If you visit the local machine shops around your area and see just what it is they do, you are in for a treat. Welding is simply joining two different metals into one. Sounds easy? Well it’s not. Welding metals requires a lot of study and understanding of the metals themselves and the many factors that come along with it in actually joining it. If you take too long in exposing the metal from the welding materials heat source, it could easily break. Precision is the key in welding.
Among the many ways to weld, two particular methods rise from the list which are used all over the world. Almost all machine shops may incorporate one or both of these styles depending on which tools they have.
1. Arc Welding
In this style, numerous sub styles were created. Basically, arc welding is creating an electric arc which melts and later connects the two metals. There are many versions of arc welding such as the gas metal arc welding, tungsten inert gas welding and the Shielded metal arc welding.
2. Torch Welding
This is the most popular choice in welding. Using oxyacetylene torch, the welder melts and working material and controls the rod. This is commonly the choice for artistic metal works and sculptures.
Both are the most common methods used. If you want to weld something, consider the price that comes along the welding materials.
And always remember, safety first! There are standards to what safety gear should be worn by the welder from the top (headgear), to eyewear, to heat-resistant jackets down to rubber-soled safety boots. You never know when accidents occur so it’s better to be always stay safe than sorry.
