Different Type of Welding Machines

In case of electric welding, there are a variety of best multi-purpose welding machines. Electric welding machines basically are of 5 different kinds. Those are-

·        FCA Welding Machine

·        Spot Welding Machine

·        SMA Welding Machine

·        MIG Welding Machine

·        TIG or GTA Welding Machine

Now let us discuss the above-mentioned multi-purpose welding machines in respective orders so that we can understand the essence of each welder in working field.

 

Flux Cored Arc Welding: This multi-purpose welding machine basically comes up with a melting feed wire that is heated up by an arc. This machine can be easily described as if it is an open fire gun. The trigger is the switch by pressing it the wire feed starts coming out until the trigger is freed or the wire is fully consumed.

Some advantages of FCAW-

i.                    As the wire feed only melts and simple application of triggering make the welding purpose done, it is very easy to learn and with work on.

ii.                  Rusty and dirty surfaced materials also can be treated with this.

iii.                If there is hardly any required position to weld, it can be really efficient.

iv.               It has a higher rate of deposing materials.

v.                 This welding can be done on a material which has a lot of thickness, it can penetrate through the width.

 

Spot Welding: Mostly it called resistance welding. The process it is done is, two metals are to be welded and for that opposite side of the side to be welded, electrodes are connected and the passing of electricity is made through. Fusion occurs and the pieces get welded attached.

Some advantages spot welding-

i.                    Like the previous, it supports both steel & stainless steel.

ii.                  Easy learning & implementing the procedure.

iii.                In this welding, there is no use of gases.

 

SMA Welding: It is regularly known as Stick welding as well as Shielded Metal Arc Welding. This process is mostly covering pieces of metal and heats them up to melt and join itself and those are heated up by the arc and covered with metal like rod and lastly shielding spray on the surface using particular gas.

Advantages of SMA welding-

i.                    This can weld steel and stainless ones along with cast iron and aluminum.

ii.                  It is one and only welding machine run by electric which can weld cast iron.

iii.                Any outside environment condition will work for this.

iv.               It also welds on thick products and dirty or rusty materials.

v.                 This welding is reasonably priced in comparison to others.

 

MIG Welding: Metal Inert Gas welding works almost like the stick welding. But it differs when the metal pieces are kept with the electrode and continuously heated by the arc and feed wire while to shield the process different required gas is mixed and passed through the process. For different wires unlike gases are used. For Steel, Stainless Steel and Aluminium it needs CO2, Argon, and mixture of these two with helium respectively.

 

Some advantages of MIG welding-

i.                    This welds aluminum besides steel and stainless ones.

ii.                  Open feed fire is easy to apply and learn the process.

iii.                It has a neat after weld condition which is quite good to use.

iv.               Fast welding machine, for quick weld requirement.

v.                 Amazingly it can weld thin materials and has a good control over it.

vi.               Like the above other welding machines, it also can be applied if there is no position.

 

TIG or GTA Welding:

Tungsten inert gas or TIG multi-purpose welding machine has a process to joint metals by firstly forming an arc between electrode and base material and heat it up. The electrode which is the tungsten is not going to be melt and get added up to the melding. And for shielding purpose Argon gas is used as inert gas.

Some advantages of TIG welding-

i.                    It welds alloys basically of magnesium as well as aluminum if it is an alternate connection.

ii.                  In case of direct current this welds titanium, copper steel and stainless ones.

iii.                If you need a weld which is very compact and accurate you need this.

iv.               Like the previous, it also has a good control to weld thin elements.
