Welding : Basic Information

Welding is a process using heat or pressure to join materials such as metal or plastic. This is a common way to join metals, and is used in the production of various goods, including cars, boats, trains, buildings, and bridges. Although similar to the action solder and brazing, welding distinguished from other methods in a molten weld metals together, while soldering introduces a softer substance that melted and then used to store the original piece without actually melt them.

Welding has developed a conception so since thousands of years ago. Thanks to modern technology, a welder who worked with the precision of much larger and stronger than welding Welds in pre-19th century, when forge welding is the only technology and welded metal by blacksmiths beat them together on the coals heat. First World War created a new wave of advances in welding technology, as many countries look better and more efficient way of welding for ship and aircraft welding technology increases war. Like That, welding, such as being more powerful and can now be done by hand or automatically by the machine and even a robot. Welding can be done in a variety of environments, including under water, and welding equipment can be very portable. Despite this progress, welding remains dangerous, with risks to the welder burns, exposed to toxic gases and damage the eyes.
