Product Q&A

Q:Why does AWS D1.5 standard greatly improve the fatigue resistance of main bearing girder?

AWS D1.5 is the exclusive bridge welding code with strict regulations for fracture-critical members. It enforces weld toughness testing, tight undercut tolerance and full NDT inspection, eliminating welding defects that easily generate fatigue cracks under cyclic heavy load.

Q:Can the fatigue load grade of this main bearing girder be customized?

Yes. We adjust steel plate thickness, internal stiffener layout and welding process according to clients' actual traffic frequency and vehicle weight to meet different fatigue load design requirements.

Q:What NDT tests will be carried out on the main girder welds?

All key load-bearing welds pass magnetic particle testing (MT) and ultrasonic testing (UT) as required by AWS D1.5; full test reports with inspection photos will be provided with goods for project acceptance.
