A welder is a person or equipment that fuses materials together. The term welder refers to the operator, the machine is referred to as the welding power supply. The materials to be joined can be metals (such as steel, aluminum, brass, stainless steel etc.) or varieties of plastic or polymer. Welders typically have to have good dexterity and attention to detail, as well as technical knowledge about the materials being joined and best practices in the field.[1][2]

Welding, without the proper precautions appropriate for the process, can be a dangerous and unhealthy practice. However, with the use of new technology and proper protection, the risks of injury and death associated with welding can be greatly reduced. Because many common welding procedures involve an open electric arc or a flame, the risk of burns is significant. To prevent them, welders wear personal protective equipment in the form of heavy leather gloves and protective long sleeve jackets to avoid exposure to extreme heat and flames. Additionally, the brightness of the weld area leads to a condition called arc eye in which ultraviolet light causes the inflammation of the cornea and can burn the retinas of the eyes. Full face welding helmets with dark face plates are worn to prevent this exposure, and in recent years, new helmet models have been produced that feature a faceplate that self-darkens upon exposure to high amounts of UV light. To protect bystanders, opaque welding curtains often surround the welding area. These curtains, made of a polyvinyl chloride plastic film, shield nearby workers from exposure to the UV light from the electric arc, but should not be used to replace the filter glass used in helmets.[3][4]

A lot of welders relate to getting small electrical shocks from their equipment. Occasionally, welders might work in damp crowded environments and they consider it to be a "part of the job." Welders can be shocked by faulty conditions in the welding circuit, or, from the work lead clamp, a grounded power tool that is on the bench (the workpiece or the electrode). All of these types of shocks come from the welding electrode terminal. Often these shocks are minor and are misdiagnosed as being an issue with a power tool or the power supply to the welder's area. However, the more likely cause is from stray welding current which occurs when current from the welding cables leaks into the welder's work area. Often this is not a serious problem, however, under the right circumstances, this can be fatal to the welder or anyone else inside the work area. When a welder feels a shock, they should take a minute to inspect the welding cables and ensure that they are clean and dry, and, that there are no cracks or gouges out of the rubber casing around the wire. These precautions may be life-saving to the welders.[6]

Recent discussions on government regulations has Josh Welton revisiting something he wrote in 2020 following a massive explosion in Beirut. Reports deemed the incident a welding mishap. Were welders to blame, or were they scapegoats?

Skilled welders are in high demand. Students who complete our welder production program have had great success finding jobs in their field with local companies doing everything from heavy-duty production work to decorative welding.

On just about any vehicle restoration or new build, you'll eventually need to weld metal. Instead of bringing your vehicle to a welding shop or trying to track down a friend with a plasma cutter, shop at Eastwood for automotive welding supplies. We are proud to carry an assortment of shop welders along with the accessories and protective gear that you need for accurate and safe welding. Eastwood has been developing quality welders and other products for do-it-yourselfers and pros since 1978 and has an Eastwood welder or plasma cutter that can help you do the job right.

Whatever type of welder is right for your shop, we are here to help you get the best welder at the best price. A TIG or MIG welder will give you a clean bead on a variety of metals. MIG welders usually mean faster, easier work for beginners while a TIG AC/DC Welder creates higher-quality welds for experienced users. Our Flux Arc and Gas Welders are great for less-than-ideal welding conditions like dirty/painted surfaces and wind. Need options? Multi-process welders let you easily switch modes depending on the type of weld and the material you're working with. There are many Eastwood welder reviews from real customers to help you decide which one is right for you.

Sometimes you need to cut metal before you can join it together. Eastwood Versa-Cut Plasma Cutters will slice right through metal cleanly and quickly. They also are more precise on curves than mechanical cutters. A 3-in-1 welder and plasma cutter combination will let you slice through metal and then weld it in one continuous process. Eastwood also has many welding packages that include a welder, plasma cutter and welding cart at a discounted price.

Of course, you'll need more than just a welder to complete your next project. Eastwood has all the right products for a successful build. You'll find clamps and tools for holding parts together for welding; surface preparation tools to prepare your welding project; quality consumable wires like filler wire, welding tips and nozzles; and welding carts for rolling equipment around the garage.

