The new non-copper-clad filler rods have excellent wire feed properties, also with very long hose packages and high wire advance speeds. The excellent current transition in the contact nozzle is achieved with these clean wire electrodes by wetting the surface by means of a special additive (takes over the function of the very-thin copper layer). This additionally provides for sufficient corrosion protection, also in case of storage over longer periods. The performance capability of this surface finish becomes clear particularly

A new generation of bright welding wires With the development of WDI PLATINARC, we have succeeded in combining the good properties of copper-plated and non-copper-plated welding wires. The Platinarc welding consumables are characterised by therefore by: Low contact tip wear Best wire feeding properties Minimal silicate precipitation in the weld sea Low splash formation Low copper content in welding fumes Stable electric arc

WDI's welding wire production at the Hamm/Westf. and Rothenburg/Saale /Wettin.Löbejün) sites can look back on a history of almost 50 years. Unalloyed and low-alloyed inert gas and submerged arc wire electrodes have been manufactured at WDI's main plant in Hamm/Westphalia since 1975 and at WDI in Rothenburg in central Germany since 1993. Production at both sites was gradually expanded and today, with a production capacity of up to 60,000 tonnes p.a., is one of the largest production facilities for welding wires in Europe. There is hardly a steel processing company in Germany or Europe that is not familiar with the wire electrodes from Hamm and Rothenburg. Whether for manual welding in steel construction with 15-18 kg spools or for semi-automated and fully automated welding with drums of up to 750 kg wire weight, WDI has the right drum in its range for every application.

LIPP welded tanks are erected using the LIPP Welding Technology, a unique method of construction enabled by a custom automated rig designed and manufactured by LIPP. This procedure can claim a number of advantages over other traditional welding methods. Firstly, the unique steel profile increases stability and so reduces material costs at the same time. Secondly, the automated endless tape process continually welds layers below in a rotational cycle and reduces the number of on site workers. LIPP Welding Technology enables welding both black steel and stainless steel of different grades, allowing numerous applications. LIPP aims to increase construction efficiency through the implementation of unique techniques and technology, ultimately benefiting customers via a cost effective system. The key facets for the construction of a LIPP storage system are automation, continuously variable tank dimensions, reduced space requirements for onsite construction and increased worker safety.

The core of the technology is the automated welding process, where the tank is simultaneously welded on the inside and the outside. Similar to the Lipp double fold technology the material will be pre formed by Lipp special forming machines and reinforcement ribs are applied for additional stability. By doing so, the wall thickness can be reduced which will have an economic effect on the overall material costs, without compromising structural stability. The process also enables the installation of roofs and other accessories at ground level, which reduces the risk of working at heights. The main application for the new Lipp welding technology is the drinking water sector. However, there is lots of market potential in the food and beverage industry, chemicals and pharmaceuticals as well as other industries. The black steel welding technology enables the installation of bulk silos with huge diameters and volumes, which is a significant improvement compared to today.

Special features of the Lipp welding technology are the automated on site construction of above the ground cylindrical tanks made of various grades of duplex steel, stainless steel and black steel. Moreover, the technology also incorporates the post treatment of the weld and a visualized welding monitoring and the technical documentation of the process. Due to the flexible and mobile concept of the equipment, the installation can either be done on greenfield construction sites but also inside buildings or in places with limited access and working space.

FOR STORING BIOMASS TO BE USED FOR ENERGY PRODUCTION OR ANIMAL FEED The LIPP System is based on a world wide unique and genuinely simple principle of tank production. Steel coils, machines and accessories are transported to the construction site, the production of the tank takes place on site – fast, efficiently and flexibly in height and diameter. In an automated, two stage process, a profile is formed from the steel strip which is joined in a second step – at the same time, the container rotates spirally. The tight and stability supporting connection of the steel band can be effected by the LIPP Double Seam as well as the LIPP Welding Technology. Compact and space saving High functional safety Reduced retention time in the digester Reduced energy losses during storage Low maintenance and durable Automatic feeding Storage losses as a result of oxidation are avoided

GUARANTEED OPTIMUM STORAGE FOR A WIDE VARIETY OF MATERIALS The storage of bulk materials needs to be not only cost effective but also safe, and systems should be easy to integrate in production processes. LIPP Double Seam technology and welded LIPP tanks have proven to be particularly suitable for bulk storage applications in industry and agriculture. LIPP silos provide a high level of stability and total leak tightness and protect bulk materials from moisture. The smooth internal walls of the silos are a benefit that pays dividends when storing special media. All kinds of bulk materials Grain Soya Silage fodder Woodchips Pellets Clinker brick Cement SILOS FOR STORING GRAIN AND OTHER FOODSTUFFS Grain, soya and other foodstuffs are precious commodities and a major asset in agriculture and they need to be stored particularly carefully. With the tried and tested Lipp Double Seam System, Lipp silos offer major benefits in terms of design and leak tightness.
