When it comes to the iron guardrail, we are all familiar with it. It is very common in our daily life. How much do you know about it? Do you know the method of welding the guardrail? Next, follow the iron guardrail manufacturer to have a look, hoping to help you.

　　1、喷焊

　　1. Spray welding

　　喷焊是利用热源将金属或非金属材料加热到熔化或半熔化状态,用高速气流(喷枪)将被吹成小颗粒(雾化),和喷雾铁艺护栏的表面,形成一个坚实的涂层表面处理方法。

　　Spray welding is to use heat source to heat metal or non-metallic materials to melting or semi melting state, and use high-speed airflow (spray gun) to be blown into small particles (atomization), and spray iron fence surface, forming a solid coating surface treatment method.

　　这种方法可以使铁艺护栏的表面获得各种不同硬度、耐磨性、耐腐蚀性、抗氧化性、润滑性等特殊的物理化学性能。许多材料(金属、陶瓷、塑料、水泥、石膏、木材等)可以喷涂在表面。

　　This method can make the surface of iron guardrail obtain different hardness, wear resistance, corrosion resistance, oxidation resistance, lubricity and other special physical and chemical properties. Many materials (metals, ceramics, plastics, cement, gypsum, wood, etc.) can be sprayed on the surface.

　　为了提高喷层和基材之间的结合强度,降低涂层的孔隙率,热源可用于热喷涂层融化,因此熔喷层和金属的合金基材可以溶解和扩散,形成冶金结合类似于钎焊。这种工艺称为喷焊，由此得到的涂层称为喷焊层。这是铁栅栏焊接的两种方法——喷焊。

　　In order to improve the bonding strength between the spray layer and the substrate and reduce the porosity of the coating, the heat source can be used for the melting of the thermal spray coating. Therefore, the melting spray layer and the alloy substrate of the metal can be dissolved and diffused to form a metallurgical bonding similar to brazing. This process is called spray welding, and the resulting coating is called spray welding layer. This is the two methods of welding iron fence spray welding.

　　2、焊接

　　2. Welding

　　堆焊是利用焊接栏杆在铁翼护栏表面堆焊一层金属的过程。在机械制造业中，它是一种重要的、经济的制造和修理手段。铁艺护栏厂家表示，其目的是使零件表面获得耐磨、耐热、耐腐蚀等特殊性能的金属镀层，或恢复或增大零件的尺寸。济南铁翼护栏堆焊合金可归纳为铁基、镍基、钴基、铜基和碳化钨等多种类型。

　　Overlay welding is a process of overlaying a layer of metal on the surface of iron wing guardrail by welding handrail. In the machinery manufacturing industry, it is an important and economic means of manufacturing and repairing. The manufacturer of iron guardrail said that its purpose is to obtain metal coating with special properties such as wear resistance, heat resistance and corrosion resistance on the surface of parts, or to restore or increase the size of parts. The hardfacing alloy for Jinan Iron wing guardrail can be classified into iron base, nickel base, cobalt base, copper base, tungsten carbide and other types.

　　(1)镍基、钴基堆焊材料主要用于耐高温、耐磨损、耐腐蚀的场合。

　　(1) Nickel based and cobalt based hardfacing materials are mainly used in high temperature, wear-resistant and corrosion-resistant occasions.

　　(2)铁基堆焊合金的韧性与耐磨性匹配良好，能满足多种不同的要求，铸铁框架，且较低，色度高，品种也多，因此得到了广泛的应用。

　　(2) The toughness and wear resistance of Fe based hardfacing alloy match well, which can meet many different requirements. The cast iron frame has low price, high chroma and many varieties, so it has been widely used.

　　(3)碳化钨堆焊材料高，主要用于磨料磨损严重的工件。

　　(3) Tungsten carbide hardfacing materials have a high price and are mainly used for workpieces with severe abrasive wear.

　　目前，堆焊已广泛应用于轧辊、轮辋、曲轴、刀具、模具表面的强化和修补、不锈钢门头等。在模具边缘堆焊、铁扶手、热锻模、热剪模边缘堆焊中一般堆焊钴基合金、冷剪模边缘堆焊镍基合金，效果非常明显。

　　At present, overlay welding has been widely used in strengthening and repairing of roller, rim, crankshaft, cutter, die surface, stainless steel door head, etc. Generally, cobalt base alloy and nickel base alloy are overlaid on the edge of die, iron handrail, hot forging die and hot shearing die.

　　如果采用堆焊工艺制造热模具，可以选择韧性好的。Tieye护栏制造商展示了低的钢基体，堆焊钴基合金的工作部分的模具(如切削刃)。这就是铁栅栏的焊接方法——堆焊。

　　If the hardfacing process is used to make the hot die, the one with good toughness can be selected. Tieye guardrail manufacturers have demonstrated low-cost steel based, hardfacing cobalt based alloy for working parts of molds (such as cutting edges). This is the welding method of iron fence - hardfacing.