The AWS Certified Welder program is open to anyone with a talent for welding. This program was developed through input from volunteers throughout the industry and is designed to provide transferable credentials to professional welders who demonstrate the required skills. This means your earned credentials reflect an industry need.

The AWS Certified Welder program allows for welders to obtain multiple certifications to expand their credentials. Every certification that a welder earns increases the number of skillsneeded to perform a wide range of welding jobs. See a list of certifications that a welder can obtain through the CW program.

CW tests are performed at AWS Accredited Testing Facilities (ATFs) located throughout the world, and candidates must make an appointment to participate. These testing facilitiesadhere to strict standards for welder testing and can test welders to AWS Standard Welding Procedures, industry standard specifications, and company-supplied or non-code weldingspecifications.

The AWS Certified Welder program is designed to provide transferable credentials to professional welders who have demonstrated a skill level wanted by industry. Volunteers, representing all sections of the welding industry, came to a consensus on the skills an AWS Certified Welder must demonstrate. This means your earned credentials reflect an industry need.

A testing laboratory or facility can become nationally accredited by submitting an application and meeting all the requirements under the AWS QC4 Standard. This Standard assures that this lab or facility has met the basic requirements for equipment and its calibration, procedures, and knowledgeable personnel. The requirements of QC4 assure quality control of welder testing for the industry.

The Forney Easy Weld 140 FC-i is a powerful flux-core wire welder. This machine is ideal for do-it-yourselfers (DIY), maintenance, repair, metal fabrication, and hobbyists. Like the other Forney Easy Weld machines, this welder is extremely lightweight (weighing in at only 19 pounds!) and portable. This unit is easy to use and features infinite voltage and wire feed speed control. The Forney Easy Weld 140 FC-i is incredibly convenient, as it does not require gas and can run off standard household power as long as you have at least a 20 AMP breaker.

The MassDOT "green card" is a green paper certificate for the purpose of showing that a welder has been certified in a specific welding process and position for on-site field welding on a MassDOT bridge.

Hi,I already purchased the script but cannot get the same result in the preview.Could you make a short video for it ? Because it gives me the same result as the old free welder script.Concave Convex video is not giving the same good results as the three preview images.Thanks.

The location of the nearest AWS Test Facility may be obtained by contacting AWS at 1-800-443-WELD Ext. 273 or from their Website and clicking Certification. The welder will be responsible for the fee charged by the test facility.

The MIG180 180-Amp MIG Welder With Spool Gun gives you three different welding processes. Like most MIG welders, you can run flux-core wire without shielding gas using the same equipment as you do for MIG. This machine also adds aluminum welding to your shop's arsenal at the best price/performance ratio on the market.

This PrimeWeld 180 amp MIG welder solves the problem with a special gun that replaces the standard MIG torch. The spool gun holds a spool of wire close to the torch end, so it only feeds for a few inches instead of 12 feet or more. The result is a smooth, reliable aluminum wire feed that makes your job easier, which will likely increase the quality of your work.

Designed for spot welding the Micro-Measurements line of CEA, LWK, LEA, LZN and LZE weldable strain gages, this new welder combines an extremely fast spot welding rate with enhance safety and portability features that you have come to expect from Micro-Measurements. The 700B is rugged, efficient and reliable in all types of adverse field conditions.

I had no idea making a DIY welder would be so easy to do. And, it's pretty much FREE!

Additionally, the stick welder you get is definitely better than anycheap commercial welder you can buy.

Why is this homemade thing better than something you can buy? Because when you factor in shipping and labor and the little bit of retail markup - the companies that make typical cheap buzz boxes will skimp on copper as much as possible. Whereas you can use enough copper in this to make something really juicy, and still spend less, to nothing, compared to a store-bought arc welder.

So here's what you need to build a welder:

- Two beat up old microwaves

- Some 10 gauge wire

- Wire nuts

People throw out microwaves all the time, if you keep your eyes on the curbs.

Or, you can get microwaves at the local thrift store for $10 each.

Try the warehouse that processes donations - they have to pay to get rid of tons of broken ones.

Stuff you need for welding:

- Welding helmet ($16 and up)

- Welding rods ($6)

- Vice grip or purpose-built electrode holder ($6 for either)

- C clamp for grounding clamp

- Gloves

- Thick nonflammable (leather) clothing that will cover your arms
