Mixed production batches
Reconfigure the same platform for changing product sizes, prototypes and recurring medium-volume work.
D22 modular hole system
D22 welding tablesfor mixed fabrication
Ø22 mm holes on a 100 mm grid. General fabrication where one table covers several job sizes.
Why D22
One flexible system for changing job sizes
A middle option between a fine D16 grid and a heavy D28 system. Suits shops that run both small frames and medium structures on the same table.
Choose D22 when the production mix changes frequently and one table must handle light frames one day and medium structures the next. It balances accessory size, working clearance and clamping capacity without moving to the largest tooling system.
- Hole diameter: Ø22 mm
- Standard grid: 100 mm
- Steel or nitrided steel platform options
- Tooling matched to the Ø22 mm bore
D22 project profile
The workpiece and clamping load decide whether this is the right system.
- Typical work
- General fabrication where one table covers several job sizes
- Fixture plan
- General-purpose clamps, medium angle squares, locating stops and pins sized for the 22 mm bore.
- Choose another
- Choose D16 for dense positioning around small components, or D28 when large structures and high clamping loads dominate production.
- Quote input
- Drawing, size, weight, flatness, quantity and destination
Typical D22 work
Where this hole system earns its place
Examples are a selection guide. Final table construction and support are confirmed from the approved workpiece drawing.
Machine guards and frames
Square medium profiles and sheet-metal frames with enough clearance for welding and inspection.
General repair fabrication
Support varied assemblies when the next job cannot be predicted far enough to justify a dedicated jig.
Quote checklist
Configure the D22 3D welding table around the workpiece
This is a made-to-order modular welding fixture table, not one fixed stock model. The approved drawing sets the platform size, working height, surface, accuracy and matched accessory kit.
Use the checklist to give a welding table manufacturer enough information to review the configuration before quoting.
Smallest and largest job
Share both ends of the production range so the D22 system is checked against the work it must cover.
Changeover pattern
Identify recurring datums and batch changes so stops and angle squares can be reused between products.
Platform configuration
Confirm table length, width, working height, flatness grade and whether a nitrided surface is needed.
Matched D22 tooling
Specify the starting mix of clamps, medium angle squares, locating stops and 22 mm pins.
Platform finish
Use the same hole system on either surface
Select the platform construction and treatment from production volume, wear and maintenance requirements.

D16, D22 or D28: pick the grid around the work
The hole system sets how much holding force the table gives you and how fine the positioning is. It is the first decision, because every clamp, pin and stop has to match it.
D16 welding table system
- Hole diameter
- Ø16 mm
- Grid
- 50 mm
- Best for
- Light to medium parts, jigs, frames and detail work
D22 welding table system
- Hole diameter
- Ø22 mm
- Grid
- 100 mm
- Best for
- General fabrication where one table covers several job sizes
D28 welding table system
- Hole diameter
- Ø28 mm
- Grid
- 100 mm
- Best for
- Large fabrications, thick plate and heavy welded structures
What actually changes between the series
Larger holes take larger pins and clamps, so a D28 table holds heavy structures more securely. Smaller holes let you place stops closer together, which helps small parts and tight geometry. The machined grid, hole spacing and flatness are set at the same time, so tell us the workpiece and we will match the system to it.
- Grid spacing confirmed against the drawing
- Plain bore matched to the selected system
- Flatness from 0.1 mm/m² down to 0.02 mm/m²
Questions
D22 welding table questions
If your question is not here, send it over — practical answers are usually faster than a specification sheet.
- When is D22 a better choice than D16 or D28?
- D22 is useful when one table must cover a broad middle range of work. It offers larger tooling than D16 without the weight and space of a D28 accessory set.
- Does the D22 system use a 100 mm hole grid?
- Yes. BECO D22 tables use 22 mm holes on a 100 mm grid unless a different drawing is confirmed as a custom requirement.
- Can a D22 table be supplied with nitriding?
- Yes. The platform can be supplied as machined steel or with plasma nitriding, subject to the confirmed drawing and surface-treatment requirements.
- Will D16 or D28 accessories fit a D22 welding table?
- No. Pins, bolts and clamps must match the 22 mm bore and the confirmed grid. Order D22 tooling with the table, or send the dimensions of existing accessories so compatibility can be checked before quotation.
