Welding is the process of getting metal surfaces to join together by using high heat to melt them together. Vices are often used to hold the pieces of metal until they have molded together. Welded metal is very strong and it is often hard to tell if two pieces of metal have been welded together. This process of welding is used in industry all the time. It is much stronger than solder or other joining techniques.
There are many types of welding. Forged welding was used by blacksmiths to put two pieces of metal together. They would get the metal hot and use a hammer to make it go together. This is believed to be the first type of welding ever used. Arc welding is commonly used today for construction and in home workshops. This type of welding uses a power source to make an electric arc.
Spot welding is a form or resistance welding. This is commonly used in businesses and on sheet metal. This type of welding allows you to weld a particular spot that other types of welding can’t get done without getting the entire surface area hot.
The type of welding you will use depends on many factors. The important thing is for the weld to be amazingly strong. Factors to consider include the amount of heat needed to get the materials hot enough, the design of the material, and the design of the joint. It is important to test the strength of the weld. Not all metals hold a weld very well. Steel and sheet metal work best.
Since you will be working with heat and often with metals that have sharp edges, it is very important that you wear heavy gloves and eye protection when you are welding. You should also wear long sleeved clothing to prevent burns. You should only use welding equipment after being properly trained in how to operate it.
