Different types of welding are available, with the most effective method depending on the materials and skill level. Wire, arc, tig, tungsten gas arc, and spot welding are all options. Safety equipment should always be used.
There are several types of welding to choose from. Most commonly, welding involves joining two materials, usually metal, together to create a single object. The most effective means of welding metal depend on the types of metal and the skill level of the person doing the job. Other factors include the types of equipment available and personal preferences.
One way to weld metal is known as wire welding or gas metal arc welding. It is often used to weld small objects together and is completed using a welding gun or torch. The operator pulls the trigger on the device and a small piece of metal pops out inside the torch barrel. The heat from the piece of metal works to create the weld.
Arc welding is another way to weld metals together. Also known as shielded or manual metal arc welding, it uses an electrode that puts electricity into metals to create a weld. This is one of the more popular forms of welding because the operator of this device doesn’t have to be extremely skilled to create a workable weld.
A slightly less common way of welding metal is tig welding. This technique uses both a torch and a stuffing rod. To create the weld, the fixture operator inserts filler into the weld as he goes. You can also use tungsten gas arc welding, where the heat from the torch melts one or both of the connected pieces so they can be fused together. This process can also be called “melting”.
Another method of welding metal is known as spot welding. It is a large device with two arms, each of which holds one of the pieces of metal that will be joined. An electric current is raised through the two pieces. This process generally takes just over a second to complete. Spot welding is usually used for things like sheet metal fabrication.
Choosing the right type of welding device and strategy will depend on the experience level of the welder and the type of welding to be performed. Arc welding and tig welding, for example, can be used on many different types of metal. Fuse welding, on the other hand, can take some time with certain materials. Researching melting points and proper soldering techniques beforehand will ensure a worry-free experience.
Whatever process is used, it is important to use the proper safety devices. Always wear goggles, gloves and other equipment to avoid injury. In addition, welding devices should only be used as intended, carefully following all manufacturer’s instructions.
