Dutch network is called a new generation of wire mesh fence, with its low price, the characteristics of fast installation by the user's favorite. Used in many fields, farms, residential, farming and so on. Dutch network consists of: mesh: high quality low carbon steel wire galvanized Dutch network performance as a raw material, galvanized, dip, spray surface treatment, corrosion-resistant galvanized with falling Dutch network, anti-UV properties, Dip thick in 0.8-1.1mm, mesh has a strong impact force, and another wave network said. Column: usually used dovetail column, specifications primarily based on customer demand, the top covered with plastic or iron rain cap, the surface can be galvanized, dip, spray choose one. Installation Accessories: mesh and the column with card access, a variety of special clamp connection, accessories according to customer's different requirements of specific design. Dutch network commonly used specifications are the following: Dutch network wire diameter 0.8-3.5mm, which can be taken to upgrade 0.5mm diameter. Dutch network length should not exceed 30m, the width should not exceed 2.0m. Dutch wire mesh production direction (or called vertical wire) spacing appropriate for the 50,100,150,200 mm, in the other direction as 50,100,150,200,300 mm wire spacing of individual galvanized Dutch network specifications, sometimes up to 400mm . Common are: 50 × 50mm, 50 × 100mm. Width of 1.2 m, 1.5 m, 1.8 m, 2.0 m. Dutch network in recent years, loved by everyone, especially the progress of the project more urgent, slow galvanized fence installation Dutch network quality, selection of Dutch network can speed progress of the project. And the Dutch network of the column if the choice of dovetail column, after the installation of the fence a little better than poor results. Great alternative Fence trend. Netherlands mesh welding process problems and solutions weldment and distribution of temperature changes on the weld metal subjected to steady state began to be paid a large heated higher temperature and then gradually cooled to room temperature, such a thermal cycle. Cause: welding current is too large, the arc is too long, due to improper welding angle. Preventive measures: reduce the structural stiffness, preheating before welding, reducing alloying, crack resistance, good selection of low-hydrogen electrodes and so on. . 2. Dutch network of welded joints major defects (1) lack of penetration welded joints incomplete penetration is not full penetration of the roots of the phenomenon. Prevention measures: a) drying rod, carefully clean the weldment with solder surface and the surrounding area; b) the use of appropriate welding current, correct operation. Cause: dirty groove, electrode diameter is too large and caused by improper operation. 3. Welded joints organizational and performance changes (for example a low carbon steel) (6) is not fusion is not fusion between weld and base metal binding phenomenon is not completely melted. Preventive measures: a) a low hydrogen type electrode and drying, remove weld surface of the oil and rust; b) preheating before welding, post weld heat treatment. b) cold cracking of welded joints cooled to a lower temperature, resulting weld cracking. Cause: bevel angle or gap is too small, blunt edge is too thick, dirty groove, welding too thick, too fast welding speed, welding current is too small, and improper operation due. (4) vent hole is soldered with air bubbles in the bath can not escape the weld solidification and left to form the hole. (5) undercut undercut along the weld toe portion of the base material produced by grooves or depressions phenomenon. (3) welding crack a) thermal cracking of the welding thermal cracking process, the welded joint of the metal cooled to a solid phase produced by high-temperature region near the weld cracking. Preventive measures: a) Carefully clean the surface with solder; b) multi-layer welding slag thoroughly between layers; This information is provided by: Ray Wang Anping Wire Mesh Products Co., Ltd.
