Product Introduction

 

Arc Welding Robot for Industrial Welding Automation

CRP Arc Welding Robot is a 6-axis robotic welding solution designed for automated arc welding of carbon steel and stainless steel structural components, including machine frames, equipment brackets, and hardware connectors. With a 1.8 m working radius, flexible installation options, and welding-specific integration features, it is suitable for small- and medium-sized welding stations.

 

Welding Applications

Machine Frame Welding

Arc welding robots can automate repetitive welding operations for machine frames, helping maintain consistent robot movement and positioning across repeated production cycles while reducing variation between manually welded components.

Equipment Bracket Welding

For equipment brackets and similar fabricated components, robotic welding provides repeatable torch movement and stable positioning, making it suitable for production environments where consistent weld quality is required across multiple workpieces.

Hardware Connector Welding

The robot can support automated welding of hardware connectors and other relatively compact metal components, particularly where repetitive welding paths make robotic automation practical for improving production consistency.

Carbon Steel Structural Component Welding

CRP Arc Welding Robot is suitable for automated arc welding of carbon steel structural components, providing controlled multi-axis movement for repetitive welding operations in fabricated metal production.

Stainless Steel Structural Component Welding

For stainless steel structural components, the robot provides repeatable welding movement and flexible torch integration to support automated welding processes where consistent positioning is important.

Small- & Medium-Sized Welding Stations

With a 1,720 mm maximum reaching distance and floor, upside-down, or wall mounting options, the robot can be integrated into different small- and medium-sized welding stations according to available workspace and production requirements.

01

High-Speed & High-Precision Welding Movement

The 6-axis structure provides a large working range for multi-directional welding, while high-speed joint movement and ±0.08 mm repeatability support consistent robot positioning during repetitive arc welding operations.

02

Dual-Circuit Emergency Stop System

The robot is equipped with an independent safety emergency stop board, dual-circuit emergency stop design, and safety relay circuit to provide an additional layer of protection during automated welding operations.

03

Stable Power Supply & EMC/EMI Protection

A three-phase transformer and filtering design help reduce the impact of voltage fluctuations, while EMC/EMI protection measures are incorporated to support stable operation in the electrical environment of arc welding applications.

04

Flexible Cable, Gas & Welding Torch Integration

The robot integrates bending-resistant cables, built-in cable routing, dual gas paths, and a 44 mm inner diameter at the sixth-axis center hole to accommodate different welding torch configurations, including water-cooled and bellows-type torches.

Complete Arc Welding Automation Integration Solutions for Different Production Requirements

 

CRP combines robotic welding equipment, peripheral integration, and application-specific configuration to help manufacturers build arc welding workstations that fit their production processes and automation requirements.

Robot & Welding Equipment Integration

The arc welding robot can be integrated with related welding equipment and torch systems to create a coordinated welding workstation, with configuration determined by the customer's welding process and production requirements.

Positioner & Peripheral Equipment Matching

Positioners and other peripheral equipment can be matched with the robot to coordinate workpiece positioning and robot movement, supporting more flexible access to welding areas within an automated workstation.

Welding Workstation Integration

CRP can configure the robot, welding equipment, positioner, and related components as an integrated workstation rather than treating the robot as an isolated piece of equipment, helping customers establish a more practical automated welding setup.

Production Line Integration

For customers moving beyond a standalone welding station, the robotic system can be configured to connect with existing or planned production processes, allowing the welding operation to become part of a broader industrial automation workflow.
