Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal (s), which heats the workpiece metal (s), causing them to fuse (melt and join).

熔化极气体保护电弧焊（英文简称gmaw）是采用连续等速送进可熔化的焊丝与被焊工件之间的电弧作为热源来熔化焊丝和母材金属，形成熔池和焊缝的焊接方法。

2024年1月22日 · Gas metal arc welding (“GMAW”) is an arc welding process that uses a consumable wire electrode and shielding gas, which a welding gun feeds to the joint. An electrical arc between the wire and base metal generates heat that melts.

2019年12月14日 · GMAW的主要优势在于每小时的金属熔敷量，这极大地降低了劳动力成本。 气体保护焊的另一个优势在于它是一种干净的工艺，这主要归功于没有使用焊剂。 在通风不良的车间会发现，从手工电弧焊或药芯焊换成气体保护焊后情况会得到改善，这是因为烟的产生减少了。 由于有各种各样的焊丝可选用，而且焊接设备变的更便于携带，气体保护焊的适用领域不断得到扩展。 该工艺的另外一个优点是可见性。 因为没有焊渣，焊工能够很容易地观察电弧和熔池的情 …

Gas metal arc welding (GMAW) processes such as metal inert gas (MIG) and metal active gas (MAG) are the most frequently used arc welding technologies worldwide. The choice of welding gas has a big impact on the result of these welding jobs.

The GMAW process is probably the most commonly used gas-shielded arc welding process for metals. Depending on the shielding gas used, a distinction is made between MIG (metal inert gas) and MAG (metal active gas).

Gas metal arc welding (GMAW) is performed by using direct current reverse polarity as it gives both good cleaning action and fast filler metal deposition rates. A rather high welding current is desirable as these extra current breaks up the globules of molten metal into a fine spray.

利用气体作为保护介质的电弧焊。 它包括 钨极惰性气体保护焊 (TIG)和 熔化极气体保护焊 (GMAW)。 两者的差别在于所用的电极不同，前者用的是非熔化电极—钨棒，后者用的是熔化电极—焊丝。 气体保护电弧焊是在 第二次世界大战 期间发展起来的。 在飞机制造业中，为适应铝合金、镁合金、不锈钢等焊接的需要，钨极惰性气体保护焊首先问世。 [1] 气体保护电弧焊机主要分手工、半自动和自动三类。 手工焊机只用于钨极惰性气体保护焊，由弧焊电源、焊接电缆、气 …

2023年5月24日 · Gas metal arc welding (GMAW/MIG), also known as wire welding, is a commonly used welding process. It is a process that forms an electric arc between the metal and the wire electrode to transmit heat to the metal pieces, and the parts achieve a bond permanently through melting and fusing.

As you read on, keep in mind that your recollection for FCAW will serve as a good reference for the equipment, setup, and welding techniques used in GMAW. Let’s break down the GMAW setup into its major components: Shielding gas; Power source capable of delivering a direct current (DC) at a constant voltage; Wire feeder; Welding gun
