ISO 13919 reference
Weld Quality Standards Matrix
Quality-level references for steel, nickel, titanium, aluminum, magnesium, and pure copper laser beam welded joints.
Standard familyISO 13919
Separate steel/nickel/titanium from aluminum-family quality references.
Decision pathVisible -> section
Use visual checks to screen, then cross-section or test where the risk is hidden.
Proof packagePhotos + dimensions
Tie each accepted parameter range to measured weld evidence and sample identity.
Select the quality reference by material scope
Use ISO 13919 references to structure imperfection-quality discussions for electron and laser beam welded joints. The applicable quality level, inspection method, and acceptance decision still have to come from the drawing, contract, or responsible engineering specification.
- Use ISO 13919-1 for steel, nickel, titanium, and their alloys.
- Use ISO 13919-2 for aluminum, magnesium, their alloys, and pure copper.
- Do not use the table in place of product-specific acceptance criteria or the test plan specified by the project.
ISO 13919 material scope and inspection use
This table keeps the quality reference choice visible before defect charts or calculator outputs are interpreted.
| Reference | Material scope | Quality decision supported | Project acceptance input |
|---|---|---|---|
| ISO 13919-1:2019 | Steel, nickel, titanium, and their alloys in electron and laser beam welded joints. | Imperfection quality-level selection and terminology for weld quality discussions. | Drawing requirement, selected quality level, inspection method, sample location, and application risk. |
| ISO 13919-2:2021 | Aluminum, magnesium, their alloys, and pure copper in electron and laser beam welded joints. | Imperfection quality-level selection for the covered non-ferrous material scope. | Material specification, joint design, selected quality level, inspection method, and acceptance authority. |
| Visual examination | Surface-visible conditions on the accessible weld side. | First screening of cracks, pores at the surface, undercut, spatter, oxidation, and start/stop condition. | Lighting, magnification where used, photo method, sample identity, and pass/fail criteria. |
| Cross-section or other specified test | Hidden fusion, penetration, pores, cracks, and heat-affected-zone features. | Confirmation that the accepted setting meets the joint geometry and defect criteria. | Cut location, preparation method, measurement fields, sample count, and acceptance rule. |
Quality standard mapping
| Reference | Material scope | Shop-floor value |
|---|---|---|
| ISO 13919-1:2019 | Electron and laser beam weld imperfections for steel, nickel, titanium, and their alloys. | Compare cracks, pores, undercut, shape deviations, and other imperfection classes. |
| ISO 13919-2:2021 | Electron and laser beam weld imperfections for aluminum, magnesium, their alloys, and pure copper. | Applies when lightweight or high-conductivity materials move outside steel assumptions. |
| Visual inspection | Top bead, root condition, spatter, oxidation, undercut, and start/stop marks. | Fast first filter before cutting samples. |
| Cross-section | Penetration, fusion boundary, HAZ width, pores, and crack evidence. | Confirms whether the parameter window matches the joint target. |
Imperfection action matrix
| Imperfection | Checks to make | Next engineering action |
|---|---|---|
| Cracks | Material susceptibility, restraint, contamination, thermal strategy, and weld sequence. | Stop the window expansion, check material and restraint assumptions, and section the failed sample. |
| Pores | Surface contamination, moisture, oxide condition, shielding coverage, and keyhole stability. | Repeat after cleaning and gas verification before changing the power-speed pair. |
| Undercut | Toe profile, edge gap, power density, focus position, and beam alignment. | Check toe profile and fit-up, then adjust travel behavior or focus in one step. |
| Lack of fusion | Delivered heat, oxide barrier, focus position, gap, heat sinking, and path alignment. | Confirm focus and joint prep, then increase heat input carefully and section again. |
| Excess reinforcement or width | Delivered heat, travel behavior, spot size, filler or melt volume where used, and joint support. | Reduce heat input or tighten focus while checking penetration does not fall below target. |
Inspection record
| Record item | Record content | Decision supported |
|---|---|---|
| Visual photo | Top bead, root/access side where visible, start/stop, and any rejected defect. | Confirms surface repeatability and visible imperfection trend. |
| Cross-section | Penetration, width, fusion boundary, HAZ width, pores, and crack evidence. | Confirms whether the calculator estimate matches the real joint. |
| Parameter record | Power, speed, focus, spot size, gas, fixture, material batch, and sample ID. | Allows another setup to reproduce the accepted sample set. |
| Rejection boundary | The low/high settings that failed and the defect that appeared. | Defines the usable process window instead of only recording a single passing recipe. |
