D16 Modular Welding System Table with 50×50mm Grid Pattern Accuracy
The D16 Modular Welding System Table with 50×50mm Grid Pattern Accuracy is a 5-sided modular welding platform built for precision small-to-medium part fabrication. With tightly controlled grid pattern accuracy, you can build and reconfigure fixtures within minutes for different workpieces, eliminating costly custom jigs.
Once your fixture setup is completed, you can step away for a quick break. When you return, all locating positions stay true with zero drift, and no time-consuming recalibration is required. Featuring plasma-nitrided surface treatment to resist welding spatter and wear from repeated locating-pin operation, this table fits sheet metal work, tube fabrication, prototype development and robotic welding workcells perfectly.

Manufacturing Process
The 50×50 grid hole position accuracy of D16 welding station is ±0.03-0.05mm, which is accumulated by the entire process and cannot be achieved simply by drilling holes.
- Raw material cutting: Q355 high-strength steel plate (optional HT300 cast iron), with a standard plate thickness of 12mm
- Stress relief treatment (key): Overall annealing + artificial aging, some high-end versions do natural aging; Eliminate internal stress in steel plates, avoid warping and deformation of the table surface after long-term welding and heating, and ensure long-term stability of grid accuracy
- Rough milling: Milling flat table top and four side reference surfaces
- CNC five axis machining center: Complete drilling and reaming of the table top and four sides in one go; Drill H7 precision hinge holes with a diameter of 16mm and position them with 50mm grid coordinates to ensure grid pattern accuracy; All holes should be rounded and chamfered to prevent scratches caused by pin insertion and removal
- Shot blasting cleaning: Remove oxide scale
- Plasma gas nitriding: Surface hardening, hardness HV550-800, nitriding layer 0.3-0.5mm; anti welding slag splashing, anti arc burn, wear-resistant, long-term insertion and removal of locating pins are not easy to enlarge holes
- Precision grinding correction flatness: Level 0 accuracy ≤0.05 mm/1000 mm, Level 1 conventional ≤0.1 mm/1000 mm
- Blunt corners and deburring
- Factory full inspection: Flatness, perpendicularity, hole spacing, grid accuracy, hole tolerance, issue inspection report
Attention: The cheap D16 welding table may omit aging and nitriding, and only drill holes. After six months of use, the grid hole position may drift and the positioning may be inaccurate.
Daily Maintenance
- Clean up welding slag splashes after each completion, use a wire brush and oilstone to clean the countertop, and do not use an angle grinder to polish the countertop, as it will damage the nitriding hardened layer
- Regularly apply a small amount of high-temperature grease to the positioning pin and locking bolt to prevent them from getting stuck
- It is strictly prohibited to directly strike the table with an electric arc; It is recommended to spray anti splash agent during welding
- Regularly calibrate the level, ground subsidence will change the welding table level, indirectly affecting grid positioning
- Avoid placing high-temperature workpieces on the table for a long time to prevent local thermal deformation
If the nitriding layer is extensively polished and damaged, the grid accuracy will still be maintained, but the wear resistance of the tabletop will significantly decrease, making it easy to be eroded by welding slag.
Frequently Asked Questions
What is Grid Pattern Accuracy for D16 table?
It is the positional tolerance of 50×50 mm hole-to-hole grid. Our D16 welding table has grid pattern accuracy ±0.03-0.05 mm, to guarantee repeatable locating for modular fixture setup.
Can D16 table be used for heavy structural welding?
D16 welding table is designed for precision small-to-medium parts. For heavy thick-plate structural welding, we recommend D28 system.
Are D16 accessories interchangeable with European brands?
Yes, our D16 hole system is fully compatible with Demmeler & Siegmund D16 modular accessories.
Does the table come with measuring report?
Yes, we can provide measurement protocol including flatness, verticality and grid pattern accuracy for each table.
