Products Description
High-hardness 3D welding table is professional basic equipment used in the welding industry for workpiece positioning, clamping, assembly, and welding operations. Their core advantages lie in the wear resistance and stability of their high-hardness tabletops, making them suitable for flexible welding production of single pieces, small batches, and multiple varieties of workpieces. They are widely used in industries such as construction machinery, automotive parts, steel structures, and rail transit, where high welding accuracy and tooling lifespan are required.
Specifications and model number
High-hardness 3D welding table is mainly divided into two series: D16 and D28. The D16 series mostly features a 50×50mm grid spacing, while the D28 series mostly features a 100×100mm grid spacing, accommodating different sizes of tooling fixtures.
Core Design and Structure
Modular Grid System: The work surface is made of high-hardness alloy steel (often ductile iron or special steel), covered with a grid array of precisely machined holes according to a uniform standard (such as the D28 or D16 series). These holes form the basis of the system's modularity.
High Hardness Characteristics: The table body undergoes special heat treatment (such as quenching and tempering), resulting in extremely high surface hardness (typically HRC 45-55 or higher). This provides wear resistance, compressive strength, and overall rigidity far superior to ordinary steel platforms.
Three-Dimensional Expandability: Through the standard holes, various functional modules can be installed in any direction (X, Y, and Z axes), creating a three-dimensional positioning and clamping space suitable for workpieces with extremely complex shapes.
Countertop material
| Selection of mainstream materials |
(1) High-strength alloy structural steel: High-quality steels such as Q355B and 45# steel are used as the base material for the workbench surface. These materials possess excellent strength and toughness, capable of withstanding the heavy pressure and welding impact of medium-tonnage workpieces. They are the preferred material for general-purpose welding fixtures and are suitable for most conventional welding scenarios, such as those in construction machinery and automotive parts manufacturing.
(2) Wear-resistant cast iron: Using wear-resistant cast iron such as HT300 as the raw material, the inherent properties of cast iron provide superior wear resistance compared to ordinary steel. After subsequent heat treatment, it can meet the welding and processing needs of heavy workpieces (such as large steel structures and excavator chassis), making it suitable for high-load, long-term production operations.
(3) Stainless steel: 304 or 316 stainless steel is used as the workbench surface material, primarily for welding scenarios requiring corrosion resistance, such as in chemical equipment and food machinery. To improve hardness, the stainless steel surface undergoes additional surface hardening treatment, balancing corrosion resistance and wear resistance.
Products Certification
CE certification is a mandatory requirement under EU law for product safety, health, and environmental protection, and is not simply a quality certification. A product bearing the CE mark is considered a "passport" for manufacturers to enter the European market, allowing it to be freely circulated and sold legally in all EU member states.
Hardness-enhancing heat treatment process
(1) Basic Process: Quenching + Tempering. This is the standard process for strengthening the surface hardness of the tabletop. The steel of the tabletop is first heated above its critical temperature and held for a period of time before being rapidly cooled (quenching), transforming the internal structure of the steel into high-hardness martensite; then, low-temperature tempering is performed to eliminate internal stresses caused by quenching, preventing brittle cracking of the tabletop. This ultimately stabilizes the Brinell hardness of the tabletop in the range of 200–400 HB, balancing both hardness and toughness.
(2) Advanced Process: Surface Nitriding Treatment. For tabletops requiring high wear resistance and rust prevention, a surface nitriding process is added after quenching and tempering. By placing the tabletop in a nitriding furnace, nitrogen atoms are diffused into the surface layer of the steel, forming a layer of extremely high hardness. This process not only further improves the wear resistance of the tabletop but also enhances its rust resistance, extending the service life of the equipment in humid workshop environments.
Core Advantages and Features
Unparalleled Precision and Repeatability: All positioning holes and functional modules are precision-machined with minimal clearance. Once the fixture design is finalized, rapid and precise workpiece positioning is achieved, ensuring high consistency in mass production with tolerances as tight as ±0.05mm or even better.
Ultimate Flexibility and Efficiency: No need to customize complete tooling for each new workpiece. Simply utilize standard modules (stops, clamps, locating pins, support columns, angle gauges, etc.) to quickly reconfigure the fixture on the grid. This significantly reduces tooling preparation time (by over 90%), making it ideal for multi-product, small-batch production.
Effective Control of Welding Deformation: The high-rigidity table itself is resistant to deformation, while the powerful three-dimensional clamping system provides multi-point, multi-directional rigid fixation of the workpiece, minimizing thermal stress deformation during welding and reducing subsequent correction work.
Exceptional Durability and Cost-Effectiveness: The high-hardness surface is extremely wear-resistant, impact-resistant, and resistant to welding spatter, providing a lifespan of decades. Although the initial investment is higher, its flexibility and long lifespan result in very low tooling amortization costs per unit in the long run.
Improved Safety and Ergonomics: The workpiece is securely clamped, freeing the operator's hands to focus on the welding process and reducing the risks associated with handling and holding. The clean and organized work surface also improves the working environment.
