Common welding processes

焊接是我們生活中應(yīng)用很廣泛的工藝，不管是維修還是一些金屬鑄件可能都會進行焊接。機電行業(yè)大家是很熟悉的，焊接更是機電領(lǐng)域不可缺少的一項技術(shù)。以前進行焊接我們可能都只是使用焊槍，然后應(yīng)用原始的焊接方法。隨著社會的不斷發(fā)展，焊接方法也有不斷的改變，儲能螺柱焊機這些焊接設(shè)備也都投入到了市場使用。可能很多人多于焊接方法都不是很了解，下面我們就來了解下常見的焊接工藝--手弧焊。

Welding is a widely used process in our life. It may be used for maintenance or some metal castings. We are familiar with the electromechanical industry, and welding is an indispensable technology in the electromechanical field. In the past, we may only use the welding gun and then apply the original welding method. With the continuous development of society, the welding methods are also changing. The welding equipment such as energy storage stud welder has also been put into use in the market. Many people may not know much about welding methods. Let's learn about the common welding process - manual arc welding.

手弧焊是各種電弧焊方法中發(fā)展比較早的，目前仍然應(yīng)用比較廣的一種焊接方法。它是以外部涂有涂料的焊條作填充金屬，電弧是在焊條的端部和被焊工件表面之間燃燒。涂料在電弧熱作用下一方面可以產(chǎn)生氣體以保護電弧，另一方面可以產(chǎn)生熔渣覆蓋在熔池表面，防止熔化金屬與周圍氣體的相互作用。熔渣的更重要作用是與熔化金屬產(chǎn)生物理化學(xué)反應(yīng)或添加合金元素，改良焊縫金屬性能。手弧焊設(shè)備簡單、輕便，操作靈活。可以應(yīng)用于維修及裝配中的短縫的焊接，特別是可以用于難以達到的部位的焊接。手弧焊配用相應(yīng)的焊條可適用于大多數(shù)工業(yè)用碳鋼、不銹鋼、鑄鐵、銅、鋁、鎳及其合金。

Manual arc welding is a kind of welding method which developed earlier and is still widely used at present. The welding rod coated on the outside is used as the filler metal, and the arc burns between the end of the welding rod and the surface of the workpiece to be welded. Under the action of arc heat, on the one hand, the coating can produce gas to protect the arc, on the other hand, it can produce slag to cover the surface of the molten pool to prevent the interaction between the molten metal and the surrounding gas. The more important role of slag is to produce physical and chemical reaction with molten metal or add alloy elements to improve the properties of weld metal. Manual arc welding equipment is simple, light and flexible. It can be applied to the welding of short joints in maintenance and assembly, especially for the welding of parts that are difficult to reach. Manual arc welding with corresponding electrodes can be applied to most industrial carbon steel, stainless steel, cast iron, copper, aluminum, nickel and their alloys.

關(guān)于手弧焊這一焊接工藝的內(nèi)容小編就介紹到這里了，希望能夠?qū)Υ蠹矣兴鶐椭?。不過小編也要提醒大家一下在進行焊接工作的時候要注意做好防護措施，以免傷到自己。另外，焊接設(shè)備也要定期的維護保養(yǎng)，這樣能夠延長它們的使用壽命。

The content of manual arc welding is introduced here. I hope it can be helpful to you. However, Xiaobian should also remind you to take protective measures when welding to avoid hurting yourself. In addition, welding equipment should also be maintained regularly, which can prolong their service life.
