What the data for this category looks like
This category’s data comes from design drawings, material quality certificates, welding equipment parameters, filler metal inventory, non-destructive testing systems, and personnel qualification ledgers. Daily documents include welding procedure qualification records, welding procedure specifications, filler metal usage records, welder qualification records, weld inspection reports, and repair orders. Data is updated per weld, per batch, or per shift. Fields include weld number, filler metal batch number, welder certification number, inspection results, repair times, and more. Units include millimeters, kilograms, hours, and others.
What constraints these characteristics impose on multi-turn dialogue and prompt engineering
Decentralized data sources require multi-turn dialogue to retrieve ledger content from different systems step by step, to avoid overloading the single context. High update frequency requires prompts to limit retrieval to recent batches or weld data, to prevent calling expired information. Multiple document types require explicit specification of specific documents such as welding procedure qualification records and filler metal usage records in prompts, to avoid mixing up data types. Strict quality constraints require embedding qualification verification logic in multi-turn dialogue, to ensure welder qualifications and process parameters meet requirements.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Maximum conversation context length | 8000–12000 characters | Welded structural component ledgers contain multiple document fields, and single-batch data volume is large, so this setting must accommodate complete multi-turn dialogue and data references |
variables binding scope | Bind all ledger fields for the current weld batch | Accurately match production data for the current session, avoid calling information from unrelated batches |
messages history retention count | Top 10 conversation records | Filter redundant history, retain key requirement confirmation and data retrieval commands, prevent context overload |
| System prompt trigger rule | Trigger based on the weld number bound to the session | Quickly locate the production ledger corresponding to the current session, no need to confirm batch information multiple times |
chatId association configuration | Bind the chatId of the current production work order | Tie conversation records to the corresponding work order, facilitate subsequent review and data export |
| Single data retrieval limit | 5 entries per request | Control the volume of data returned in a single request, avoid slow loading of the conversation interface |
Three Common Misconfigurations
- Interface prompt "No permission to operate this conversation record": The cause is failure to bind the
chatIdof the current session to the permission scope of the corresponding production work order, resulting in failed session access permission verification. - Conversation records lost after refreshing the conversation page: The cause is failure to correctly configure persistent storage for
chatIdafter upgrading FastGPT v4.17.0, the session is not bound to the production work order, and a new conversation is automatically generated after refresh. - AI prompts indicate no files uploaded but system prompt documents are configured: The cause is failure to explicitly specify category-specific documents such as welding procedure qualification records and filler metal usage records in the system prompt, the AI cannot match the configured data source.
How to Confirm Proper Configuration
- Enter a weld number, check if the conversation automatically retrieves ledger data such as filler metal usage and welder qualification for the corresponding batch.
- Check if
chatIdmatches the unique identifier of the current production work order, ensure conversation records can be reviewed. - Initiate multi-turn dialogue, confirm that only the most recent 10 key records are retained, no redundant information appears in the context.
- Trigger the system prompt, check if it automatically matches the weld batch parameters for the current session, no additional batch information input is required.
