Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current welding devices in production systems require complex and error-prone manual parameter adjustments for each weld spot, especially when dealing with varying sheet metal thicknesses and special welding tasks, making startup and maintenance costly and inefficient.
Innovation Solution
A welding device with a hierarchical, multi-stage parameter structure that allows automatic parameter management based on combinations of components and welding tasks, enabling uniform parameter application across identical material properties and conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual parameter adjustments are made for each weld spot, then specific welding conditions can be addressed, but the complexity and error susceptibility increase significantly
Solution Approach 1:
The parameter structure is segmented into hierarchical levels: global parameters for identical material combinations, group parameters for specific welding tasks, and individual parameters for specific weld spots. This segmentation allows systematic management where changes at higher levels automatically propagate to dependent lower levels, reducing manual intervention and errors.
Solution Approach 2:
Global parameters are defined for identical combinations of sheet metal thicknesses and materials, serving multiple weld spots universally. When a global parameter is changed, it automatically updates all corresponding weld spots, eliminating repetitive manual adjustments and ensuring consistency across the production system.
2Adaptability or versatility
If manual adaptation of weld spots is performed for central parameter changes, then parameter updates can be made, but the time and cost increase
Solution Approach 1:
The system performs preliminary parameterization by establishing hierarchical parameter structures and defining global parameters for material combinations before production begins. This preliminary setup enables automatic parameter propagation, so when changes are needed, they are automatically applied throughout the system without requiring time-consuming manual adaptations of individual weld spots.
3Manufacturing precision
If individual parameterization of each weld spot is used, then specific welding conditions can be controlled, but the ease of operation decreases
Solution Approach 1:
The parameter structure implements a nested hierarchy where global parameters contain group parameters, which in turn contain individual weld spot parameters. This nesting allows operators to make high-level adjustments at the global level that automatically cascade down through groups to individual weld spots, maintaining precision while dramatically improving ease of operation.

AI summary
A welding device for a production system having a welding tool and a control device operatively connected to the welding tool. The control device can be configured to control the control the welding tool to connect at least two components with a welded connection with reference to a first parameter. The first parameter defines the welded connection. The control device can be furthered configured to access the first parameter for the welded connection with reference to a hierarchy, wherein the hierarchy identifies a second parameter assigned to the first parameter and the second parameter contains a third parameter, wherein the second parameter defines a welding task and the third parameter defines a first combination of values.
