COST EFFECTIVE MIG-MAG

Equipment for two recent developments in welding has been installed by Philips Welding Industries, of Eindhoven, at the Yugk & Zonen shipyard, a Dutch yard that builds roll-on/roll-off ships of 800 to 8,000 dwt and a range of general-purpose ships. This equipment enables the MIG-MAG process used by the yard to be successfully applied outside the welding sheds. One of these developments is the wire feeding station. This allows more economical wire-spools, carrying 15 to 20 kg of wire, to be used instead of the 4-kg spools previously used (which with the feeder weighted between 17 and 20 kg), while leaving the welder with less weight to carry. The arrangement, shown diagrammatically in the article, provides for a working radius of up to 15 m, normally sufficient for the types of ship built by this yard, between the feeder on the rectifier and the lightweight feeding-station; synchronising the rate of feed is easily done by the welder. The system can handle solid wires from 0.9 to 1.2 mm (diameter) and flux-covered wires up to 1.6 mm. The other development is "hot start", which facilitates the use of the MIG-MAG process in the one-side welding of butts. This device has been provided in the Philips MIG-MAG welding-sets used in the yard. The article includes some further information on the MIG-MAG process, which is used by the yard in applications where it will save costs (most fillets at Vuyk's can be more economically welded with stick electrodes), and hot-start welding and its advantages.
