Automation of Welding for Construction Machinery Parts

Securing highly skilled welders has always been a concerning issue in manufacturing sites. HD Hyundai Robotics' welding automation solution enables more effective welding through sensing technology and mechanism control that enhance precision. In particular, by utilizing positioners and gantries for large components, it supports optimal welding across a variety of positions and angles. Donghae Machinery is a specialized manufacturer of heavy equipment parts and has improved production efficiency by introducing automation solutions from the early stages. We introduce the HA006B, which is carrying out welding automation.

Introduction

Automation of Welding for Construction Machinery Parts

This solution is designed to facilitate mass production at a low cost and with minimal requirements. Once the welding target part is precisely positioned and secured on the worktable, the robot can perform welding operations reliably and consistently.

Key Feature

Key Advantages of HD Hyundai Robotics

  • Robot Arc Welding System

    The robot welding system, which secures the workpiece on the worktable, enables high-quality welding through precise position control. It enhances stability and efficiency in repetitive tasks and improves safety by eliminating the need for direct access by the operator.

  • Auto Nozzle Cleaning

    Auto nozzle cleaning is a system in which the welding robot automatically cleans the nozzle after a preset time interval or following a welding pass. This process uses tools such as wire cutters, brushes, air blowers, and silicone oil applicators to remove spatter—molten metal droplets generated during welding—from inside the nozzle. It helps maintain the cleanliness of the electrode tip and nozzle, thereby improving welding quality and extending the lifespan of both components.

Solution

Arc Welding Solution

Robotic arc welding automation consistently maintains welding quality, thereby enhancing product reliability. It also delivers high productivity in repetitive tasks, maximizing operational efficiency. A key advantage is its ability to reduce operator risk while cutting down on labor costs.

 

01

Repetitive Welding Using a 6-Axis Robot and Custom Worktable

By using a six-axis welding robot paired with a specialized worktable, welding components can be easily secured. Under preset conditions, the robot performs repetitive tasks with precision and zero deviation.

 

02

Reliable Robot Operation

This system is praised for its near-zero malfunction and failure rate, as well as its extremely low defect rate in welding. In particular, HD Hyundai Robotics' excellent after-sales service and system engineering support allow users to adopt automation with confidence and peace of mind.
