembly and part drawings; Material, thickness and surface condition; Weld map, gap and fit-up range |
| Define the required weld result | MIG/MAG, TIG or other process; Appearance, penetration and distortion criteria; Inspection and sample requirements |
| Add production and handling facts | Cycle and output target; Loading, unloading and changeover; Fixture, positioner and buffer |
| Request one comparable commercial scope | Complete equipment and service BOM; Included and excluded responsibilities; Cost drivers, lead time and acceptance plan |
Move from research to a commercial review
Upload the weldment and known process data; missing items can be identified during review.
