Application Field
Industry > Automotive, Application > Welding, Sector > Manufacturing

Process layout

Process Overview

This welding automation solution uses the Panasonic automatic welding system (TM-2000) combined with a positioner to perform underside welding on automotive cargo beds weighing over 1 ton. A robot travel axis (linear track) is applied to cover a wide working envelope.

By applying the Panasonic automatic welding system, the solution enables both high welding speed and high welding quality for arc welding automation.

In addition, the welding machine, robot, and positioner are configured as an integrated package, enabling fast installation and tuning.

Components

Robot
  • Panasonic TM-2000 S-AWP

  • 6-axis articulated robot

  • Payload: 6 kg

  • Repeatability: ±0.03 mm

  • Working range: 2,011 mm

  • Weight: 217 kg

  • Welding power source (YD-350VR1) (shared for 3-phase 50Hz/60Hz, digital control method, AC 200–220V, 48 kg)

Peripherals

STEP 2.Click the work instruction button
STEP 3.Perform arc welding
STEP 4.Click the work instruction button to change the fixing position (positioner rotation)
STEP 5.Perform subsequent arc welding

Features

High Work Efficiency and Quality

  • Assigns tasks requiring consistent quality and skill to the robot, while operators focus on loading and unloading, improving both efficiency and quality

  • Minimizes cycle time through high-speed welding execution

  • Reduces cycle time by applying logic and teaching strategies for corner-cutting and fitting motions at welding start and end

  • Enables automatic re-ignition logic in case of arc ignition failure to minimize downtime due to errors

  • Secures a wide working range and flexible welding postures by utilizing a positioner

  • Performs full welding coverage on large structures using a single robot

  • Enables easy welding in hard-to-reach positions that are difficult for operators

  • Secures high welding quality and reduces post-weld rework costs

  • Applies spatter reduction technology

  • Applies heat input reduction technology

  • Enables automatic compensation for uneven surfaces by detecting the distance between the welding torch and the workpiece

  • Enables gap correction using contact sensors

  • Ensures uniform welding quality by applying arc sensors with automatic compensation during welding


Easy Setup and Monitoring

  • Provides simple installation and monitoring functions

  • Enables fast installation and tuning

  • Eliminates the need for separate interface work by using an integrated welding system package

  • Enables fast parameter setup and easy tuning using WELD NAVIGATION

  • Secures various welding postures by linking with an external positioner

  • Shortens installation time by performing synchronized motion with other robots

  • Enables easy monitoring and record management of welding process data

Results

Key Benefits
Improved welding quality Increased productivity comparable to skilled operators
Client Feedback
For welding operations, it has become difficult to hire qualified workers, and even when training foreign labor, it still takes time to reach a skilled level. Through welding automation, we were able to perform consistent-quality welding and significantly improve productivity.
