What is Welding? What is welding, and how does it work? Not many people know what welding is or how it works. Welding is the process of heating and melting metal parts to join them together. A welding machine uses electricity to melt the electrode, fusing one piece of metal to another. The welding machine uses a ground that connects to the surface that allows the welder to create a flowing current passing through the electrode and the metal that the welder is wanting to fuse together. Electrodes can come in many different sizes and with different types of flux. The flux is the protective coating that is around the welding rod protecting the weld as it is being melted to the metal. There are a few different ways to learn welding. High schools …show more content…

Long sleeve shirts are also used for heat protection and keeping sparks from burning a welders skin. The welding helmet is necessary for the welder to watch as the weld is being formed on the metal. When the welder strikes an arc it is incredibly bright and can only be seen through the welding helmet which has a dark tinted lens. Now there are electric welding helmets that are light before the arc is struck and instantly become dark when the welder sticks an arc, protecting the welders eyes and face from the bright flash and sparks that are created from welding. The proper shoes are necessary when welding. Closed toed shoes are needed to protect his/her skin from sparks that come from welding and from any metal that might fall on the welder’s feet. Long pants also protect the welder from heat as well as sharp objects. Many experienced or retired welders start their own welding company. There are many expenses for independent workers. Depending on the size and type of the welding machine the prices are different. A stick welder can be anywhere from $299 to $3000 and higher depending on the size of the machine. Welding rods for the welder cost about $25 per box and can come in many different sizes and flux types. MIG welders sell for $200 to about $2000 and up also depending on

    Now it is feasible to weld, starting from thin metal sheets of fraction of mm to very thick plates of virtually any thickness. The quality of welding is not restricted only to work done by the welder but depends on many other factors, viz. welding technique and its parameters, welding equipment, shielding medium, working environment, etc. The heat input rate is one of the most important variables in fusion welding, since it governs heating rates, cooling rates and weld pool size. In the welding of steel, this is important relationship since increased cooling rates increase the risk of hydrogen-induced cracking.

    There are jobs everywhere for welding, however how much you would like to make depends on where you are willing to work at. In my home town of Streator one of the main welding manufacturing shops is vactor which majority of our residents work in. Entry level wage for welders is typically $17/hr or higher. Welding can be very hard on the body when safety precautions are not taken. All welders should wear safety equipment such as: safety goggles, welding mask with proper shade, gloves, flame retardant jacket, pants, boots, and a welding cap. The purpose is to ensure the safety of the welder and those around him. Safety precautions are not only taken by the welders but also the supervisors and managers. It is their job to manage the exhaust in shops by law, many welding shops have ventilation systems installed just like the one in our welding shop. There are ways around not having a ventilation system; for example vactor workers carry specialized venting systems built into their welding masks. Many of the health problems older welders face down the road could 've been prevented if they would have took the proper safety precautions when they were younger. The most common welding process used in welding manufacturing is mig, the reason being it is fast and efficient. Mig also leaves far less spatter so it makes for cleaner welds (Petkovsek). Welding manufacturing is also safer because workers are not

    To begin with a welder uses equipment to apply heat to metal in order to create a permanent bond. In doing so, they weld metal parts, fill holes, and can even repair cracks in a brace. Because of its heavy duty strength, welds can be used to repair cars, ships, and even airplanes. Also, welds are used in the construction of buildings and bridges. Various tools are needed to perform proper welding techniques, for example, a person may need clamps, welding rods, a chipping hammer, a torch, glasses, a welding helmet, an apron or non flammable clothing to properly weld metal. In addition, a person may also need a specific type of welder for a certain occasions. For example if a person wants to weld aluminum a mig welder would be used along with argon and helium gases. Safety is always important for the welder. Welders are exposed to a variety of environments and situations that put their safety in jeopardy. They are at risk for cuts, bites, stings, and burns since they work outdoors. They are also exposed to gases, dust, fumes, and foul odors due to working in poorly ventilated areas. It is ev...

    There is some basic equipment that is needed while welding. First and foremost, a welding mask is needed to protect the eyes from the extremely bright light created by the arc. UV light can also come from arcs, so eye protection is needed for this as well. Another necessary piece of safety equipment is gloves. A thick protective specially designed welding glove is used for the hand that is holding the torch, and a thinner glove is optional for the hand that isn’t on the torch as well. Heavy cotton clothing, especially long sleeves and jeans, is necessary as well. The long sleeves and pants will protect the skin from the extremely hot spatter than can fly off everywhere when welding. Leather is preferred if doing a lot of welding at one time.

    When outdoors, they may work on a scaffold or platform high off the ground. They may have to lift heavy objects and work in awkward positions while bending, stooping, or standing to work overhead. Welders are exposed to a number of hazards including very hot materials and the intense light created by the arc. They wear safety shoes, heat resistant gloves, goggles, masks with protective lenses, and other equipment to prevent burns and eye injuries and to protect them from falling objects. They also work in safely ventilated areas in order to avoid danger from inhaling gases and fine particles that can result from welding processes. Because of these hazards, welders have a rate of injuries and illness that is higher than the national average. Most welders work full time and work overtime. Many firms have two or three eight to twelve hour shifts each day. As a result welders may work evenings, nights, and even
