{"id":59,"count":4,"description":"Nitrided welding tables for demanding applications<\/b>\nEXTREME System 28 Series welding tables are designed for intensive welding, assembly, and production work. Their main distinguishing feature is a steel tabletop subjected to a nitriding process, which increases surface hardness and wear resistance. A nitrided welding table prepared in this way performs well in demanding welding environments, where the working surface is regularly exposed to the movement of heavy components, scratches, high temperatures, and spatter. \n\nSystem 28 uses 28 mm diameter holes and is primarily designed for clamping larger and heavier structures. By comparison, System 16 is used mainly for smaller and more precise components. \n\nThe EXTREME series combines a modular clamping system with increased tabletop surface durability. As a result, the table can be used both in single-unit production and during repetitive tasks that require accurate component positioning. \nWhat does table nitriding involve?<\/b>\nNitriding is a thermo-chemical treatment process during which the surface layer of the material is saturated with nitrogen. As a result, a hardened layer is formed on the steel surface, offering higher hardness and wear resistance than untreated material. \n\nThe nitriding process primarily affects the surface properties of the tabletop. It does not make the table entirely resistant to damage, but it helps reduce the effects of daily use. The nitrided surface wears down more slowly during the frequent moving of components, mounting of tooling, and cleaning of the table. \n\nThe key benefits of nitriding include:\n\n \thigher surface hardness,\n \tincreased resistance to wear,\n \treduced susceptibility to scratches,\n \teasier removal of some spatter,\n \textended durability of the working surface,\n \tbetter corrosion protection,\n \tlonger retention of the tabletop's functional properties.\n\nNitrided welding tables are a good solution for facilities where a standard steel surface wears out quickly due to intensive work.\nResistance to welding spatter and arc strikes<\/b>\nDuring welding, the table surface remains in contact with hot spatter and the electric arc. Welding spatter can adhere to the tabletop, settle in the system holes, and make the proper mounting of pins and clamps difficult. \n\nA nitrided surface can reduce the adhesion of welding spatter and make it easier to remove. However, this does not mean complete resistance to welding spatter and electric arc strikes. The table still requires regular cleaning and proper operation. \n\nIn demanding welding conditions, particular importance is placed on:\n\n \tsystematic removal of spatter,\n \tcleaning mounting holes,\n \tavoiding heavy grinding of the tabletop,\n \tpreventing prolonged overheating of a single area,\n \tmonitoring the condition of the surface layer.\n\nProper maintenance limits the degradation of the nitrided steel layer caused by spatter, heat, and mechanical processing.\nSystem 28 for large and heavy structures<\/b>\nSystem 28<\/a> is based on system holes with a diameter of 28 mm. They enable the mounting of pins, clamps, stops, squares, and other elements of modular tooling. \n\nA regular grid of holes allows extending the functionality of the workstation and creating configurations adapted to a specific project. Accessories can be repositioned depending on the size, shape, and position of the workpiece. \n\nSystem 28 provides:\n\n \tprecise clamping of heavy elements,\n \tstable positioning of structures,\n \tfast positioning of profiles, pipes, and sheets,\n \tthe possibility of working in multiple configurations,\n \trepeatability during series production,\n \tconvenient changing of tooling,\n \thigh functionality of the workstation.\n\nThe hole system also facilitates replicating the same clamping layout when producing subsequent units of a structure.\nSteel tabletop and precise working surface<\/b>\nThe tabletop is the main working surface of the welding table. It transfers loads resulting from clamping, positioning, assembling, and processing workpieces. Therefore, when selecting a table, attention should be paid not only to its dimensions, but also to its flatness, tabletop thickness, supporting structure, and allowable load. \n\nIn a series designed for heavy-duty operation, the key factors are:\n\n \tsurface hardness,\n \tdurability and wear resistance,\n \ttabletop flatness,\n \tdimensional stability,\n \taccuracy of hole manufacturing,\n \theat resistance,\n \tstrength of the steel structure.