Welding, basically, is the act of joining metals. While welding has been around for a long time, these days welders, or welding machines, make it possible to make extremely tough joints between two pieces of metal.
The welding of metals, in some form, has been around since the bronze age, but it wasnt really until the 1800s that the discipline really began to take off. With the dawn of the 20th century, and especially World War I, welding and welders entered a new age. Kennedy Welding provides aluminium welding service in Brisbane.
submarines, bridges, aircraft, vehicles and just about anything else which was made of metal. Since that timArc welding, which is still popular these days, was used during that era to make e, a plethora of welders and welding technologies have emerged. Here is brief rundown of the most common welding types:
Arc welding: This type of welder utilizes a power supply to make an electric arc between the welding machine and the base material. It creates sufficient temperatures to melt the metals and ensure a durable join. There are numerous different types of arc welding, these include shielded metal arc welding, gas metal arc welding, metal inert gas welding and tungsten inert gas (TIG) welding, to name just some of them. Even now, arc welding is still by far the most common form of welding in existence.
Gas: Gas welding processes like oxyfuel welding, sometimes called oxyacetylene welding, have become a little dated in recent years but are still among the most versatile kinds of welding. Not only can gas welding be utilized to join metals, the equipment is also ideal for cutting metals, brazing and melting. The welding flame, a combination of acetylene and oxygen, can reach temperatures of up to 3,100 degrees celsius.
Resistance welding: Though not as popular as arc or gas welding, resistance welding can be the right option in certain situations, though it can be expensive. Heat is made by passing a strong current through two metal objects. The resistance caused by the contact of the two metal objects causes them to melt at the weld area and makes a join.
Energy beam Involving either laser beam welding or electron beam welding, this method is usually used in high-production processes. Nevertheless, it is still worth mentioning. High energy beams are employed to make high-quality, precision welds very quickly. The process is very efficient and is easily automated, but these welders are very pricey.
For a lot of day-to-day and smaller industrial welding jobs, the arc welder will be the most popular choice. They are inexpensive, handy and can be used for all kinds of welding tasks. In addition, there is no need for gas or oxygen tanks. A low-cost arc welder sells for around the $350 mark, but of course you can splash out a lot more than that for more expensive products.
