現(xiàn)在應用焊接的企業(yè)大多數(shù)都在使用焊接機器人進行焊接產品，使用機器人焊接不僅可以提高工作效率及產品焊接品質，也減少了氣體煙塵弧光對工人的危害等許多優(yōu)點，是焊接產業(yè)走向自動化過程中一個必不可少的過程。

Nowadays, most enterprises that apply welding are using welding robots to weld products. Using robots for welding not only improves work efficiency and product welding quality, but also reduces the harm of gas smoke and arc light to workers. It is an essential process in the automation process of the welding industry.

大多數(shù)的機器人焊接也是氣體保護焊接，需要一種氣體對焊接處進行保護隔離，防止焊接處氧化造成焊接不良。常見的焊接方法有CO2氣體保護焊、MAG和MIG焊。CO2氣體保護焊就是以99%以上的二氧化碳氣體作為保護氣體的焊接方法；MAG是80%的隋性氣體（氬氣或氦氣）+20%的二氧化碳氣體作為保護按氣體來焊接的方法；MIG是以99.9%的隋性氣體（氬氣或氦氣）作為保護氣體焊接的方法。

Most robot welding is also gas shielded welding, which requires a gas to protect and isolate the welding area to prevent oxidation and welding defects. Common welding methods include CO2 gas shielded welding, MAG and MIG welding. CO2 gas shielded welding is a welding method that uses over 99% carbon dioxide gas as the shielding gas; MAG is a welding method that uses 80% inert gas (argon or helium) and 20% carbon dioxide gas as protective gas; MIG is a welding method that uses 99.9% inert gas (argon or helium) as a shielding gas.

MIG主要應用在鋁、銅等的有色金屬焊接中，CO2焊接是焊接應用中使用多的焊接方法，具有強度高、成本低的特點。但缺點是焊接時飛濺太多，焊渣不易清理。而使用MAG焊，即能保證焊接強度，外觀成形好，焊渣少。是近幾年在FANUC焊接機器人應用中使用為廣泛的一種焊接方法。

MIG is mainly used in the welding of non-ferrous metals such as aluminum and copper, and CO2 welding is the most commonly used welding method in welding applications, with the characteristics of high strength and low cost. But the disadvantage is that there is too much spatter during welding, and the welding slag is difficult to clean. Using MAG welding can ensure welding strength, good appearance, and less welding slag. It is the most widely used welding method in the application of FANUC welding robots in recent years.
