System 16 Welding Tables for modular fixturing for metal fabrication

System 16 Welding Tables are designed for modular fixturing in metal fabrication, utilizing a standardized 16mm hole diameter and 50mm grid system (metric). They support the quick assembly of functional modules such as positioning blocks, right-angle blocks, and V-blocks, enabling rapid positioning, clamping, and repeatable fixturing of workpieces. They are suitable for metal welding and assembly needs ranging from delicate small parts to medium-duty applications, differentiating them from the System 28 series (28mm hole diameter, 100mm grid) which is designed for heavy-duty fixturing scenarios.

Production process

Steel Smelting and Rolling: The core work surface is made of X8.7 tool steel / S355J2+N structural steel.  Sulfur and phosphorus impurity content is strictly controlled during smelting (P≤0.035%, S≤0.035%). A combined hot rolling and cold rolling process is used during rolling to ensure a uniform metallographic structure within the steel plate and prevent internal stress cracking under high welding temperatures.

Overall Heat Treatment: The work surface undergoes overall quenching + low-temperature tempering treatment, followed by plasma nitriding surface modification. The nitriding layer depth reaches 0.15-0.3mm, which not only improves surface hardness but also provides the work surface with thermal deformation resistance—local high temperatures (≤800℃) transmitted by the workpiece during welding will not cause the work surface to warp, and it quickly recovers its baseline accuracy after cooling.

BAR Coating Process: After nitriding, a proprietary BAR anti-stick coating is applied. The coating thickness is only 0.01mm, which does not affect positioning accuracy. Its core function is to prevent welding slag adhesion, resist coolant/rust inhibitor corrosion, and reduce the friction coefficient between the workpiece and the work surface, preventing scratching of the workpiece surface during clamping.

Precision Machining and Inspection: Five-sided machining (top surface + 4 sides) is performed using a CNC gantry milling machine in a single setup, ensuring flatness and perpendicularity tolerances of ≤0.02mm/m for each surface. Before shipment, a full-size inspection is performed using a coordinate measuring machine (CMM), with a positional tolerance of ≤±0.01mm for the grid holes, ensuring the interchangeability of fixtures.

Routine maintenance and upkeep

System 16's wear-resistant and corrosion-resistant design significantly reduces maintenance costs.  Routine maintenance is simple, ensuring long-term high-precision use. Key maintenance points:

1. Weld Spatter Cleaning: After welding, promptly clean weld spatter from the table surface using a stainless steel scraper/nylon brush. Due to the non-stick properties of the BAR coating, weld spatter does not adhere firmly, eliminating the need for grinding tools such as angle grinders, thus preventing scratches to the table coating and precision surface.
2. Rust Prevention: If the system is not used for an extended period (more than 7 days), apply a thin layer of anti-rust oil/wax to the table surface to prevent oxidation in humid environments; before use, simply wipe with a lint-free cloth dampened with industrial alcohol, which will not affect fixture positioning.
3. Fixture and Hole Maintenance: The grid holes are equipped with replaceable nylon protective sleeves to prevent T-bolts and pins from scratching the hole walls during clamping; regularly check for metal shavings in the holes and clean with compressed air (0.4-0.6MPa), without disassembly.
4. Accuracy Re-inspection: Under normal use, re-inspect the table flatness every 6-12 months using a level/dial indicator. If slight deviations occur due to improper use, they can be recalibrated using the adjustable support feet; in the rare event of severe deformation, the brand provides professional factory repair services.
5. Replacement of Consumable Parts: Support feet, nylon protective sleeves, and connecting pins are standard consumable parts, and universal replacement parts are available for direct purchase and replacement, eliminating the need to replace the entire table.
