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、噴焊

　　1. Spray welding

　　噴焊是利用熱源將金屬或非金屬材料加熱到熔化或半熔化狀態(tài),用高速氣流(噴槍)將被吹成小顆粒(霧化),和噴霧鐵藝護欄的表面,形成一個堅實的涂層表面處理方法。

　　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.

　　這種方法可以使鐵藝護欄的表面獲得各種不同硬度、耐磨性、耐腐蝕性、抗氧化性、潤滑性等特殊的物理化學性能。許多材料(金屬、陶瓷、塑料、水泥、石膏、木材等)可以噴涂在表面。

　　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.

　　為了提高噴層和基材之間的結(jié)合強度,降低涂層的孔隙率,熱源可用于熱噴涂層融化,因此熔噴層和金屬的合金基材可以溶解和擴散,形成冶金結(jié)合類似于釬焊。這種工藝稱為噴焊，由此得到的涂層稱為噴焊層。這是鐵柵欄焊接的兩種方法——噴焊。

　　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

　　堆焊是利用焊接欄桿在鐵翼護欄表面堆焊一層金屬的過程。在機械制造業(yè)中，它是一種重要的、經(jīng)濟的制造和修理手段。鐵藝護欄廠家表示，其目的是使零件表面獲得耐磨、耐熱、耐腐蝕等特殊性能的金屬鍍層，或恢復或增大零件的尺寸。濟南鐵翼護欄堆焊合金可歸納為鐵基、鎳基、鈷基、銅基和碳化鎢等多種類型。

　　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)鎳基、鈷基堆焊材料主要用于耐高溫、耐磨損、耐腐蝕的場合。

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

　　(2)鐵基堆焊合金的韌性與耐磨性匹配良好，能滿足多種不同的要求，鑄鐵框架，且價格較低，色度高，品種也多，因此得到了廣泛的應用。

　　(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)碳化鎢堆焊材料價格高，主要用于磨料磨損嚴重的工件。

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

　　目前，堆焊已廣泛應用于軋輥、輪輞、曲軸、刀具、模具表面的強化和修補、不銹鋼門頭等。在模具邊緣堆焊、鐵扶手、熱鍛模、熱剪模邊緣堆焊中一般堆焊鈷基合金、冷剪模邊緣堆焊鎳基合金，效果非常明顯。

　　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.

　　如果采用堆焊工藝制造熱模具，可以選擇韌性好的。Tieye護欄制造商展示了低價格的鋼基體，堆焊鈷基合金的工作部分的模具(如切削刃)。這就是鐵柵欄的焊接方法——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.
