Solution Overview

Problem

Existing welding condition management systems require manual collection and summarization of welding data, leading to inefficiencies and reduced operation rates due to the need for manual creation of welding condition records, which differ from actual conditions used in production.

Innovation Solution

A system and method for managing welding conditions through a terminal device that acquires and corrects teaching programs and welding history data, automatically generating welding condition tables to streamline the management process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual collection and summarization of welding data is performed, then welding condition records can be created, but operation rates decrease and inefficiencies occur

Engineering Contradiction:

Improveaccuracy of welding condition recordsVSAvoidoperation rate

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system enables automatic self-recording of welding conditions by the welding robot itself. The teaching program correction information and welding history data are automatically generated and stored without requiring manual intervention, allowing the system to serve itself in terms of data collection and management.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical process of data collection and record-creation with an automated electronic system. The terminal device automatically acquires teaching program correction information and welding history data, extracts welding conditions, and generates management data electronically, eliminating the need for manual data entry and summarization.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If manual creation of welding condition records is required, then comprehensive welding data can be captured, but data collection time increases

Engineering Contradiction:

Improvecompleteness of welding dataVSAvoiddata collection time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary action by automatically acquiring and storing teaching program correction information and welding history data during the welding process itself. This preliminary data collection eliminates the need for subsequent manual data gathering, as all necessary information is captured in real-time or near-real-time during production.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by automatically acquiring welding history data that reflects actual welding execution results and teaching program correction information. This feedback loop ensures that the welding condition management data accurately reflects real-world operations without requiring manual verification or additional data collection steps.

Inventive Principle:

Principle #23Feedback

AI summary

A welding condition management method is a welding condition management method performed by a terminal device, and the welding condition management method includes: acquiring a second teaching program created by correcting a first teaching program for causing a welding robot to execute welding, and welding history data related to the welding executed by using the second teaching program; and extracting and outputting a welding condition at the time of the welding based on the second teaching program and the welding history data.
