Products Description

28mm Welding Table

The 28mm Welding Table is a heavy-duty modular welding fixture platform. Featuring a 28mm hole diameter and a 100mm x 100mm grid hole pattern, it is designed for positioning and clamping heavy workpieces and is widely used in high-precision manufacturing scenarios such as structural component welding and large equipment assembly. It serves as a core foundational equipment for flexible welding production lines.

Core Structure and Design Highlights

Modular Hole Pattern Design: The 28mm hole diameter and 100mm grid are compatible with global standard D28 series quick-change fixtures, allowing for rapid assembly of positioning blocks, clamps, support bases, etc., enabling quick tooling reconfiguration and significantly reducing changeover time.
High-Strength Rigid Structure: The tabletop is machined from a single piece of thick steel plate, with integrated reinforcing ribs and frame, reducing welding heat deformation and deflection under heavy loads, ensuring long-term accuracy and stability.
Multi-Surface Machining and Surface Treatment: 5-sided precision milling + plasma nitriding/hard chrome plating enhances surface hardness and corrosion resistance. Rounded edges (3mm) at the hole openings prevent stress concentration and extend service life.
Compatible and Expandable Design: Supports multi-unit splicing and stacking of height blocks/extension blocks, compatible with robotic workstations, positioners, and other automation equipment, meeting the needs of flexible manufacturing.

FAQ

Information about the System 28mm hole welding workbench.

Q:1.What are the core differences between a 28mm hole system welding table and a 16mm hole system welding table? How should I choose between them?

A:The core differences lie in the hole diameter, load capacity, and applicable scenarios. The 28mm hole system is suitable for heavy workpieces (single table load capacity of 3-7 tons), with a hole spacing of 100mm, and is used with heavy-duty clamps, making it suitable for engineering machinery and steel structure welding. The 16mm hole system is suitable for precise small parts, with a hole spacing of 50mm, offering higher positioning accuracy, and is suitable for automotive parts and small aerospace component assembly.

Q:2.Can plasma cutting be performed on a 28mm hole pattern welding table?

A:Yes, but it requires a dedicated cutting fixture and a dust removal system. The slag and dust must be cleaned immediately after cutting to prevent high-temperature damage to the hole walls. Frequent plasma cutting in the same area is not recommended to prevent localized deformation of the table surface due to heat.

Q:3.Can I order a custom-sized 28mm hole pattern welding table? What is the lead time for custom orders?

A:Customization is available. The table dimensions (maximum 4000×2000mm), thickness, and side height can be customized according to the workpiece size. The standard lead time for custom orders is 15-20 business days, and expedited orders can be completed in 10 business days (additional charges apply for expedited orders).

Q:4.Will the nitrided layer on the welding table surface be damaged by welding slag? Is protection necessary during welding?

A:The plasma nitrided layer has a hardness of 450-850 HV and excellent wear resistance; a small amount of welding slag will not damage the surface. However, it is recommended to lay anti-slag mats in non-positioning areas during welding to prevent large amounts of high-temperature welding slag from adhering for extended periods, which could affect hole position accuracy.

Q:5.What international certifications does the product have? Does it meet EU market access standards?

The product has passed ISO 9001 quality management system certification, CE safety certification, SGS wear resistance and precision testing, and BV product reliability certification. It fully complies with EU market access requirements, and a complete set of certification documents can be provided for customs clearance.

Q:6.How are large-sized 28mm hole pattern welding tables transported? Is there a risk of damage during overseas shipping?

A:Domestic transportation uses forklifts and flatbed trucks, while overseas transportation uses containers with wooden pallets for securing the goods. The table surface is covered with protective film, the holes are fitted with protective plugs, and the corners are wrapped with anti-collision strips. Additionally, shipping insurance is purchased, so if any damage occurs during transportation, free repair or replacement will be provided.
