专注通风管道加工·排烟罩

　　手工焊接、金属极气体保护焊和钨极惰性气体保护焊是焊接不锈钢通风管道加工的常用方法。手工焊接应用广泛，操作简单，主要由人调节。焊缝填充材料为电焊条。几乎所有的材料都可以手工焊接，即使在室外也可以，所以适应性很好。一般焊接采用DC电。

　　Manual welding, metal inert gas welding, and tungsten inert gas welding are commonly used methods for welding stainless steel ventilation ducts. Manual welding is widely used, easy to operate, and mainly adjusted by humans. The filler material for the weld seam is welding electrode. Almost all materials can be manually welded, even outdoors, so they have good adaptability. Generally, DC electricity is used for welding.

　　焊条可以是钛焊条，也可以是闭合的。钛焊条易于焊接，焊缝美观，焊渣易于去除。但缺点是如果长时间不使用，必须重新烘烤，防止水分堆积。

　　The welding rod can be a titanium welding rod or a closed one. Titanium welding rods are easy to weld, with beautiful welds and easy removal of welding slag. But the disadvantage is that if not used for a long time, it must be re baked to prevent moisture accumulation.

　　不锈钢螺旋风管的金属极气保护焊是一种气体保护焊，也是一种电弧焊，焊条在保护气体下通过电弧熔化。金属极气保护焊可用于钢、非合金钢、低合金钢、高合金等材料，应用广泛。

　　Metal electrode gas shielded welding of stainless steel spiral ducts is a type of gas shielded welding and arc welding, in which the welding rod is melted by an arc under shielding gas. Metal electrode gas shielded welding can be used for materials such as steel, non alloy steel, low-alloy steel, and high alloy, and is widely used.

　　但是有一点，它的保护气体必须是活性气体，如二氧化碳或混合气体。其缺点是如果焊接在室外，不锈钢螺旋风管不能受潮，否则会影响保护气体的保护效果。

　　But one thing, its protective gas must be an active gas, such as carbon dioxide or a mixture of gases. The disadvantage is that if welded outdoors, the stainless steel spiral air duct cannot be dampened, otherwise it will affect the protective effect of the protective gas.

　　钨极惰性气体保护焊接电弧产生于钨焊丝和工件之间，因此要求保护气体为纯氩气，焊丝无电，因此可以手动送入，也可以机器送入，有时也可以不送入。那么它是用DC还是交流电，就看焊接材料了。

　　The tungsten inert gas shielded welding arc is generated between the tungsten welding wire and the workpiece, so pure argon gas is required as the shielding gas. The welding wire has no electricity, so it can be manually fed, machine fed, or sometimes not fed. So whether it uses DC or AC depends on the welding material.

　　钨极惰性气体保护焊主要用于焊接薄、中厚工件，材料范围广，包括合金钢、铝、镁、铜、灰铸铁、镍、银、钛、铅等。

　　Tungsten inert gas shielded welding is mainly used for welding thin and medium thick workpieces, with a wide range of materials including alloy steel, aluminum, magnesium, copper, gray cast iron, nickel, silver, titanium, lead, etc.
