如果您需要決定哪種類型weldingto choose for your next project – or if you are trying to figure out which technique you should start learning – you came to the right place.
Below, I’ll take a look at the three most common welding methods – MIG, TIG, and stick – to see how they compare against each other.
MIG, TIG & Stick Welding: The Basics
At a most basic level, welding is passing a current through an electrode and melting a filler material into a groove or area to seal it so that two pieces of metal become one. There are over 30 types of welding, but, in this article, we’ll focus on the most common three.
TIG is Tungsten Inert Gas and is actually GTAW Gas Tungsten Arc Welding. Stick welding is SMAW, Shielded Metal Arc Welding. The technical names are generally only used by inspectors and officials.
MIG焊接
氣金屬弧焊（GMAW） - 俗稱金屬惰性氣體（MIG）焊接 - 是最廣泛使用的方法之一，其原因是好的。
It is easier to perform than others. Not only is the electrode continuously fed through the gun but there is little to no electrode sticking. The inert gas used in MIG welding protects the weld pool from contaminants in the atmosphere.
TIG焊接
Gas tungsten arc welding (GTAW) – commonly known as tungsten inert gas (TIG) welding is a great option for smaller, usually thinner projects that require a higher level of cleanliness and control.
通過在一隻手中握住加熱火炬並在另一方麵填充金屬來完成TIG焊接。通常由氬氣屏蔽，TIG使用鎢將電流輸送到焊接弧。
Stick Welding
屏蔽金屬弧焊（SMAW） - 通常稱為粘焊 - 通過通過塗覆在粉末通量塗覆的消耗電極發送電流來完成。
As the current travels through the electrode making contact with the piece being welded, the electrode metal is superheated and fills the gap or area between pieces. This method yields very strong welds.
mig與tig與鋼焊接：他們的差異是什麼？
In terms of ease of use, nothing beats stick.
It’s rugged enough to use on dirty or painted surfaces and it’s great for a beginner who doesn’t know how to weld. MIG is trickier for most newcomers to welding because the shielding gas needs to be aimed properly to protect the weld and the stick out of the electrode must be maintained manually. TIG welding has a technique that is an art form on its own.
For speed, it’s really a toss-up between MIG and stick. TIG is a technique that has its place but it’s slow. Not only is the process more meticulous, but the actual pre- and post-clean can also take some time as well. Stick is fast because you can go right through any kind of contamination or impurity – because of the high heat, it will probably cook right off. MIG is equally fast, though not as forgiving of impurities. That said, in ideal conditions, MIG welding would be as fast as stick welding.
TIG is easily the most expensive of all the three methods. The gas, gun and filler metal along with the special tungsten rods are pricier than the other two methods. Not to mention the fact that you have to have a grinder or belt sander to shape the tungsten. MIG is the second most pricey due to the use of gas. Stick is fairly inexpensive. The only real cost for stick welding is the cost of the machine as electrodes are relatively inexpensive.
All three methods require safety gear but TIG can be used slightly more casually due to its lower heat output.
您應該選擇哪種焊接方法？
If you are doing a basic repair of a gate or fusing together two metal parts for your bumper, stick would probably be the way to go. It’s easy and inexpensive. The welds are incredibly strong and you don’t need to worry about any complicated preparation or finishing work.
由於其簡單性，大多數人學會了先用棍子焊接。在嚐試焊接整個空隙和開口之前，我建議在重複上獲取一塊廢料並重複粘在一起。沒有什麼比認為你會撞到珠子並陷入困惑的了。用棍子的一個缺點是初學者將有一個艱難的時間使焊縫看起來很好。建議使用某種防濺物。
如果您需要修複金屬店椅或修補一塊草坪設備，MIG是一個偉大的選擇。它也很幹淨，但並不像粘焊一樣粗糙。如果您有內部項目或任務，MIG將是一個很好的選擇。
在學習MIG時，我建議從較厚的規格廢料件開始並嚐試不同的模式。圈子，s和三角形都產生不同的焊接。從MIG開始的最大缺點是學習如何配置電線速度和電壓。
TIG really is beautiful and the welds it produces are clean and strong. The welds can be just as strong as the other two methods. TIG is amazing for very thin, very fine material. It’s also incredibly clean to weld with.
如果你決定to start with TIG welding, use the ”walking the cup” technique. Use the edge of the torch ”cup” and walk it like you would walk a fridge. The welds from TIG are technical and organized. It is, however, not a quick technique to pick up.
概括
到目前為止，最簡單的方法可以粘貼焊接。這不僅是因為它很容易表現，而且因為需要更少的準備。換句話說，用粘焊，你不必擔心你在開始焊接之前的兩種材料的條件。
On the other hand, if you want something more challenging – but at the same time artisan – go for TIG welding. It will take you longer to learn and even longer to master, but it will be a very fulfilling endeavor.
