A Quick Guide On Choosing The Right Welding Machine

Aug 02, 2022


Welding is the process in which two pieces of metal are fused together seamlessly. Welding occurs when a raised temperature is applied to the metal pieces while pressure is created when cooling happens. In some conditions, other metals and/or gasses may be added which causes the metallic structures of the two pieces to combine together and become a singular property. 

Why Is Welding Important?

Welding is a crucial aspect and an in-demand trade of many industries like construction, agricultural, automotive and aerospace to name a few. While it is viewed as an understated skill, without this metal work procedure, it would not be possible for some common things to exist. Most home, kitchen and technological appliances, among other equipment used everyday are made from metal steel that was welded together.Welding joints are specifically created to bear heavy materials and torsional loads.

There are quite a number of different high-end welding methods and processes known to welding technicians today. From spot welding, laser welding, metal inert gas (MIG) which is a type of arc welding that uses a continuous wire called an electrode, and tungsten inert gas (TIG), which come under metal arc welding. Also, since the job involves flammable machinery, welder technicians are expected to wear safety and protective equipment at all times. 

However, no single welding process can be applied to every need or situation. Therefore, to understand the process better, in this welding machine buying guide, we break down how to choose the most appropriate welding machine depending on the kind of welding technique you are looking to use or learn.

Welding usually involves carbon steel metal. Welding carbon steel does not require any complex methods and is often very easy to work with. It fuses into a quality weld workpiece with precision if done correctly.

1. Determining The Required Quality Of The Weld

Identifying the specific metal thickness you will want to weld is essential prior to commencing work. This can help you select the most suitable welder. If you need a high quality weld that might take a good form as an end result, you can go for a TIG welder. If you need to create a strong welding between rusty or metals covered in grime, you might consider a stick or flux-cored welding machine. Additionally, TIG welders work better with all metals or alloys, except cast iron. MIG welding is most suitable for steel, stainless steel, and aluminum alloys.

2. Determine The Welding Position

For instance if the power source is to be moved a couple of times while you perform the task, you can choose a mobile welder that can be tailored to your project needs. You may use either an inverter or one that is engine-driven. Most mobile welding machines are energy efficient while improving the quality of the weld. 

3. Current Usage And Power Source

The duty cycle of a weld is highly dependent on its current usage. Metals that are thicker in structure than other metal bases usually require more power source or current. For this, it is recommended to use sensitive metals which will function more effectively while tracking the right amount of heat. It also includes the site area you will be performing the welding on. A 115 volt supply takes about 140 amperage to weld a quarter inch steel thickness steadily. This is considered the most general input capacity according to industry regulations.
