Welding Job Sequencer Automating Schedule Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Semi-automatic welding work cells face inefficiencies due to the need for manual adjustments of welding schedules, leading to reduced productivity and quality, as operators must stop welding to change schedules and are prone to errors in sequencing and inspection.
Innovation Solution
A welding job sequencer that automatically selects and implements welding schedules and sequences, reducing operator intervention by automating the setup and workflow, thereby minimizing errors and increasing productivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of welding schedules is used in semi-automatic work cells, then adaptability to varying welding conditions is improved, but productivity is reduced due to operator stoppages and manual adjustments
Solution Approach 1:
The system automatically monitors welding conditions and selects appropriate welding schedules without operator intervention. The work cell serves itself by using sensors to detect welding parameters and the controller to automatically retrieve and apply the correct schedule from storage, eliminating the need for manual adjustments while maintaining adaptability.
Solution Approach 2:
The system uses sensors to continuously monitor welding conditions and provides feedback to the controller. Based on this feedback, the controller automatically selects and applies the appropriate welding schedule, creating a closed-loop system that adapts to varying conditions without stopping production.
2Adaptability or versatility
If multiple welding schedules are stored and selectable in semi-automatic work cells, then adaptability to different weld types is improved, but operator complexity increases due to schedule selection and management
Solution Approach 1:
The system automatically monitors welding conditions and selects the appropriate welding schedule from stored schedules without requiring operator intervention. The work cell manages its own schedule selection based on real-time sensor data, eliminating the complexity of manual schedule management while maintaining access to multiple weld types.
Solution Approach 2:
Multiple welding schedules are pre-stored in the system with associated condition parameters. When welding conditions match predefined criteria, the system automatically retrieves and applies the corresponding pre-prepared schedule, eliminating the need for operators to manually select or configure schedules during operation.

AI summary
A semi-automatic welding work cell, including a welding job sequencer that automatically selects a welding schedule for use by an operator in the semi-automatic welding work cell. The automatic selection may be by way of elapsed time, a detection of welding operations, a detection of the amount of welding wire supplied for the welding operation, or a detection of the amount of energy supplied for the welding operation.
