一、手工焊接

1、 Manual welding

手工焊是一種特別普遍的、常用的,同時也是操作簡單使用方便的焊接法。電弧的長度可以依靠操作者手工來進(jìn)行合理調(diào)節(jié),而調(diào)節(jié)則是根據(jù)電焊條和需要焊接的工件之間的縫隙來進(jìn)行,根據(jù)縫隙的大小調(diào)節(jié)電弧的長度。焊條不僅可以作為焊接不銹鋼材質(zhì)的工具,同時,它在一定的情況下也可以作為焊縫的一種有效填充材料。而這種材料,可以更好地接合不銹鋼工件,達(dá)到更好的兼容性。

Manual welding is a particularly common and commonly used welding method, which is also easy to operate and convenient to use. The length of the arc can be adjusted manually by the operator, and the adjustment is based on the gap between the welding electrode and the workpiece to be welded, and the length of the arc is adjusted according to the size of the gap. Welding rods can not only be used as tools for welding stainless steel materials, but also as an effective filler material for welds under certain circumstances. And this material can better bond stainless steel workpieces and achieve better compatibility.

二、金屬極氣體保護(hù)焊

2、 Metal electrode gas shielded welding

金屬氣體保護(hù)焊是一種自動氣體保護(hù)電弧焊。在使用此種方法的過程中,電弧在保護(hù)氣體約束下,在焊絲和不銹鋼工件之間進(jìn)行燃燒焊接。機(jī)械焊接設(shè)備送入的焊絲就是一根根焊條,通過電弧下融化為液體不銹鋼。鑒于MAG焊接法的通用性和特殊性兼有的特殊性能,是當(dāng)今不銹鋼焊接行業(yè)使用.為廣泛的一種焊接法。而且,因?yàn)槠渚邆涠囗?xiàng)優(yōu)點(diǎn),在很長一段時間內(nèi)也一定是廣泛的焊接方法。

Metal gas shielded welding is an automatic gas shielded arc welding. During the use of this method, the arc undergoes combustion welding between the welding wire and the stainless steel workpiece under the constraint of protective gas. The welding wires fed into the mechanical welding equipment are welding rods that melt into liquid stainless steel through an arc. Given the universality and specificity of MAG welding method, which has special properties, it is widely used in the stainless steel welding industry today. Moreover, due to its multiple advantages, it will definitely be a widely used welding method for a long time.

三、鎢極惰性氣體保護(hù)焊

3、 Tungsten inert gas shielded welding

在這種使用方法中,電弧產(chǎn)生在穩(wěn)定的鎢電焊絲和不銹鋼材質(zhì)工件,這種保護(hù)焊所采用的保護(hù)氣體為氬氣,自動焊接設(shè)備所送入的焊絲自身不帶電.焊絲也可以進(jìn)行人工送,但是有一定的危險(xiǎn)性。一些特定條件下,不需要送入焊絲,需要焊接的不銹鋼材料決定了是否采用直流電。如果采用直流電時,鎢電焊絲必須設(shè)置為負(fù)極,因?yàn)槠渥陨砗竿改芰Ψ浅?qiáng),對于各種種類的不銹鋼都有很好的焊接效果

In this usage method, the arc is generated on stable tungsten welding wires and stainless steel workpieces. The protective gas used for this type of welding is argon, and the welding wire fed by automatic welding equipment is not charged. The welding wire can also be manually fed, but there is a certain degree of danger. Under certain specific conditions, it is not necessary to feed welding wire, and the stainless steel material to be welded determines whether to use direct current. If direct current is used, tungsten welding wire must be set as the negative electrode because its own welding penetration ability is very strong, and it has good welding effects for various types of stainless steel
