Equipment for welding comprises of materials or devices utilized for a wide array of purposes. Specifically, it is used for the so-called joining processes like arc, resistance, laser, electron beam, stud and orbital welding. Among a list of processes served by used equipment are wave soldering and a variety of brazing techniques.
Welding machines and systems may operate through the use of a welding power source. Sometimes, one may need a weld controller to facilitate the purposes served by the machine. Luckily, there are also complete systems with a surface or cutting machine, torch, feeders, cables, robots, positioners and feeders. In order to know more about used welding equipment, here is an explanation of processes where it is being utilized.
Welding the arc method
Arc welding involves different facets of welding including MIG and TIG. MIG welding stands for Metal Inert Gas Welding. At times, it may also be referred to as MAG Welding or Metal Active Gas Welding. This is considered as one of the highly popular arc welding processes because of its versatility. It makes use of different forms of gas to complete the process. The list includes pure carbon dioxide, pure argon gas or a mixture of these two chemical components.
Another process known as TIG Welding highly depends upon new or used welding equipment. TIG stands for Tungsten Inert Gas. This process is called as such because it makes use of tungsten when striking an arc between the workpiece and the welding electrode. The inert gas used in this type of arc welding process is argon. When compared to MIG Welding, this one is slower and is usually more expensive.
Welding has other processes included in its list. The likes of flux cored arc welding, gas metal arc welding and resistance seam welding are included. Spot welding and shielded metal arc welding are also popular categories under this welding process.
Other welding processes
Besides arc welding processes that employ welding equipment, frictional welding is also considered to form part of the list. Examples are hot plate welding, plastic welding, electron beam welding and Oxyfuel welding.
No matter how varied these processes are, there is a common denominator that applies to all. This is the fact that when looking for pre-owned equipment for welding, the machine should be able to comply with corrosion resistance, multiple operations and water cooling. Of course a heavy-duty machine that has engine driven generators are highly qualified to fulfill these processes.
