The process of joining or fastening two pieces of similar metals (work pieces) is called welding. It could be done by melting and fusing. One has to be very careful before choosing a welding tool since they determine the final appearance of the weld. Some important factors should be. Some essential factors to consider are discussed below—
The welding process is one of the most important issues. You cannot use just one welder for all purposes. Different welding process needs various types of tools. So before choosing a welding tool, you have to keep in mind the process you are going to take. The available methods include—
- Metal inert gas or gas metal arc welding (MIG)
- Tungsten inert gas or gas tungsten arc welding (TIG)
- Shielded metal arc welding (SMAW)
- Gas Welding
- Resistance Welding
- Energy beams welding
- Solid state welding
Safety should always come first. Before choosing welding tools, make sure that you have your safety tools. Fire resistant jacket, welding gloves, safety glasses, and a helmet is needed. Also, ensure sufficient ventilation for proper fume extraction. Avoid welding next to flammable materials.
Some procedures are better for welding certain materials. For example, you can’t weld aluminium using the MIG process. If you use as pool gun to feed the consumable, you will get better results. The reason is aluminium doesn’t feed well through a wire feeder and a long cable. Sometimes welding tools are varied according to material’s nature or thickness.
Higher voltages are sufficient for welding thinner materials; lower voltages are for thicker materials. So it will be wiser to choose a tool which supports dual voltages so that you will get the benefits of different input voltages.
Portability is another factor you should keep in mind before choosing a welding tool. Do the work pieces require to be brought to the welder or the welder requires to be brought to the work pieces? Generally, portable welders are easy to carry.
