Xometry's standard for weld joints is intended to establish a baseline for weld joint workmanship for metal parts. Weld finish is important to subsequent finishing operations, mating fitment, and overall quality perception.
Xometry’s Standard for Weld Joints
- Weld joints should be finished as specified within the weld symbol of the drawing.
- Welds without specified finish requirements shall be cleaned to remove slag or other surface contamination.
- If required, welded joints shall not be painted until welding has been completed and the weld is accepted.
Weld thickness may be specified in a customer drawing. Carefully review job details and review for welding specifications before completing welding operations. Review the workmanship of welded joints. If welded joints do not meet this standard or any superseding customer specifications, the parts should be reworked or remade as appropriate before shipping to the customer. Contact Xometry’s Case Management team with any concerns by selecting “report an issue” in the portal for the job in question.
Meets Xometry's Quality Standard
The example above exemplifies Xometry’s weld joint standard. All weld joints have been cleaned and are finished to drawing specifications.
Does Not Meet Xometry's Quality Standard
Slag, scale, and corrosion at weld joints are not permissible. Slag shall be removed from all completed welds. Welds and adjacent base metal shall be cleaned by brushing or other suitable means. Tightly adherent splatter remaining after cleaning operations is permissible unless its removal is required for the purpose of non-destructive testing.
