Choose The Best Welding Method

Welding is a joining process employed to melt and join metals and thermoplastics. Almost all types of metals and thermoplastics can be welded by using different welding process.   By definition, welding is defined as a sculptural or fabrication process. The process is completed by causing coalescence.   The process is completed by filling the joining point with a metal or melting the two pieces together to become a unit of molten material. One of the popular welding is Metal insert gas welding which also known as MIG welding. Only a best mig welder can give you the perfect finishing and versatility. A best mig welder will be handy in dealing with aluminum, mild steel and stainless steel welding.

A best tig welder technician must have some idea about different types of welding.   Because in projects, there will be different type of welding have to be employed. It won’t practically possible to employ different type of welders in a project. The types of welding have to be selected as per the project requirement. If the project required only a low cost welding and required to weld some pipes and tubes, it is better to engage with Gas Welding.   This is an old type of welding which is also known as Oxy Acetylene Welding.

TIG and MIG welders are required good experience.   The qualities of the welding are much higher than that of electron beam welding or shielded metal arc welding.   TIG and MIG welding are used by large industrial houses and now a day home welders are also using these types of welding.  When you choose between TIG and MIG welding an experienced best tig welder technician can explain you to consider the factors choose the best welding method.  In general, MIG welding is involved high maintenance and the start up expenses is high.

It is quite interesting to go through the history of welding. With available historical evidences, the welding techniques seen developed during Bronze Age and Iron Age.   The technology that led to modern welding has been started by the invention of metal electrode by Sir Humphrey Davy in 1801 when he invented electrical arc.   This technology was further enhanced by Nikolai Slavyanov with the invention of electrodes in the year 1880.   The welding technology leaped further with the introduction of resistance welding, oxy-fuel welding, thermite welding and arc welding.   The World War I and World War II contributed much more improvements in the welding technology.

During the Second World War and after the War there were tremendous development happened in the welding technology. Stud welding and submerged welding were developed after Second World War and these welding technologies are very popular and have been using for various applications. Welding process has to be considered as per the application requirements and each welding technology has its own advantages and disadvantages.

Some of the most popular welding process and its uses are given hereunder:

  • MIG Welding: This is the short form of Metal inert gas welding, which is also known as GMAW (Gas Metal Arc Welding). This is a fast welding process and with proven versatile qualities. MIG Welding is suitable for mild steel welding, stainless steel welding and aluminum welding. A best mig welder can give required satisfactory results.
  • SMAW Welding: Shielded metal arc welding in short is called as SMAW welding which is done by using stick arc welding rod.   This is commonly used in home welding and an easy process and easy to master the technique.
  • Oxy Acetylene Welding: This also known as Gas Welding and also used for metal cutting purpose. This is one of the oldest welding techniques mainly used during repair works, sheet welding, patching works, welding tubes and pipes. For this welding Oxygen and Acetylene gases mixed through a nozzle and flamed to produce heat.
  • Resistance Welding: For this no filler is required and its production rate is very high.   In this method heat resistance is generated from two or more metals.   The welding is very energy efficient but the weld strength is very low.   So this is good for only where there is only low strength is required.
  • TIG Welding: Tungsten inert welding is known as TIG welding and in other words it is called as GTAW (Gas tungsten arc welding) and good for joining two pieces together.   For this welding process tungsten electrode and inert gas are used along with filler material. Filler material is placed between the pieces to be welded.   The result of TIG welding can produce high quality welding and hence only a best tig welder can produce the required result.

There are so many factors to be considered while selecting the best method of welding suitable for your requirements. As every welding type is not suitable for all welding requirements select the best welding process by evaluating the defects and merits. In MIG welding, in the merit side you will have effectiveness, easy to master, extra low hydrogen, high deposition rate, less cleaning, faster welding time, low skill requirements, no wastage of time, good weld result and in defects you will have high maintenance cost, initial high set up cost, more sparks and smokes, stable atmospheric conditions.

In TIG welding, you will have good quality welding, less sparks and smokes, auto genous welding, can be used in all type of metals and in the defect side, you will have skilled welder requirements, costly equipments, longer welding time and complex welding process.

Right process, right energy and other factors will be the deciding factor to select the best welding method for your work.
