Pipemill industry is one of the most demanding whose welding activities are predominantly based on the SAW process.

Pipemills are in the worldwide specialists in the multiarc process (3 to 5arcs).

Because of productivity requirements involved the multiarc process requires a technical set up to perform correctly. That is why Lincoln Electric R&D department designed the new SAW power source PW AC/DC 1000 to simplify the task of pipemill manufacturers. This source :

● Can be used either on DC or AC current

● Allows a continuous phase angle between the different arcs to limit or avoid arc interactions.

● Allows the increase of Deposition rate/Heat input ratio compared to a standard machine.

Uhrhan and Schwill , the world leading specialist in multiarc application for pipemills and part of the Lincoln organization, will proudly support your pipe application.

Lincoln Electric also has a full range of Flux/wire consumables originally designed for Pipemill activity dealing with either longitudinal or spiral welds.
