Welding Quality Control System Using Mobile Data Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-scale construction projects, maintaining records of individual welds and their quality across numerous welders and equipment is a daunting task due to the sheer volume and complexity of welding operations.
Innovation Solution
A quality assurance system that populates a database with welder and inspector information, using mobile terminals for real-time data entry and wireless communication, storing details like weld location, type, dimensions, and examination results, and generating reports to ensure accountability and traceability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual record-keeping methods are used for individual welds, then the system complexity is low, but the time and effort required to maintain records increases significantly
Solution Approach 1:
The patent replaces manual mechanical record-keeping processes with an automated computer-based system that electronically captures, stores, and manages weld data. The system automatically generates weld identifiers, tracks weld parameters, and maintains records in a centralized database, eliminating the need for manual paperwork and significantly reducing the time and effort required for weld record maintenance.
Solution Approach 2:
The system enables automatic self-service functionality where the computer automatically generates unique weld identifiers, populates weld data logs with relevant information, and maintains records without requiring manual intervention for each weld. The automated generation and tracking processes allow the system to serve itself, reducing the burden on personnel.
2Reliability
If detailed tracking of each weld is implemented, then quality control improves, but the complexity of the system increases
Solution Approach 1:
The patent segments the weld record-keeping system into distinct modular components: unique weld identifier generation, weld data log creation, database storage, and report generation. Each component handles a specific aspect of weld tracking independently, allowing detailed quality control through comprehensive data collection while managing system complexity through modular organization and clear separation of functions.
3Loss of information
If comprehensive weld data is collected and stored, then traceability and accountability improve, but the amount of data management required increases
Solution Approach 1:
The patent implements a universal centralized database system that serves multiple functions: storing weld data, tracking quality information, generating reports, and providing traceability. This multi-functional system consolidates various data management tasks into a single integrated platform, improving information traceability while reducing the overall complexity compared to multiple separate tracking systems.
Data Source
AI summary
A quality assurance system includes an internet/wide area network interface configured to provide bidirectional communication with user terminals; a wireless interface configured to provide bidirectional communication with mobile user terminals; and a quality assurance database cooperatively coupled with a database manager. The data base manager is configured to populate the quality assurance database with identifications of individual ones of a plurality of construction project welders, weld inspectors and a plurality of weld data logs individual ones of which are associated with a specific welding operation of a construction project. Each weld data log is configured to store information that is at least descriptive of a welder, material used during the specific welding operation, specifics of a completed weld including at least weld location, weld type and weld dimensions, and information descriptive of a weld examination. Information entry into at least one weld data log is made by a weld inspector using a report from one of the mobile user terminals.
