Introduction

BoomㆍLower Frame Welding Automation Solution

This line is a robotic automation system designed to safely and efficiently weld large components such as the boom and lower frame in the excavator production process at HD Hyundai Construction Equipment. Heavy parts are fed into the line via RGV (Rail Guided Vehicle), and HDR series robots work in coordination with gantries and positioners to perform precise arc welding from multiple angles. The process is fully integrated up to unloading and transfer to the next stage, minimizing operator intervention and ensuring stable automation.
This solution is engineered to handle complex welding patterns and various component sizes, delivering enhanced safety compared to manual operations, minimizing quality variations, and maximizing equipment utilization.

Key Advantages of HD Hyundai Robotics

Positioner Synchronization

When the 3-axis gantry (X, Y, R) and 2-axis positioner are combined with the robot’s 6 axes, creating an 11-axis synchronized system, the robot can achieve complex positioning for precise welding on large components with varied shapes and curved surfaces. This multi-axis synchronization maximizes the working envelope by combining gantry movement with positioner rotation, while maintaining optimal torch angles to ensure consistent weld bead quality and alignment. As a result, accessibility for challenging welds is improved, and overall quality stability is significantly enhanced.
LVS

Another key feature of this process is the robot tool designed to efficiently handle 2x3 arrangements. The gripper is capable of simultaneously picking up two containers, dramatically reducing cycle time compared to single gripping operations. It is engineered to accommodate containers of varying heights, ensuring precise handling even in environments with uneven stacking or loading variations. This capability greatly improves process efficiency and productivity while delivering high flexibility for multi-product and heavy-load operations.

Solution

The large-component welding automation solution

This is an advanced system designed to safely and accurately weld heavy parts such as excavator booms and lower frames. It integrates RGV (Rail Guided Vehicle) for part feeding, positioner centering, LVS (Laser Vision Sensor) for real-time seam correction, and multi-axis robot synchronization to handle complex welding patterns with precision. Key features include support for high-difficulty welding, minimized quality variation, enhanced operator safety, and 24-hour unmanned operation, delivering maximum productivity and consistent quality.

01

LVS

In thick plate welding, LVS utilizes laser scanning to measure gaps, angles, and positional deviations in real time, automatically correcting the robot’s path. This enables stable execution of complex welding patterns while minimizing quality variations. By achieving precision within ±0.5 mm, it significantly reduces rework and ensures consistent quality, while sensor-based data allows reliable handling of high-difficulty welds. Additionally, it greatly contributes to productivity by shortening setup time and enabling 24-hour continuous operation.

02

RGV

An RGV (Rail Guided Vehicle)-based automation solution fully automates the transport, outbound handling, and positioner centering of large, heavy components, delivering efficiency far beyond manual operations. The system safely and precisely transfers multi-ton structures while minimizing human intervention, significantly reducing labor burden and the risk of safety incidents. By dramatically shortening inter-process transfer time and performing automatic alignment and centering, it prevents downstream welding and assembly errors. This level of automation enables 24/7 unmanned operation, raising line uptime and compressing overall cycle time to substantially boost productivity. Moreover, it ensures consistent quality and process standardization, allowing manufacturers of large structures to achieve both stability and competitiveness.
