Welding has been an important part of PSW Technology`s business for many years. PSW Technology has acquired a high level of competence and experience to comply with standards and regulations in the demanding offshore/subsea marked. Our welding shop is capable for assembly and welding of a variety of steel structures, pipe systems and special welding processes.
Our IWE is responsible for the quality and development of the welding processes and procedures. We are continuously developing new welding procedures to meet any requirements from our customers. All our welders are approved according to NS-EN ISO9606.
Submerged arc is a mechanized process, where one wire is fed through a conduit and a contact nozzle up to the welding arc. The arc and the molten pool are protected by a mineral flux supplied in front of the wire, this melts and creates a slag which also contributes to a particularly smooth and even weld surface. Submerged arc welding is suitable for most unalloyed and alloyed types of steel. The process stands out by its good welding economy, which is caused by a high deposition rate, and in general few welding defects. Submerged arc is also extensively used for cladding, where wear resistant or corrosion resistant metals are deposited onto ordinary steel.
PSW Technology performs PWHT with inhouse calibrated equipment.
PSW Solutions performes complete NDT service as part of all welding projects:
