Industry Focus
Steel Fabrication & Structural
Incoming inspection. Weld qualification. Third-party certification.
How QML Serves This Industry
Steel fabricators and structural contractors rely on QML to verify that incoming plates, sections, and tubes meet specification — and that welded joints achieve the required mechanical properties. Our independent test reports are accepted by third-party inspection agencies, PMC consultants, and statutory bodies for project certification.
Testing Scope for Steel Fabrication & Structural
Every testing requirement matched to what QML does and the applicable standard.
| Testing Requirement | What We Do | Standard |
|---|---|---|
| Incoming plate / section grade verification | OES elemental analysis — C, Mn, Si, S, P, Cr, Ni, Mo, V against IS 2062 / IS 8500 | IS 8811 / ASTM E415 |
| Tensile properties of structural sections | UTS, yield, elongation on flat or machined specimens from plates & angles | IS 1608-1 / ASTM A370 |
| Bend test for ductility | Guided bend test — face, root, side bend on weld coupons and base material | IS 1599 / ASTM E190 |
| Weld procedure & welder qualification (PQR / WPQ) | Macro section, hardness survey, tensile, bend — supporting PQR documentation | ISO 15614-1 / IS 7307 |
| Hardness survey of weld & HAZ | Vickers HV10 traverse across weld, fusion line, HAZ, and base metal | BS EN ISO 9015-1 |
| Microstructure of as-welded & PWHT zones | Etched cross-section microscopy — phase, grain, defect identification | ISO 17639 |
| Surface coating / paint adhesion & corrosion resistance | Salt spray test for painted or galvanised fabrications | ASTM B117 / ISO 9227 |
