手工(gong)焊(han)接、金屬極氣(qi)體保護焊(han)和鎢(wu)極惰性(xing)氣(qi)體保護焊(han)是焊(han)接不銹鋼通風管(guan)道加工(gong)的(de)常用方法。手工(gong)焊(han)接應(ying)用廣泛(fan)，操作簡單，主要(yao)由人調節。焊(han)縫填充材(cai)料(liao)為電焊(han)條。幾乎(hu)所(suo)有(you)的(de)材(cai)料(liao)都可以(yi)手工(gong)焊(han)接，即使在(zai)室(shi)外也可以(yi)，所(suo)以(yi)適(shi)應(ying)性(xing)很(hen)好。一(yi)般焊(han)接采(cai)用DC電。

　　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(han)條可以是(shi)鈦焊(han)條，也可以是(shi)閉合的。鈦焊(han)條易(yi)(yi)于(yu)焊(han)接，焊(han)縫美觀，焊(han)渣易(yi)(yi)于(yu)去除。但缺點是(shi)如果長時(shi)間不使用，必須重新烘烤(kao)，防(fang)止水分堆積。

　　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.

　　不銹鋼(gang)螺旋(xuan)風(feng)管的金屬(shu)(shu)極(ji)氣保護(hu)焊是一種氣體(ti)保護(hu)焊，也是一種電弧焊，焊條在保護(hu)氣體(ti)下(xia)通(tong)過電弧熔化(hua)。金屬(shu)(shu)極(ji)氣保護(hu)焊可(ke)用于鋼(gang)、非合金鋼(gang)、低合金鋼(gang)、高合金等材料(liao)，應用廣泛。

　　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(shi)有一點，它的(de)保(bao)護(hu)氣(qi)體(ti)(ti)必須是(shi)活性氣(qi)體(ti)(ti)，如二氧化碳或混合氣(qi)體(ti)(ti)。其(qi)缺點是(shi)如果焊接在室外，不銹鋼(gang)螺旋(xuan)風管不能受潮(chao)，否則會影響保(bao)護(hu)氣(qi)體(ti)(ti)的(de)保(bao)護(hu)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.

　　鎢(wu)極惰(duo)性氣(qi)體保護(hu)焊接電(dian)(dian)(dian)弧產生(sheng)于(yu)鎢(wu)焊絲(si)和工(gong)件之(zhi)間，因(yin)此(ci)要求保護(hu)氣(qi)體為(wei)純氬氣(qi)，焊絲(si)無電(dian)(dian)(dian)，因(yin)此(ci)可以手動送(song)(song)入，也可以機器送(song)(song)入，有時也可以不送(song)(song)入。那么它是(shi)用DC還是(shi)交流電(dian)(dian)(dian)，就(jiu)看(kan)焊接材(cai)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.

　　鎢極惰性氣(qi)體(ti)保護(hu)焊主要(yao)用于焊接(jie)薄、中(zhong)厚(hou)工(gong)件，材料范圍廣(guang)，包括(kuo)合金鋼(gang)、鋁(lv)、鎂、銅、灰(hui)鑄鐵、鎳、銀、鈦、鉛等(deng)。

　　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.
