一、手艺焊

1、 Craft welding

运用非常遍及，且操作简单，主要是靠人进行调整，焊缝填充资料为电焊条。手艺焊简直能焊接一切的资料，即便在室外也能够，因而它具有很好的适应性，一般焊接时是采用直流电。

It is widely used and easy to operate. It is mainly adjusted by people. The weld filling data is electrode. Craft welding can weld almost all materials, even outdoors, so it has good adaptability. Generally, DC is used for welding.

电焊条，既能够是钛型焊条，也能够是缄性的。钛型焊条比较简单焊接，焊缝漂亮，且焊渣简单去除。但缺陷是假如长时间不用后再运用，那么有必要从头进行烘烤，以防潮气积累。

The electrode can be either titanium electrode or sealed. Titanium electrode is relatively simple to weld, the weld is beautiful, and the welding slag is easy to remove. But the defect is that if it is not used for a long time, it is necessary to bake from the beginning to prevent moisture accumulation.

二、金属气体维护焊

2、 Metal gas maintenance welding

它归于气体维护焊，也是一种电弧焊，是在维护气体下，焊条被电弧融化。金属*气体维护焊可用于钢、非合金钢、低合金钢以及高合金等这些资料，运用很广泛。但有一点，它的维护气体有必要为活*气体，比如二氧化碳或许混合气体等。的缺陷是假如在室外进行焊接，那么工件不能受潮，否则会影响维护气体的维护效果。

It belongs to gas maintenance welding, which is also an electric arc welding. Under the maintenance gas, the welding rod is melted by the arc. Metal * gas maintenance welding can be used for steel, non alloy steel, low alloy steel and high alloy, which is widely used. But for one thing, its maintenance gas must be live * gas, such as carbon dioxide or mixed gas. The defect is that if welding is carried out outdoors, the workpiece cannot be affected by moisture, otherwise it will affect the maintenance effect of maintenance gas.

三、钨惰性气体维护焊

3、 Tungsten inert gas maintenance welding

电弧是在钨电焊丝和工件之间发生，所以要求维护气体为纯ya气，且焊丝是不带电的，所以既能够手动送入，也能够机器送入，有时也能够不送入。然后它到底是运用直流电仍是交流电，则取决于焊接资料。

The arc occurs between the tungsten electric welding wire and the workpiece, so the maintenance gas is required to be pure Ya gas, and the welding wire is not charged, so it can be fed manually, by machine, and sometimes not. Then whether it uses DC or AC depends on the welding data.

钨惰性气体维护焊主要是用于焊接薄和中等厚度的工件，原料的规模很广，包含合金钢、铝、镁、铜、灰口铸铁、镍、银、钛以及铅等。

Tungsten inert gas maintenance welding is mainly used for welding thin and medium thickness workpieces. The scale of raw materials is very wide, including alloy steel, aluminum, magnesium, copper, gray cast iron, nickel, silver, titanium and lead.
