PTA Welding Machine – The Ultimate FAQ Guide

Hardfacing mechanical parts, components, and workpieces isn’t an easy thing to do. In fact, it requires special equipment that can get the job done swiftly.

Are you in this type of business? If so, then it’s best to choose a company that uses PTA Welding Machine.

What is PTA Welding?

PTA, or Plasma Transferred Arc Welding, is a welding process that uses a tungsten electrode to create a high-density arc.

PTA Welding

In most cases, it’s the welding process you will use for hardfacing on mechanical surfaces.

What are PTA Welding Equipment?

PTA Welding Equipment are the machineries or equipment used for PTA Welding.

PTA Welding Equipment

These are the types of machines you need to use to perform hardfacing or cladding to your machines.

The most common parts or units PTA welding equipment has include:

  • Column & Boom
  • Powder Feeder
  • Water Chiller or Recirculator
  • Power Source
  • Weaver or Welding Oscillator
  • PTA Torch
  • Welding Positioner
  • Process Control Panel

What is the PTA Process?

It’s a liquid-state welding process, where the metal-to-metal joint forms into a molten state.

PTA Welding Process

In the process, you use the hot ionized gases to heat the workpiece or the surface. Due to the heat, fusion happens and the weld is completed.

What is Plasma Arc Welding (PAW)?

Plasma Arc Welding or PAW is a welding process almost the same as the PTA.

Plasma Arc Welding

They use the same method but differ on the materials utilized.

The difference is with the filler material you will use:

  • PAW uses filler metal in wire form
  • PTA uses filler material in powder form

What are the Fields of Application of PTA Welding?

Whatever industrial sector you are in, you can greatly benefit from PTA Welding.

PTA Welding Applications

The most common applications you can have for it include, but not limited to:

  • Forging of Matrix Dies and Moulds
  • Making Corrosion or Abrasion Resistant Industrial Equipment
  • Improvement of Automotive, Petrochemical, and Marine Valves
  • Enhancement of Lamination Rollers and Rollers
  • Enhancement of Cutting and Milling Tools
  • Development of Parts for Nuclear Plants
  • Developing Industrial Cutters and Blades
  • And Many More

What are the Advantages and Disadvantages of Plasma Arc Welding?

Hole From Welding (Disadvantage)

Plasma arc welding has a ton of advantages, some of which include:

  • High Rate of Deposition
  • High Heat Concentration
  • More Freedom to See and Observe the Weld
  • Low Pollution
  • Less Expensive or Costly
  • Controlled Penetration

Apart from that, though, it also has certain disadvantages, which are:

  • Generation of Smoke and Noise
  • Difficult to Make Sharp Corners
  • Wider Heat Affected Zones and Weld Areas
  • Produces Infrared and Ultraviolet Radiation

What is Plasma in Welding?

In welding, the hot ionized gas that forms in the process is called the plasma.

Plasma Sample

Plasma is formed due to the ionization of Argon that passes through the electric arc.

Is Plasma Safe?

Yes, plasma is safe to use and it’s not different from other compounds.

But, just like others, there are precautionary standards you have to follow.

What is Plasma Welding Used For?

Plasma Welding Uses

Generally, you would want to use plasma welding if you want to achieve the following:

  • Better Control and Quality of the Output
  • Cleaner, Smoother, and More Specific Designs
  • Higher Heat Tolerance
  • Lower Cost of Welding

What is TIG Welding?

TIG is short for Tungsten Inert Gas Welding.

TIG Welding

It is a type of welding that produces the weld using a non-consumable tungsten electrode.

Is TIG Welding the Same as Plasma Welding?

No, TIG welding and PTA welding are two different welding processes. In TIG welding, you would form the arc using a tungsten electrode.

TIG welding is the process you can use for workpieces and surfaces that are thin and brittle.

In plasma welding, you would place the electrode in the torch and the arc is gas-infused. This ionizes the gas, forming the electrical arc.

Plasma welding is a process that is better known to cut materials and surfaces.

Can You Use TIG Welding Machines as a Plasma Cutter?

Yes, you actually can.

TIG Welding Machine Plasma Cutter

TIG welding machines have features that you can use to cut metal or steel. However, it might not be as good as a plasma cutter.

Can PTA Welding be Done Using Tungsten Carbide?

Yes, in fact, it’s the usual type of carbide used in the PTA welding process.

Tungsten Carbie PTA Welding

Tungsten has tough and resistant properties. So, they are the perfect material to help improve the durability of your machines.

  • Lincoln Electric
  • Miller
  • Elektriska Sventsnings-Aktiebolaget (ESAB)
  • Hobart Welding Products
  • AHP
  • Everlast

What is PTA Hardfacing?

It’s the process of applying metallurgic deposits on workpieces.

It uses the plasma transferred arc method for deposition and for the coating procedure.

PTA Hardfacing

Hardfacing’s goal is to improve the properties and the durability of a part or component.

What is Hardfacing?

Hardfacing is the application of material to a surface or a workpiece through welding.

Hardfacing Sample

The most common materials you would need to overlay your parts are:

  • Corrosion Resistant
  • Wear Resistant
  • Abrasion Resistant
  • Erosion Resistant
