What this category of data looks like
Data for this category primarily comes from design drawings, material quality certificates, welding equipment parameters, welding consumable warehouses, non-destructive testing systems, and personnel qualification ledgers. Daily generated documents include welding procedure qualification records, welding procedure specifications, welding consumable issue records, welder qualification records, weld inspection reports, and repair orders.
Data updates occur per weld, per batch, or per shift. Individual records include fields such as weld number, welding consumable batch number, welder qualification number, and non-destructive testing values. Some parameters must match standard units including design tolerances (unit: mm) and material strength grades (unit: MPa).
What constraints these characteristics impose on workflow orchestration
Dispersed data sources require workflows to connect to multiple system interfaces and adapt to documents and structured data in different formats. High-frequency updates require workflow trigger logic to align with real-time data flow, avoiding delayed verification. Multiple document types require workflow nodes to be configured with differentiated parsing rules to match the field structures of different documents such as welding procedures and inspection reports.
Rigid qualification and process constraints require workflows to embed mandatory verification links. Processes that fail verification must trigger exception handling branches to prevent unqualified operations from moving to the next stage.
How to configure the workflow
This configuration is based on the workflow orchestration logic of FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
variables | Bind batch-level global variables, including welding consumable batch number, welder certificate number, and non-destructive testing qualification thresholds | Matches the batch-wise data update characteristics of this category, simplifies cross-node parameter transfer |
nodeId | Configure a unique identifier for the non-destructive testing result verification node | Accurately locate abnormal links to facilitate process log review |
| Workflow trigger condition | Trigger at two process nodes: completion of welding consumable issuance and upload of non-destructive testing data | Aligns with the process-wise update rhythm of this category |
| Exception handling branch | Include two branches: qualification verification failed and required fields missing | Covers rigid constraint requirements for welder qualifications and document completeness |
| Retry mechanism | Maximum 3 retries, 60 seconds interval between each retry | Adapts to temporary network fluctuations that may occur during welding equipment data upload |
| Knowledge base association | Bind dedicated knowledge bases for welding procedure qualification records and non-destructive testing standards, return the top 5 results per retrieval | Matches the dedicated document and data standards of this category |
Three common configuration errors
- Running the workflow prompts that the welding consumable batch number field bound to
variablesis empty, triggering a verification failure error. The cause is that batch-level parameters are not preset in the globalvariablesconfiguration, and only temporary assignment is done in a single node, which cannot transfervariablesparameters across workflow nodes. - Workflow execution times out, returning status code 504. The cause is that a reasonable retry mechanism is not configured, and no timeout buffer is set when connecting to the welding equipment interface. A single request wait exceeds the system default threshold.
- The workflow cannot reference multiple dedicated knowledge bases. The cause is that multiple knowledge bases are not bound according to category association rules, only a single knowledge base is configured, and cross-knowledge base retrieval association settings are not enabled.
How to verify a correct configuration
- Trigger the simulated completion of the welding consumable issuance node, check whether the workflow starts according to the preset rules, and whether the welding consumable batch number parameter bound to
variablesloads correctly. - Intentionally enter a welder certificate number that does not meet qualification requirements, verify whether the workflow triggers the preset exception handling branch and jumps to the repair order generation node.
- Check the knowledge base association configuration, confirm that the two dedicated knowledge bases for welding procedure qualification records and non-destructive testing standards are bound, and that standard documents of the corresponding category can be retrieved.
- Simulate a single network fluctuation, verify whether the workflow executes 3 retries according to the retry mechanism, and triggers the exception branch after timeout.
