Repair Weld Inspection Thresholds for Consistent Quality Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current repair welding inspection methods lack stability in quality due to operator skill variations and require different inspection conditions for main welding and repair welding, leading to inefficiencies and inconsistent results.
Innovation Solution
A repair welding inspection device and method that acquires a second threshold specific to repair welding, distinct from the threshold used for main welding, to determine the quality of welded portions after repair welding, improving quality and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the first threshold (determination threshold for main welding inspection) is used for repair welding inspection, then the inspection process is simplified, but the quality consistency and accuracy of repair welding inspection deteriorate
Solution Approach 1:
The patent segments the inspection threshold into two distinct parts: a first threshold for main welding inspection and a second threshold for repair welding inspection. This segmentation allows each threshold to be optimized for its specific inspection context, ensuring that repair welding is evaluated with criteria appropriate to its unique characteristics rather than using a generic standard.
Solution Approach 2:
The patent applies local quality by setting different determination thresholds for different inspection scenarios. The second threshold is specifically tailored for repair welding inspection, allowing the inspection system to adapt its criteria to the local context of repair work, which may have different quality requirements compared to initial welding.
2Adaptability or versatility
If operator skill variations are relied upon for repair welding inspection, then flexibility in inspection is maintained, but quality stability deteriorates
Solution Approach 1:
The patent implements an automated inspection system that performs repair welding inspection independently without relying on human operators. The system uses the second threshold to automatically determine whether repair welding meets quality standards, eliminating the variability introduced by different operator skills while maintaining consistent, reliable inspection results.
3Ease of manufacture
If the same inspection threshold is used for both main welding and repair welding, then the inspection method is simplified, but the inspection accuracy for repair welding deteriorates
Solution Approach 1:
The patent introduces dynamic adaptability by switching between different thresholds based on the inspection context. The system dynamically selects the second threshold when performing repair welding inspection, allowing the inspection criteria to adapt to the specific requirements of repair work rather than using a static, one-size-fits-all approach.
Data Source
AI summary
A repair welding inspection device includes a memory that stores instructions and a processor that executes the instructions. The instructions cause the processor to perform acquiring a second threshold, which is different from a first threshold which is a determination threshold for inspection of welding performed before performing repair welding, and the second threshold being a determination threshold for inspection of the repair welding, and performing inspection after the repair welding by using the second threshold.
