One of the main activities at MACfeam is welding, emphasing on thick wall large diameter tubulars, made from carbon, carbonmanganese, low alloy and high strength low alloy steels. Tubulars with a thickness of 20-160mm and with an outside diameter of 1.200 to 6.000mm can be handled. A specific area of expertise is the automated multi wire SAW process, applied on both longitudinal and circumferential weld seams with semi narrow gap weld preparations.

Our SA welding equipment further includes narrow gap welding heads for thicknesses in excess of 125 mm . There where access is limited or welding is forced to be performed in position, manual welding with stick electrodes (SMAW) or flux cored wire (FCAW) can be applied. Careful selection of welding consumables and establishment of stringent welding parameters enables MACfeam to achieve high quality weld seams meeting the most demanding offshore, pressure vessel and other structural fabrication specifications.
