Welding is an ancient art that has been traced back to the bronze and iron ages. While the tools and techniques have changed slightly over the centuries, the basic principal behind welding still remains the same. Two pieces of metal are joined together through a process of heat and pressure, resulting in a solid piece of metal with a connection joint just as strong as the metal itself when done properly. Today, welders make use of a variety of different welding supplies to complete their tasks. The exact type of welding equipment being used will vary depending upon its application and the type of welding being employed.

The most common type of welding done today is known as arc welding, which uses an electrical arc to create the heat needed to complete the weld. There are several different welding supplies that will need to be used in these jobs. The most important is the electrical supply, normally a portable box that creates and maintains a steady power supply that travels down a cable to the welding wand. The other key component in this type of welding is the electrode, normally a steel coated welding rod that not only completes the electrical arc but also melts down and forms the actual joint compound during the weld. The supplies needed for this process are inexpensive and easy to find.

Gas welding supplies are also common and a bit more volatile. This type of welding uses a constant electrical source and a gas mixture. Supplies in this case will include the power supply and the gas itself, which is why you'll frequently see large gas tanks around most welding shops. This process uses materials that are more expensive than arc welding, but the welding process goes much quicker when gas welding is being employed since the electrical current is constant.

Beyond gas and arc welding, the cost of welding supplies rises drastically. There are numerous different types of welding including friction, laser beam, and even robotic. Obviously, the actual robotic welding apparatus will cost a good bit of money and even a laser welder can reach into the tens of thousands of dollars. New technology continues to come out, giving professional welders more and more options when choosing just what types of welding equipment to purchase as well as what types of welding they want to try their hand at. The only restriction for most is cost.

In short, the types of welding supplies that you'll need as a welder will vary. At a bare minimum you'll need a source for the electrical current and welding compounds. Arc welders will need a good supply of electrode based welding rods while those who use gas will have to ensure that their shop is stocked with the gas they need at all times. Protective gear is also a must and will include masks, gloves, and aprons to protect the welder from the extremely high temperatures associated with welding jobs. Whatever type of welding you do, you'll need to be aware of the supplies needed.
