Flexible Welding Platform

Main features

(1) Modular D28 hole system design
Standard D28 hole spacing (28mm), compatible with various fixtures, positioning pins, and support columns.

360° adjustable fixture, can fix the workpiece at any position in the X/Y/Z direction.

Quick changeover, suitable for multi-variety, small batch welding production.

(2) High rigidity structure
High-strength cast iron/steel plate, strong deformation resistance, suitable for heavy welding.

Precision ground work surface to ensure reference flatness (≤0.05mm/m²).

(3) Three-dimensional flexible combination
Expandable splicing: multiple workbenches can be combined into a larger welding platform.

Compatible with various fixtures: such as clamps, angle adjustment blocks, V-blocks, etc.

(4) Wide application
Suitable for welding of large structural parts (such as engineering machinery, ships, bridges).

Can be used for mold manufacturing, mechanical assembly, inspection tooling, etc.

Selection Suggestions
Size Selection: Select the workbench according to the size of the largest workpiece (for example, 2000×3000mm is suitable for medium-sized structural components).

Load-bearing Requirements: For heavy-duty welding, it is recommended to choose a workbench with reinforcing ribs or a thickened type.

Expandability: If a larger working area is required, a spliced design can be selected.

Material Selection:

Cast Iron: It has good shock absorption and is suitable for high-precision requirements.

Steel Structure: It has a light weight and strong impact resistance.

Maintenance and Care
Regular Cleaning: Avoid slag and dust from clogging the positioning holes.
Anti-rust Treatment: Apply anti-rust oil (especially for cast iron platforms).
Check Flatness: Re-calibrate after long-term use.
