The Concepts Of Welding In A Nutshell

August 2018 ยท 3 minute read

Simply put, welding is really a metal fabrication process by which two pieces of metal is connected into a huge structure. The location to become joined is heated to melting using torch or electrical arc and further metal material in the form of welding rod or welding wire can be used to fill the visible difference. The welded connections are as stronger since the base material or higher.

There are three basic kinds of welding. These are Gas welding, Arc welding and Spot welding. Inside the gas welding, a gas torch is utilized to heat and melt the bottom metal. Commonly a combination of oxygen and acetylene may be the gas combination useful for gas welding. They are usually useful for welding pipes. The gas welding can be employed for brazing, cutting and heating metal for bending considering that the temperature from the torch flame might be varied.



The Arc welding uses an electric current to melt the base metal. There are different kinds of arc welding designed for handling different metals, equipment and scenarios. Each type could be well suited for welding a certain metal. For joining thin sheets of metals, the spot welding can be used where an electric current is used to produce a weld in a single location. This sort of welding is basically useful for robotic processes. The robots can handle performing large numbers of spot welds in automobile assemblies. There’s also modern innovations in welding like beam welding which can be employed for specific applications.

In virtually every industry from automobiles to electronics, the welding is being used. Welding could be even performed underwater or even in the vacuum space when the welder is offered the correct equipment. Although welding is generally performed on steel parts, the aluminum parts may also be welded together. Some aluminum alloys are particularly an easy task to weld.

Because the welding involves high levels of ac current, gases and temperature, you will need to take certain safety precautions while performing welding. The welders are advised to take extreme caution to protect themselves. Some safety equipments like welding masks, gloves, aprons and coveralls.

The welding masks are shields which cover the top and neck and have darkened glass to shield eyes from high intensity of lights of the welding spark. The masks will be hinged in order that the welders can readily eliminate the mask to judge his work without fully taking out the mask. During welding, sparks are thrown off which would heat and burn the welder’s hands. So for protecting welder’s hands, the gloves needs to be used. It is usually suggested how the welders should wear leather aprons and coveralls for protecting themselves from the heat and gases. Sometimes the welders are located to become operating behind tinted shields. That is in order to avoid passersby from seeing the welding sparks directly.
