MAC expands range “THREE Technologies, one company” has been MAC’s company statement for decades. The company has now expanded this to four technologies, by adding laser inspection equipment for detecting welding imperfections in tube and pipe. The WI2000p laser can collect up to 250 profile images per second, providing the mill with real-time trend reporting, simplifying mill set-up, and minimising downtime and material scrap.

For customers that need 100 per cent inspection coverage of their material for defects such as cracks, slivers, inclusions and other discontinuities, MAC also offers eddy current and ultrasonic equipment that can enhance the inspection line capabilities.

This technology, produced by MAC’s partner Xiris, detects weld undercut, sunk welds, pinholes, weld height and weld register (mismatch). A high-speed video camera combined with fast data capture and analysis rates provides detection of defects down to 0.015mm in size on a typical laser welding tube mill. Weld types such as ERW, TIG and SAW, among others, are also inspected. Direct integration with the tube mill’s marking system allows for weld defects to be marked instantaneously without halting the mill.

Butt fusion welding machine RITMO machines have been used on pipe in a building site located in southern Sweden, in Halmstad. The duct will use PE 100 SDR 17, OD 160- 135mm. In order to be completed, this work will require approximately one full year, during which extreme changes in climate will occur (from -20°C in the winter, to +30°C in the summer). 400 equipped with a scanner for bar code reading and automatic detection of the welding parameters.

The welding machines are proving themselves to be trustworthy both under the sun as under Sweden’s snow. The project that is taking place is at the forefront and Ritmo is indeed opening our road.”

Kenny Constanzo, a technician from GPA said: “We have a strong sense of environment protection in Sweden, and this project has brought several environmental challenges on an every day basis. At its completion, the building site will have crossed the entire city through urban obstacles such as narrow streets, big intersections… and through “secular” obstacles such as trees… Just to give you an example, we decided to make a detour and leave a wonderful

The proximity to the sea will also affect the conditions of the wind and humidity, which can change abruptly. Moreover, the building site crosses the centre of the city and intersections with lots of traffic. The technician of GPA Flowsystems AG (Ritmo’s local distributor) suggests the contractor (MTA Bygg & Anlaggning) to work with Ritmo’s butt fusion welding machine Delta 355 all terrain, and Elektra 400 electrofusion machine. The Delta 355 all terrain allows a high level of mobility and versatility: the generator on board makes the welding machine totally independent, and the wheels assure a fast positioning. These features were highly appreciated both for the short execution time given, and because they created a minimum discomfort to the citizens. Furthermore, the Delta 355 All Terrain provides certified weldings, thanks to its welding control system – Easy Life. Wherever a butt welding was not possible, the contractor used the Elektra
