Do you deal in metals and often need to weld metals at your workplace? If you are looking for the necessary things you need to know about welding machines before you purchase them, then you are at the right place.
What is welding, and why it is done?
Welding is a fabrication technique that involves melting and fusing metal pieces together at high temperatures.
Welding, unlike brazing and soldering, does not just connect the two pieces together; rather, it causes the metallic structures of the two pieces to fuse together and become one through the application of tremendous heat and, in some cases, the addition of other metals or gases.”
Lower temperature metal fusing procedures such as brazing or soldering, which do not normally melt the base metal, are usually recognized.
Welding normally necessitates the use of a filler material, also known as a consumable. This is utilized to produce a “filler” or pool of molten material that aids in the production of a strong bond between the base metals, as the name implies.
Most welding methods will also necessitate some type of shielding to prevent oxidation of both the main components and the filler.
Welding can be done with a variety of energy sources. A gas flame (fueled by a chemical such as acetylene), an electric arc (electrical), a laser, an electron beam, friction, and ultrasound are all examples. There are a variety of welding procedures that may be used in open air, underwater, and even in space.
Types of Welding
Below are some the types of welding
- MIG Welding – Gas Metal Arc Welding (GMAW)
- TIG Welding – Gas Tungsten Arc Welding (GTAW)
- Stick Welding – Shielded Metal Arc Welding (SMAW)
- Flux Welding – Cored Arc Welding (FCAW)
- Energy Beam Welding (EBW)
- Atomic Hydrogen Welding (AHW)
- Gas Tungsten-Arc Welding
- Plasma Arc Welding
Types Of Welding Machines
There are five main types of welding machines. These are:
- Mig (metal inert gas) welding machines.
- Thyristor Control Mig welding machines.
- Tig welding machines.
- Spot welding machines.
- Shielded metal arc welding machines.
Welding Machine Price In Ghana
Depending on the type of welding machine and the build the price starts at GHS 800 to GHS 10,000.
