Difference between MIG and TIG Welding
MIG 与 TIG焊不同点
we will discuss difference between MIG and TIG welding. These are two main types of welding. 我们将讨论MIG和TIG焊接之间的区别。这是两种主要的焊接类型。
The term MIG is stand for Metal inert Gas welding and TIG is stand for Tungsten Inert Gas welding. These are widely use for joining a verity of shapes and material. Today we will learn the main difference between them.
术语MIG代表金属惰性气体焊接,TIG代表钨极惰性气体焊接。这些广泛用于连接各种形状和材料。今天我们将了解它们之间的主要区别。
1 MIG Welding
MIG works on same principle of arc welding. It works on basic principle of heat generation due to electric arc. This heat is further used to melt consumable electrode and base plates metal which solidify together and makes a strong joint. The shielded gases are also supplied through nozzle which protect the weld zone from other reactive gases. This gives good surface finish and a stronger joint.
MIG的工作原理与TIG或弧焊相同。它的工作原理是电弧产生的热量。该热量进一步用于熔化自耗电极和基板金属,它们固化在一起并形成牢固的接合。屏蔽气体也通过喷嘴供应,喷嘴保护焊接区免受其他反应气体的影响。这样可以提供良好的表面光洁度和更强的接合
2 TIG Welding
TIG welding works on same principle of arc welding. In a TIG welding process, a high intense arc is produced between tungsten electrode and work piece. In this welding mostly work piece is connected to the positive terminal and electrode is connected to negative terminal. This arc produces heat energy which is further used to join metal plate by fusion welding. A shielding gas is also used which protect the weld surface from oxidization.
TIG焊接的工作原理与电弧焊相同。在TIG焊接过程中,在钨电极和工件之间产生高强度电弧。在这种焊接中,大部分工件连接到正极端子,电极连接到负极端子。该电弧产生热能,其进一步用于通过熔焊连接金属板。 还使用保护气体来保护焊接表面免受氧化。
