            焊接方法根據對象和用途大致可分為建筑焊接結構、貯罐和容器焊接結構、管道焊接結構、導電性焊接結構四類,我們所稱的建筑鋼結構包含了這四類焊接結構。選用的結構材料是鋼材,而且大多為普通碳素鋼和低合金結構鋼,山東數控焊接設備的幾種焊接方法有手工電弧焊、氣體保護焊、自保護電弧焊、埋弧焊、螺柱焊、點焊等。

            Welding methods can be roughly divided into building welding structure, storage tank and container welding structure, pipeline welding structure and conductive welding structure according to the object and purpose. The building steel structure we call includes these four types of welding structures. The selected structural materials are steel, and most of them are ordinary carbon steel and low alloy structural steel. Several welding methods of Shandong CNC welding equipment include manual arc welding, gas shielded welding, self shielded arc welding, submerged arc welding, stud welding, spot welding, etc.
            手工電弧焊依靠電弧的熱量進行焊接的方法稱為電弧焊,手工電弧焊是用手工操作焊條進行焊接的一種電弧焊,是建筑鋼結構焊接中最常用的方法。
            Manual arc welding relies on the heat of the arc for welding, which is called arc welding. Manual arc welding is a kind of arc welding with manual welding rod. It is the most commonly used method in the welding of building steel structure.
            手工電弧焊的原理,如圖7—1所示,焊條和焊件就是兩個電極產生電弧,電弧產生大量的熱量,熔化焊條和焊件。焊條端部熔化形成熔滴,過渡到熔化的焊件的母材上融合,形成熔池并進行一系列復雜的物理——冶金反應。隨著電弧的移動,液態熔池逐步冷卻、結晶,形成焊縫。
            The principle of manual arc welding is shown in Figure 7-1. The electrode and weldment are two electrodes that generate an arc. The arc generates a lot of heat to melt the electrode and weldment. The end of the electrode melts to form droplets, which are transferred to the base metal of the molten weldment to form a molten pool and carry out a series of complex physical metallurgical reactions. With the movement of the arc, the liquid molten pool gradually cools and crystallizes to form a weld.
            在高溫作用下,冷敷于電焊條鋼芯上的藥皮熔融成溶渣,覆蓋在熔池金屬表面 ,它不僅能保護高溫的熔池金屬不與空氣中有害的氧、氮發生化學反應,并且還能參與熔池的化學反應和滲入合金等,在冷卻凝固的金屬表面,形成保護渣殼。
            Under the action of high temperature, the coating cold deposited on the steel core of the welding strip melts into molten slag and covers the metal surface of the molten pool. It can not only protect the high-temperature molten pool metal from chemical reaction with harmful oxygen and nitrogen in the air, but also participate in the chemical reaction of the molten pool and infiltrate the alloy, forming a protective slag shell on the cooled and solidified metal surface.
            窄間隙焊接本方法是利用已有的氣體保護焊的特別技術,具有焊接接頭的坡口截面面積比手工電弧焊或氣體保護焊的坡口截面面積小,這是本方法的特點 。
            Narrow gap welding this method uses the existing special technology of gas shielded welding, and has the characteristics that the groove section area of the welded joint is smaller than that of manual arc welding or gas shielded welding.

            窄間隙焊接可以在平焊、橫焊和立焊位置進行,橫焊適合工程現場的柱接頭,平焊和立焊分別適合于工廠內箱形柱的角接頭和柱與梁的焊接。
            Narrow gap welding can be carried out at the positions of flat welding, horizontal welding and vertical welding. The horizontal welding is suitable for the column joints on the project site. The flat welding and vertical welding are respectively suitable for the corner joints of box columns and the welding of columns and beams in the factory.
            螺柱焊接是在螺柱與母材之間通以焊接電流,使相互接觸的局部加熱并接合的方法,主要用于抗剪連接件及混凝土錨栓等的焊接,另外還廣泛用于安裝隔熱材料和隔音材料的連接件。
            Stud welding is a method of heating and joining the local parts in contact with each other by applying welding current between the stud and the base metal. It is mainly used for the welding of shear connectors and concrete anchor bolts. In addition, it is also widely used for the installation of connectors of heat insulation materials and sound insulation materials.
