Hole Pattern Welding Grid Table |
Hole Pattern Welding Grid Table refers to a standardized, modular welding workbench. Its surface consists of a precisely machined grid of holes (typically arranged in a regular square or circular pattern), forming a standardized "two-dimensional coordinate system." These holes are used for quickly and accurately mounting various standardized clamps, locating blocks, support pins, and fasteners, thereby creating stable and repeatable welding fixtures in three-dimensional space. It significantly improves the clamping efficiency and positioning accuracy of small-batch, multi-variety welding operations, and is a core piece of equipment for achieving flexible welding manufacturing.

Differentiation from similar products
Compared to T-slot welding tables: Hole-pattern welding tables offer more flexible clamping (360° positioning without blind spots), the holes are less prone to clogging (T-slots easily accumulate welding slag), and maintenance is simpler. The disadvantage is that the heavy-duty clamping force is slightly lower than that of T-slot tables (this can be compensated for with hydraulic clamps).
Compared to ordinary welding plates: Hole-pattern welding tables require no custom tooling, improve clamping efficiency by more than 60%, and offer higher precision. The disadvantage is a slightly higher initial investment, but the overall cost is lower in the long term (over 1 year) due to savings in tooling and labor.
Compared to aluminum profile welding tables: Hole-pattern welding tables have a stronger load-bearing capacity and better wear resistance, making them suitable for metal welding. Aluminum profile tables are only suitable for lightweight non-metallic assembly, so there is no competitive conflict.
Customized solutions
The standard Hole Pattern Welding Grid Table meets 80% of general needs. Customization is key to engaging large clients, and the available customization options are all standard, technically feasible solutions without any technical barriers:
1.Tabletop Customization: Non-standard dimensions (e.g., 1500×2000mm, 2000×3000mm), mixed hole patterns (local 50×50mm precision area + 100×100mm standard area), reserved tooling holes/positioning grooves, tabletop engraving (customer logo/company name)
2.Hole Type Customization: Non-standard hole diameter (e.g., Φ20mm), full threaded hole layout, embedded stainless steel protective sleeves (for wear-prone holes with frequent clamping, extending tabletop lifespan)
3.Structure Customization: Heightened legs (for welding large workpieces), base with drawers/storage compartments, tabletop with T-slots (compatible with T-clamps, expanding clamping options)
4.Function Customization: With slag collection tray + dust removal interface (suitable for European and American customers with high environmental requirements), with hydraulic lifting/rotation (suitable for complex workpieces requiring 360° welding), with anti-static coating (suitable for sheet metal welding of electronic equipment)
5.Accessory Customization: Matching dedicated fixture sets (configured according to customer workpiece type, such as V-blocks + rotating fixtures for pipe welding), customized packaging (export wooden crates/boxes, printed labels/anti-drop markings)
After-sales service plan
Warranty Period: Tiered warranty for core components – Tabletop (S355JR / Ductile Iron): 2-year free warranty (free repair/replacement for deformation, hole wear, and surface layer peeling due to non-human damage); Base/Legs: 1-year free warranty; Clamps/Accessories: 6-month free warranty (free replacement for stripped threads or breakage due to non-human damage).
Warranty Coverage: Excludes human-induced damage (e.g., impact, cutting, overloading), natural wear and tear (e.g., minor wear of holes during normal use), and transportation damage (damage not verified upon receipt).
After-Sales Response: Inquiries will be answered within 24 hours domestically and 48 hours internationally, with remote guidance provided via pictures/videos; for major issues (e.g., severe tabletop deformation), overseas customers can arrange on-site repair by local partner service providers, or receive free replacement parts with shipping costs covered by us (exclusive to large-volume purchasing customers).
Value-Added After-Sales Service: Lifetime free technical consultation (e.g., clamp matching, workpiece clamping solutions); after the warranty period, parts/tabletop repair services will be provided at cost price, without charging for labor or technical fees.
Documentation Support: The shipment includes bilingual (Chinese and English) instruction manuals, installation video QR codes, and clamp usage tutorials. Overseas customers can scan the QR codes at any time without needing to request them separately.
Acceptance criteria and testing methods
1. Core Acceptance Criteria (Consistent with Contract/Quotation)
Tabletop dimensional tolerance: ±1mm (length/width), ±0.5mm (thickness)
Flatness: Standard type ≤0.2mm/m², Precision type ≤0.1mm/m²
Hole spacing tolerance: ≤±0.05mm (precision type), ≤±0.1mm (standard type)
Surface treatment: No paint peeling, no nitride layer detachment, smooth hole walls without burrs or deformation
Accessories: Clamps/bolts are rust-free and without stripped threads, adjustable feet move smoothly
2. Simple Testing Methods (Basic tools provided by the customer are sufficient)
Flatness: Use a spirit level on different positions of the tabletop; the bubble being centered indicates compliance. For high-precision requirements, a dial indicator + magnetic base can be used to test along the X/Y axes; the value fluctuation should be within the tolerance.
Hole spacing/diameter: Randomly test more than 10 hole positions using a vernier caliper/micrometer, take the average value; no significant deviation indicates compliance.
Surface hardness: A hardness test report will be provided (included with the shipment); customers do not need to perform their own testing. The report includes the test results.
