Information On Welding Baltimore Processes

By Grace Rivas


Welding Baltimore is a common fabrication process mainly used in joining mostly metals. The procedure involves melting the metal at the edge where you intend to add the joining material. This material should be added at the molten state. To ensure you come up with a strong joint, the molten material should be allowed some time to cool down. This method of joining enjoys much popularity given the efficiency and that it is very cost effective. Shared here are various ways to join materials through this process.

Stick type is the first method also commonly referred to as Shield metal Arc Welding (SMAW). People derive the slang name from the resemblance of the rod to a stick. The procedure depends on power to come up with an arc. This arc is then used to burn an electrode or a rod, which is mandatory equipment in the process. A rod is metallic by nature but has an external flux coating to keep air off the site to be welded as the rod burns.

This process is widely used because it is simple and practical. It is also cheap and works well on most of the metals which require being joined. These qualities make it the perfect joining process for most of the industrial building requirements. It is the foundation to learning other types of metal joining processes in most of the institutions where these processes are taught.

Another type is MIG which is abbreviation for Metal Inert Gas. This type uses an arc too and it is considered one of the easiest to learn. It uses a wire which is fed to the joint to be welded. This wire is usually connected to a constant power supply which enables it to produce an arc for it to melt when it comes into contact with the joint to be weld.

An MIG gun is used in this method. It helps to combine electricity, the rod and the shielding gases at a go, and this ensures quality product. To start the joining process, you need to pull the trigger of the gun. This process is used in factories where fabrication of metallic product is large scale. This gun is easy to operate; however, you need experience to put the correct settings.

TIG is another method used which means Tungsten Inert Gas. Just like the previous two methods, it also uses an arc. Many people look at it as the most difficult method to learn. It is considered a superior method since almost all metals can be joined through this technique. A technician will make use of both his hands to come up with a joint. One of the hands will be handling the torch which produces the heat and arc through a tungsten rod while the other hand will feed the electrode.

An arc is created from current drawn from power supply. In this method, a filler metal, which in most cases looks exactly like a wire, is introduced to the joint to be welded. This method is most suitable for specific metals that demand a higher quality of weld. The biggest challenge with this method is the high cost involved in acquiring the equipments.

The last in the list is gas which is according to many people the ancient method of welding Baltimore. This process mostly uses oxygen and acetylene gases. The heat used is usually generated from a flame that emanates from a burning gas. It is recommended for automobile because of its versatility and the fact that it is portable.
