The welding production line for aerial work platforms—encompassing scissor, telescopic, and articulated boom types—constitutes the core manufacturing stage for forming the structural components of the complete machine. It primarily executes processes such as material cutting, assembly, welding, straightening, and inspection for critical load-bearing structures, including chassis frames, boom assemblies, outriggers, platform frames, slew rings, and articulation joints. Characterized by high strength, exceptional reliability, minimal deformation, and a high degree of automation, this entire production line strictly adheres to the rigorous standards required for heavy-duty engineering machinery, fatigue resistance, and high-altitude operational safety.

Overall Layout and Flow of the Production Line

The typical process flow is as follows

01 Raw Material Pretreatment
02 Part Cutting and Beveling
03 Alignment and Positioning
04 Robotic / Manual Welding
05 Post-Weld Slag Removal and Correction
06 Nondestructive Testing
07 Shot Blasting for Rust Removal
08 Proceed to Machining / Painting

Scissor Arm Assembly Overview

The scissor arms of a scissor-type aerial work platform constitute the core load-bearing and lifting component of the entire machine; they are typically fabricated by welding high-strength steel plates. The dedicated welding production line for these arms represents a critical process for ensuring structural strength, rigidity, fatigue life, and product consistency. Centered on principles of automation, flexibility, and lean manufacturing, the entire production line is designed to accommodate the requirements of diverse-product, small-batch runs as well as large-scale mass production.

Process Flow: A single scissor assembly consists of inner forks, outer forks, single forks, and other components.

The production process for scissor-type welding is as follows:

• Plate Fitting and Assembly Welding

• Robotic Plate Welding

• Robotic Scissor-Arm Welding

• Scissor-Arm Touch-up Welding and Grinding.
