D28 Steel Welding Table

D28 Steel Welding Table is a high-performance welding workbench crafted from D28 steel,a low-alloy high-strength structural steel known for its excellent mechanical properties and weldability.This type of table is specifically designed to withstand heavy loads,high-temperature welding environments,and frequent mechanical stress,making it a reliable choice in heavy machinery manufacturing,shipbuilding,and large-scale steel structure welding.

The material properties of D28 steel form the core advantage of this welding table.With a tensile strength of 470-630MPa and a yield strength of≥280MPa,it offers significantly higher load-bearing capacity compared to conventional gray cast iron platforms—capable of supporting workpieces weighing up to 50 tons or more without permanent deformation.Its low carbon content(≤0.20%)and controlled alloy elements(such as manganese and silicon)ensure good weldability,allowing on-table repairs or modifications if needed,a feature that cast iron platforms lack.

In terms of structural design,D28 Steel Welding Table typically adopts a ribbed plate reinforcement structure.The working surface is processed through milling and grinding,achieving a flatness error of≤0.08mm/1000mm,which meets the positioning requirements of medium-precision welding.Unlike cast iron platforms with integrated threaded holes,D28 steel tables often feature pre-welded nut sleeves or removable T-slot rails,enhancing the durability of connection points—critical for frequent fixture installation and removal.The surface is treated with shot blasting and anti-rust painting(or hot-dip galvanizing)to resist corrosion from welding spatter,coolant,and workshop humidity,extending the service life to 15 years or more under proper maintenance.

This welding table excels in handling extreme welding conditions.Its high-temperature resistance(up to 600℃for short periods)minimizes thermal deformation during large-scale arc welding or gas welding,ensuring stable positioning accuracy.For example,when welding thick steel plates(10-50mm),the table’s thermal conductivity(45W/(m・K))helps dissipate local heat,reducing temperature gradients and associated stresses.Additionally,its impact toughness(≥34J at-20℃)makes it suitable for harsh environments with workpiece handling collisions.

In application scenarios,D28 Steel Welding Table is particularly favored in heavy industries.In shipbuilding,it supports the welding of hull sections,withstanding the weight of large curved plates;in wind power equipment manufacturing,it provides a stable base for welding tower flanges and blade roots,ensuring dimensional accuracy of large-diameter components.Compared to cast iron platforms,it offers better ductility,avoiding brittle fracture under sudden loads,though its vibration damping performance is slightly inferior—this can be compensated by adding rubber damping pads between the table and foundation.

When paired with modular welding fixtures,D28 Steel Welding Table demonstrates strong compatibility.Its surface T-slots(commonly 18mm,22mm width)can be matched with standard clamping tools,enabling flexible positioning of workpieces of various shapes.For customized needs,the steel surface allows secondary processing(such as drilling or welding additional positioning blocks),providing greater adaptability than cast iron,which is prone to cracking during welding modifications.

In summary,D28 Steel Welding Table stands out in heavy-duty,high-strength welding tasks with its superior mechanical properties,structural durability,and adaptability,serving as a robust"workhorse"in industrial welding operations.
