Weld line: appearance + performance
Keep cosmetic and functional results separate. The responsible engineering and quality owners define the evidence and acceptance requirements.
Part / sample identity
Part + revision / material grade + lot / mold + cavity / trial or production group / sample IDs / molding and inspection references
Location and function
Observed line map / gate, opening, or attachment feature / observed versus predicted location / relevant function or load question
Appearance requirement and result
Visual reference / face, viewing method, and sample condition / inspected + affected counts / individual result attachment
Performance requirement and result
Test or analysis reference / specimen identity / conditioning and loading or exposure conditions / result or pending status / owner
Evidence scope
Material data, standard specimen, simulation, or actual component? / model or test revision / what is covered and what is not
Trial comparison
Change or trial ID / same-method comparison / cosmetic result separately from performance / other required checks / unresolved evidence
Decision / next action
Engineering question / required evidence / owner + review time / current sample and product disposition reference
