What are the abbreviations for different welding processes?
Here are some of the standard abbreviations for different welding processes, what they stand for, and common equivalent terms. SMAW = Shielded Metal Arc Welding = 'Stick' welding (also called MMA for manual metal arc in Europe I believe)
What is welder’s Flash?
Welder’s flash refers to this condition when it is caused by UV rays from a welding torch. It can feel like having a “sunburn” on the eyes. Photokeratitis is also often called arc eye, flash burn, ultraviolet keratitis and snow blindness .
What does OFW stand for in welding?
OFW = Oxygen Fuel Welding - includes oxy-acetalyne as well as other fuel gasses = sometimes called 'Gas Welding' These first four are the ones most likely to be seen and used outside of specialized welding facilities. SAW = Submerged Arc Welding, often shorted to sub-arc.
How long after UV exposure do symptoms of welder’s Flash appear?
Symptoms of welder’s flash can show up as early as 30 minutes after UV exposure. However, it can take up to 12 hours for welder’s flash symptoms to occur. The most common symptom of welder’s flash is intense pain in the affected eye. You may have pain in both eyes if each was damaged by UV rays.

What is TIG and SMAW?
Shielded metal arc welding (SMAW) and tungsten inert gas (TIG) are two of the most common and widely used welding processes today. They both rely on the use of heat to melt and join multiple metal or thermoplastic objects. When the metal objects cool, they harden and fuse together.
What are the 4 basic weld types?
The four main types of welding are: Gas Metal Arc Welding (GMAW/MIG), Gas Tungsten Arc Welding (GTAW/TIG), Shielded Metal Arc Welding (SMAW), and Flux Cored Arc Welding (FCAW).
Is TIG the same as arc?
Tungsten inert gas (TIG) is also referred to as gas tungsten arc welding (GTAW). Both TIG and arc welding are electric arc welding techniques that use an inert gas, typically argon or helium, around the weld joint to prevent oxidation. The main difference between the two relates to the electrode.
What SMAW means?
Manual metal arc welding (MMA or MMAW), also known as shielded metal arc welding (SMAW), flux shielded arc welding or stick welding, is a process where the arc is struck between an electrode flux coated metal rod and the work piece. Both the rod and the surface of the work piece melt to create a weld.
What is the strongest weld?
TIG weldingTIG welding is often considered the strongest weld since it produces extreme heat, and the slow cooling rate results in high tensile strength and ductility. MIG is also an excellent candidate for the strongest type of weld because it can create a strong joint.
What is the hardest metal to weld?
By weight, good aluminum alloys can be stronger than common titanium alloys. What kind of metal is the most difficult to weld? Titanium is probably the most difficult. It has to be surrounded by an inert gas like argon.
What is the easiest welding to learn?
MIG Welding (Beginner) MIG welders are among the best type for beginners, as they're designed with a wire welding electrode on a spool that is fed at a pre-selected speed through a welding gun. As a semi-automatic or automatic process, gas metal arc welding (GMAW or MIG), is the easiest to learn.
What are the 7 basic types of welding?
These include metal inert gas (MIG) welding, stick welding, tungsten inert gas (TIG) welding also know as gas tungsten arc welding (GTAW), gas welding, metal active gas (MAG) welding, flux cored arc welding (FCAW), gas metal arc welding (GMAW), submerged arc welding (SAW), shielded metal arc welding (SMAW) and plasma ...
Is TIG stronger than MIG?
TIG welds also go much deeper in penetration than MIG welds, making them much harder to pull apart. You can form small, strong tacks with a TIG welder without any filler wire, and you will struggle to break them apart. Small MIG tacks break easily.
Which is better SMAW or MIG?
QUALITY and QUANTITY. Both MIG and Stick welding systems can produce high-quality welds, but the type of metal makes a big difference in which machine works better. For thinner metals, MIG welding is the better choice for creating a clean, strong joint. On thicker metals — over ⅜ inch — the Stick has better performance ...
What is better SMAW or GMAW?
Efficiency. SMAW and GMAW both utilize quite basic techniques, meaning that even less experienced welders can usually get good results from these welding styles. Yet when it comes to laying down welds as quickly and efficiently as possible, GMAW comes out the clear winner.
What does MMA stand for in welding?
Stick welding, also known as manual metal arc (MMA) welding refers to a welding method where a filler rod in the electrode holder serves as the welding electrode. The arc burns between the rod and the workpiece.
What is the 5 basic of welding?
The five basic weld joints include the butt joint, the lap joint, the tee joint, the corner joint, and the edge joint. The butt joint occurs when two members are placed side-by-side or butted together.
What are the 7 basic types of welding?
These include metal inert gas (MIG) welding, stick welding, tungsten inert gas (TIG) welding also know as gas tungsten arc welding (GTAW), gas welding, metal active gas (MAG) welding, flux cored arc welding (FCAW), gas metal arc welding (GMAW), submerged arc welding (SAW), shielded metal arc welding (SMAW) and plasma ...
What are the 4 most common welding rods?
Common electrodes used in Stick welding are 6010, 6011, 6013, 7018 and 7024 with the most common diameters ranging from 1/8- to 5/32-in. Each of these electrodes offers all-position welding capabilities (except 7024).
What are the 3 types of weld?
Three of the most common are Arc, MIG (Metal, Inert Gas) or GMAW (Gas, Metal Arc Welding), and TIG (Tungsten Inert Gas) welding. In order to know which process is best for the particular job you're working on, here's what you should know about each of them. Arc welding is the oldest of these three welding processes.
How to Treat Welder's Flash | Healthfully
Place an eye patch over your affected eye to protect it during sleep. Take a dry gauze pad and fold it into a square, and place that over your eye.

What if I think I have welder’s flash?
If you have symptoms of welder’s flash, make an appointment with your eye doctor. The doctor can properly diagnose welder’s flash or a different eye condition that could be causing your symptoms.
How long does it take for a welder's flash to show?
Symptoms of welder’s flash can show up as early as 30 minutes after UV exposure. However, it can take up to 12 hours for welder’s flash symptoms to occur.
What happens if you weld with arc eyes?
Like the name implies, welders are at risk for photokeratitis when their eyes are exposed to bright flashes or “arcs” of UV radiation while welding. This type of corneal welding injury is also known as “ arc eye ” and “flash burn.”
What to wear when welding?
If you’re a welder, wear a protective welding helmet or filter glasses while welding to guard against arc UV light. If you work in a lab or another occupation that could expose you to eye-damaging UV rays, wear proper protective eyewear, glasses or face shields.
Can you get photokeratitis if you are not a welder?
Even if you’re not a welder, your eyes are vulnerable to photokeratitis in a variety of situations, including:
Can welders get photokeratitis?
But photokeratitis doesn’t affect welders alone. For example, your eyes are at risk in bright, outdoor settings like snow or water if you’re not wearing protective sunglasses. Your eyes are also at risk in some indoor settings when there are certain types of broken high-intensity light bulbs.
What does GTAW mean in welding?
GTAW = Gas Tungsten Arc Welding = 'TIG' (Tungsten Inert Gas) = older slang term 'Heliarc welding'.
