Automated welding

Automated longitudinal welding up to 30 metres

CLOOS longitudinal systems run continuous seams along sidewalls, roofs and underframe assemblies up to 30 metres, with the structure clamped in a dedicated welding jig for the full length of the seam. AMM designs and builds those jigs in its own engineering department.

Non-destructive testing

Six non-destructive testing methods

Six methods cover the surface and the internal condition of a weld without cutting the structure.

  • Visual testing (VT)

    Direct and aided examination of weld surface, profile and geometry.

  • Penetrant testing (PT)

    Coloured penetrant draws out surface-breaking cracks and pores on aluminium and steel.

  • Magnetic particle testing (MT)

    Magnetic particles reveal surface and near-surface indications in ferromagnetic steel.

  • Ultrasonic testing (UT)

    Ultrasonic pulses locate internal discontinuities in thicker sections.

  • Radiographic testing (RT)

    Radiography records the internal condition of a weld as an image.

  • Leak testing (LT)

    Leak testing proves tightness on closed welded assemblies such as tanks.
