Bid Document and Quotation Preparation for Welded Structural Component Manufacturing: Multi-turn Dialogue and Prompt Engineering

Business data for welded structural component manufacturing comes from design drawings, material quality certificates, welding equipment parameters

What Data for This Category Looks Like

Business data for welded structural component manufacturing comes from design drawings, material quality certificates, welding equipment parameters, filler metal inventories, non-destructive testing systems, and personnel qualification ledgers. Data updates align with the production rhythm of each weld, batch of workpieces, or shift. Included documents are welding procedure qualifications, welding procedure specifications, filler metal usage records, welder qualification records, weld inspection reports, and repair orders.

Document fields include base metal grade, filler metal model, welder certificate number, weld length, inspection results, and more. Some fields have clear unit attributes: weld length is measured in millimeters, and filler metal usage is measured in kilograms.

Constraints Imposed by These Characteristics on Multi-turn Dialogue and Prompt Engineering

The high frequency of data updates requires that dialogue contexts sync with the latest ledger information promptly. This prevents the use of expired filler metal usage or welder qualification data.

Mixed use of multiple document types requires prompts to clearly distinguish application scenarios for each document type. This ensures that procedure qualifications referenced in bid documents match the current project.

The rigid qualification verification process requires multi-turn dialogue to trigger field checks incrementally. This prevents the use of overdue welders or mismatched filler metals.

Segmented data for individual welds means dialogue contexts should not be overly long. This avoids redundant information interfering with core quotation and document preparation logic.

How to Configure Settings

The following configurations are adapted for FastGPT v4.17.0.

Configuration ItemRecommended SettingRationale
Maximum context length800–1200 charactersMatches the total length of documents related to a single batch of bid projects, avoids loading excessive redundant data
Number of associated documents recalled per queryTop 3Corresponds to the number of core documents referenced in a single bid document, reduces information overload
Context refresh ruleUpdated per conversation turnAligns with the production data update rhythm of each shift or batch, ensures use of the latest filler metal and qualification ledgers
chatId binding ruleBound to a single bid projectEnsures dialogue contexts for the same project are not confused with those of other bid projects
variables presetPreset base metal grade and filler metal model fieldsQuickly access category-specific data, reduces operational costs from repeated input
messages history truncationRetain the most recent 5 conversation turnsControls total context length, adapts to high-frequency updated segmented business data

Three Common Configuration Mistakes

  • Empty knowledge base during dialogue. The symptom is that all content is visible on the knowledge base page, but the associated documents returned by the messages API call are empty. The cause is failure to bind the knowledge base to the current dialogue's chatId, or failure to reconfigure permission associations after migrating the knowledge base.
  • Multi-turn dialogue timeout. The symptom is a 504 status code being returned. The cause is failure to adjust the context refresh interval based on the update frequency of weld data, leading to excessive historical data being loaded for each dialogue.
  • Generated bid documents fail to verify welder qualifications. The symptom is that the document includes qualification records for overdue welders. The cause is failure to add welder qualification ledger verification rules to the prompt.

How to Confirm Configuration Is Complete

  • Initiate a test dialogue, input the parameters for a single weld, and check whether the returned associated documents include the filler metal usage records for the current project.
  • Switch between different chatId values, and confirm that contexts for different bid projects do not interfere with each other.
  • Input an expired welder certificate number, and check whether the dialogue prompts that the qualification does not meet requirements.
  • View the variables field of the dialogue, and confirm that the preset base metal grade and filler metal model are automatically populated.