\n\nParameters such as steel grade, tabletop thickness, table height, or exact dimensions should always be checked in the specifications of a specific variant. This also applies to models with a surface area of 2400 \u00d7 1200 mm, a height of approximately 850 mm, a 100 mm pitch, or those made of S355J2+N steel. \nFlatness and dimensional stability during welding<\/b>\nThe precision of welding operations depends on maintaining the geometry of the working surface. Tabletop flatness directly affects workpiece positioning, clamping quality, and the accuracy of the finished structure. \n\nIt should be noted that nitriding increases the hardness and wear resistance of steel surfaces, but does not eliminate the risk of deformation. Excessive load, uneven heating, or prolonged exposure to high temperatures can affect the tabletop geometry. \n\nSteel has a specific coefficient of thermal expansion, which is why the table structure should operate under conditions that account for heat effects. Proper thermal expansion does not imply complete immunity to localized overheating. Prolonged exposure to high temperatures can lead to stresses, deformations, and, in extreme cases, surface damage or component cracking. \nAccessories and modular clamping system<\/b>\nA System 28 welding table can work with a wide range of accessories. System holes allow tooling to be mounted at selected points across the table surface, making it easy to adapt the workstation to the task at hand. \n\nAmong the most commonly used components are:\n\n \tclamping pins,\n \twelding clamps,\n \tstops,\n \tsquares,\n \tlocating elements,\n \ttoggle clamps,\n \tV-blocks,\n \tpipe and profile mounts.\n\nThe pin is used to insert and lock compatible components into the holes. The clamp stabilizes the workpiece, the stop creates a reference point, and the square allows the structure to be set at the required angle. \n\nThe modular nature of the system allows the workstation to be expanded as production needs change. There is no need to build a separate assembly fixture for every new structure. \n2D and 3D System 28 Welding Tables<\/b>\nA nitrided table can come in a 2D or 3D variant. The 2D construction features system holes primarily on the top surface of the tabletop and is designed for clamping components in a single main plane. \n\nA 3D table features additional side surfaces with holes. This allows components to be clamped across multiple planes and enables the creation of more complex workstation configurations. \n\nThe choice of variant depends on the type of structures being fabricated. Simpler frames and flat assemblies can be processed on a 2D surface, whereas complex spatial projects require greater positioning capabilities. \nAvailable models of EXTREME System 28 welding tables.<\/b>\nVarious configurations of Series EXTREME System 28 tables are available in the POS-MET product range.\n\nMost popular models:\n1500 \u00d7 1000 mm welding table<\/b>\nModel available exclusively with a 25 mm thick tabletop, with a load capacity of 4,000 kg. It is suited for applications requiring maximum surface hardness and durability on a smaller workstation. \n2000 \u00d7 1000 mm welding table<\/b>\nA universal nitrided table available with a 15 or 25 mm tabletop, with a load capacity of 4,000 kg \u2014 a solid choice for regular production and assembly of medium-sized structures.\n2400 \u00d7 1200 mm welding table<\/b>\nModel with a tabletop available in a thickness of 15 or 25 mm, equipped with 4 legs and a load capacity of 4,000 kg. It is suited for structural fabrication requiring a large working surface and high tabletop resistance to heavy-duty use. \n2990 \u00d7 1490 mm welding table<\/b>\nThe largest and most durable model in the EXTREME Series. Available with a 15 or 25 mm tabletop, equipped with 6 legs, and offering the highest load capacity in the entire range at up to 6,000 kg \u2014 designed for the heaviest industrial structures. \nHow to maintain a nitrided tabletop?<\/b>\nA nitrided table is resistant to daily wear and tear, but its surface can still suffer damage. Degradation of the nitrided layer can result from heavy grinding, severe impacts, the use of improper tools, or prolonged localized overheating. \n\nTo extend the lifespan of a welding table, you should:\n\n \tregularly remove welding spatter,\n \tclean system holes,\n \tavoid grinding directly on the tabletop surface,\n \tavoid heavy impacts with heavy components,\n \tdo not exceed the maximum load capacity,\n \tmonitor flatness and surface condition,\n \tprotect the table from prolonged moisture.\n\nNitriding provides protection against corrosion and spatter adhesion to a greater extent than an untreated surface, but it does not replace proper maintenance. Damage to the surface layer can locally reduce its resistance. \nWhy Choose the EXTREME System 28 Series?<\/b>\nThe EXTREME System 28 Series is designed for users who expect a durable, precise, and comprehensive workstation for welding tasks. The combination of the 28 mm hole system with a nitrided surface increases the tabletop's resistance to heavy use and allows for convenient clamping of larger structures. \n\nKey advantages of the series:\n\n \tnitrided working surface,\n \thigher surface layer hardness,\n \tresistance to wear and scratches,\n \tlimited spatter adhesion,\n \tmodular System 28,\n \tprecise clamping,\n \tdurability and resistance in demanding conditions,\n \texpandability with additional accessories,\n \thigh workstation functionality,\n \tsuitable for heavy structures.\n\nA nitrided welding table helps maintain an efficient and accurate workstation during intensive production. To select the appropriate dimensions, tabletop thickness, hole pattern, and equipment, you should compare the technical parameters of the available variants in the EXTREME System 28 Series.
