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
