About us

The company Neweld was founded more than twenty years ago, thanks to the willingness and desire of a group of people, with several decades of experience, to utilise and spread the results of welding metallurgy, with special reference to filler materials used for corrective and repair welding jobs, for pro-duction and maintenance, as well as for the entire field of brazing and soldering.

From the very beginning, Neweld demonstrated itself as an agile and dynamic company, well capableof following and satisfying the needs of its customers in a globally active manner, accompanied by re-lentless searching for QUALITY, BEST SERVICE, and FLEXIBILITY IN OPERATIONS.

These were the characteristics and inspirations which motivated Neweld, early as 1996, to be among the first three companies of this sector in Italy to obtain certification under the UNI EN ISO 9002:1994 standard concerning quality assurance certificates. In 2003, Neweld again went through an adjustment procedure and was approved also under the more stringent UNI EN ISO 9001: 2000 VISION standard for quality assurance systems, and in 2008, received the most advanced certification of quality assu-rance under the UNI EN ISO 9001: 2008 standard.

Since 1998, Neweld has entered the sector of soldering and brazing, and started to manufacture rings, plates, washers, and pre-formed parts for the purpose of brazing and soldering with any type of alloy, either ferrous or non-ferrous metals and, during the years, has become one of the leading companies in the production of these particular components, to the extent that nowadays the company’s production capacity exceeds 50 million pieces per month.

However, the market has started to become global, and a number of companies, which have, up untilthat time, has been present with their products exclusively on the Italian market, started to outreach forother countries of Eastern Europe and/or South America, or often asked Neweld to help them to start up their production close to the new plants. This is how in 2002, the first new headquarters abroad, NEWELD POLAND, was opened.

Today, thanks to this continuous development and the international DNA, Neweld is present in several countries either directly, via its affiliated companies, such as POLAND, SERBIA, and HUNGARY, and indirectly via retailers and dealers, or specialised persons in BRAZIL, ARGENTINA, CHINA, and the UNITED STATES OF AMERICA.

This production capability, and the presence in the most important countries of the emerging world, itsconstant quest for quality and service, make Neweld the ideal partner for all industrial companies whichlook for excellence with regard to their suppliers and partners.

Perfect to weldability in all position, except vertical down. Excellent mechanical properties of weld metal at low temperature makes application of this electrode suitable for quality structural works, like: bridges, pressure vessels, ship-building, methane pipeline, off-shore structures, chemical and petroliferous industry. Low hydrogen content of weld metal gives an high cold crack resistance and Charpy-V strength down to –46 C°.

Electrode utilized in the maintenance and for repairing parts constructed with steel structured works and construction steels. It is used as a substitute for basic electrodes, in particularly when there is a joint, that needs high mechanical resistance, in order to resist stress and high tension. Low heat on surfaces, it can be used as an underlay for coating against wear. It is suitable for joining arms and digger levers; also well suited for coating shafts and electric engine.

An electrode for pad welding protecting from wear owing to a high resistance to dynamic loads and an excellent resistance to compression. The added material is a highly alloyed material, without fractures, when it is necessary to supply a small amount of heat. It is especially recommended for applying a second layer to parts working in high temperatures. It is easily applied; it has nice welding sequences and easily removable scales. It welds in all positions and it enables grinding.

An electrode for welding of Hastelloy C alloys with an excellent corrosion and hot oxidation resistance. Owing to this feature, it is particularly recommended for electrochemical etching using sulphuric acid. A choice of quick welding cycle is recommended and during welding using manual electrodes low parameters and low current should be chosen and quick and gentle passes should be made without vibrations. It is also used for welding of heterogeneous materials such as carbon steels and steels of the Hastelloy type as well as for pad welding on carbon steels.

Tubular electrode containing tungsten carbide powder. Deposit resistant do intense abrasion. Composed mainly of tungsten carbide in an austenitic stainless steel drive. It is indicated for the charging of austenitic steels and not-austenitic, it is for cast iron and alloy steels. It is also suitable for materials subject to strong abrasion, in the presence of soft rocks, coal, coke. Good merger, and excellent metal bath. Possibility of adding a second electrode in an arc (double intensity). Suitable for charging buckets, screw conveyors, blades of attack choppers, grinders, hammers, drills and probes gear.

An electrode with a basic coating for welding of bronzes with 9, 12.5, and 14% of aluminium with an added material containing copper and aluminium (8 %). Most often it is used for applying of a second layer to all parts made from bronze, copper, steel alloys, and cast iron, which must undergo wearing due to corrosion, as a result of acid and sea water action or friction under high pressure (e.g. vessel bolts and shafts, pumps, pump casings, steam engine bearings and cases, elements of taps, cocks, etc.).
