Types of Welding

You can find multiple names used for precisely the same process in welding given that they have become commonly accepted slang terms. Regardless of everything you call it, so long as you understand these are same. Permit me to explain.

Stick welding can be a slang term for “Shielded Metal Arc Welding” and is commonly abbreviated, or known as, as “SMAW”. The slang term arises from the rod utilized because it’s appears to be a stick. This can be a method that utilizes a automobiles which causes constant amperage to produce an arc. Such a welder utilizes a rod, or electrode, made of metal with a flux coating on the outside of that protects the weld area from your air as the rod is burning. SMAW is usually utilized in the area since it is an operating welding process that is cheap, is very rewarding of many metals, and provides for welding thick materials. This makes it an excellent joining process for many industrial construction needs. SMAW is additionally the most basic form of welding that is certainly taught inside the most of schools as foundation to learning other kinds of metal joining processes.

TIG welding, or TIG, is definitely an abbreviation for “Tungsten Inert Gas” however its proper name is “Gas Tungsten Arc Welding” commonly abbreviated and called “GTAW”. In older times, prior versions be also referred to as “HeliArc”. GTAW is really a joining technology that utilizes a consistent current power source much like Stick welding. What changes may be the way filler metal is deposited in the joint. TIG runs on the torch that has a bit of tungsten to create an arc. The torch also offers shielding gas flowing through it to safeguard the weld area from air. Characteristics of tungsten allow arc temperatures to arrive at more than 10,000 degrees. Just how TIG works is that the arc is created as well as a filler metal is included with the joint. Filler metals for this process appear in wire form and so are simply cut to length. Probably the most frequently used shielding gas is Argon, that is utilized for welding a lot more than 90 percent of metals. TIG welding is employed for welding exotic metals or anywhere that requires excellent welds. This technique is one of the hardest kinds of welding to master.

MIG welding, or MIG, is an abbreviation for “Metal Inert Gas” which can be more formally known as “Gas Metal Arc Welding” or “GMAW”. The definition of MIG emanates from the main shielding gasses used which were the inert, or Nobel, gasses. Today the gases used vary, hence the name has officially been changed to “Gas Metal Arc Welding”. MIG welding could be the slang term that’s commonly accepted. Additionally it is called “Wire Wheel Welding”. This process works on the wire feed to move solid filler wire to the weld joint. The wire feed is connected to a relentless voltage power that creates the arc to melt the wire if this hits the weld joint. Prior to the wire creates an arc there needs to be a shielding gas feed from the system. MIG welding is completed by way of a MIG gun that mixes the wire, electricity and shielding gasses all at the same time. The MIG gun carries a trigger that, once squeezed, starts the metal joining process. This process is considered semi-automatic as the filler metal is continuously feed on the weld joint. This metal joining process is usually utilized in factories where high production is necessary. MIG is not hard to operate but starting the equipment could be troublesome for the less experienced operator.

FCAW, or “Flux Cored Arc Welding”, is technically considered quantity welding process. The reality is that FCAW is really a different kind of electrode or filler wire used in a MIG welding machine. The electrode is a hollow tube that has flux within the center. What this does is permit the electrode to weld without the need for an outside shielding gas. There are two types of electrodes found in FCAW; self shielding and dual shielding. Self is an electrode it doesn’t need any shielding gas. It is rather comparable to a Stick welding electrode turned back to front. What this will is allow welding in windy conditions. The down side to this of MIG welding is the fact that wind or drafts cause welding defects. A self shielding FCAW electrode solves that problem. Dual shielding electrodes need shielding gas to function properly. The advantage of this kind of electrode will be the quantity of weld it could deposit. FCAW is typically used in shipyards or anywhere that really needs lots of welding to be done on thick metals.

There are numerous more different kinds of welding which might be used. Examples include:

Oxy Acetylene
SAW or “Submerged Arc Welding”
Electron Beam
Ultra Sonic
And also the list proceeds! Ultimately probably the most commonly used processes are Stick, TIG, MIG and FCAW. Fundamental essentials processes which are currently popular since they’re what industry needs. They produce welds starting from mass production to x-ray quality.
