Radiography, penetrant, magnetic particle, ultrasonic, and visual testing for welds and components in shop and field — documented to API and ASME standards.
Industry
Bridges, Railroads & Water Towers
Weld and thickness inspection for bridge steel, railroad structures, and elevated water towers.
SIS inspects bridge steel, railroad structures, and elevated water towers with the weld and thickness methods used on pipeline and facility work. Crews run magnetic particle, ultrasonic, radiographic, penetrant, and visual testing on welds and connections, plus ultrasonic thickness surveys on water tower shells, risers, and support columns. Work follows AWS structural welding requirements and the procedure the owner or engineer of record specifies.
SIS inspects bridge steel, railroad structures, and elevated water towers. Crews use the weld and thickness methods they already run on pipeline and facility jobs, applied to structural members, connections, and tank shells.
Magnetic particle and ultrasonic examination cover bridge and rail welds. Radiographic testing is available where access and the procedure allow. Water tower work adds visual inspection and ultrasonic thickness surveys on shells, risers, and support columns.
Work follows AWS structural welding requirements and the procedure the owner or engineer of record specifies. Reports document weld quality, thickness readings, and indications in the format that program requires.

FAQ
Common questions
What structures does this cover?
Bridge steel, railroad bridges and other steel rail structures, and elevated water towers. Typical items are welds, connections, shells, risers, and support columns.
What inspection methods does SIS use?
Magnetic particle, ultrasonic, radiographic, penetrant, and visual testing on welds, plus ultrasonic thickness surveys on water tower shells and supports. Welder qualification testing is available when the job requires it.
What codes apply?
AWS structural welding requirements and the procedure the owner or engineer of record specifies. Technicians hold the same ASNT SNT-TC-1A certifications SIS uses on oil and gas work.
