Dry Ice Blasting Equipment – Excellent For Product Finishing and Precision Cleaning

Dry Ice Blasting Equipment, used for dry ice cleaning, is an innovative blasting technique in which pellets of dry ice act as blasting media. Compressed air dispenses the dry ice pellets through the nozzle and towards the coating that is being removed. The dry ice is cooled to -79°C which completely removes the coating with no damage to the surface below.

Aero 40

The different effects include:

The Kinetic Effect

Due to acceleration by compressed air, keeping intact with the high velocities, the dry ice pellets collide with the contaminants and thus provokes factures.

The Thermal Effect

The extremely low temperature plays a major role in allowing the dry-ice to remove the coating

The Sublimation Effect

The impacting effect sublimates the dry ice which expands the volume factor by 700. The augmentation bangs out the explosion surfacing up the contaminants.

The unique blasting exclusives

Five Tips for Stick Welding

Stick welding is the oldest known welding process and has always been a favourite among welders because of its many advantages.

The Equipment

In this process of joining, an electrical current is used to fuse the metal by melting the tip of the stick or electrode. The core of the electrode melts with the metal and the outer surface and the flux acts as a shield arc which prevents contamination of the weld.

Tips

See below for the top five tips to help your stick welding equipment perform better:

1. Stick welding does not require you to prepare your surface before hand
2. Ensure the correct power settings are programmed
3. Metals should be iron or steel and thicker than 18 gauge
4. Electrodes should be changed regularly for better results and less spatter. 7018 (vertical welding), 6011, 6010 are most commonly used
5. Keep the arc length consistent

To sum up, stick welding can make, mend, and maintain buildings, pipelines, bridges etc. Although considered old, it is still widely prevalent for its affordability, portability and wide range of work. Therefore, if you want precision in your welding efforts, this equipment is a good option.

Here is Why Linear Seam Welding is Most Important Equipment in Welding Industry

Workshops across various industries trying to produce linear welds confide in linear seam welders. As the name suggests, they create a linear weld across the longitudinal seam of a tubular pipe, or flat plates etc.  Specifically, it is useful for many applications where the edges of the material need to produce a rigid structure after transforming them into the desired shape like a cylinder, rectangular tube etc. 

How it works?

Considered as one of the most effective equipment in welding industry, linear seam welders use pneumatically controlled chrome plated copper clamps to contain thick material of up to three-fourth inch (3/4"). The welding carriage then produces a high quality and consistent weld. The equipment produces linear welds in a range of process including MIG, TIG, Plasma and Submerged Arc. All these processes accompany water-cooled back-up bars with or without gas purge.

How it differs from traditional methods?

Traditionally, linear welding is carried out in different stages, such as the edges of the material are held in alignment, followed by tack welding and then linear welding. This is performed using a simple carriage consisting of the welding torch. However, this process is time-consuming and costlier owing to various factors:

• It is hard to hold the edges accurately in alignment for the complete stretch of the part.
• Equally difficult is to maintain the part’s dimensional accuracy.
• Tack welding consumes considerable time and often causes defects in the tack weld area.
• The less sensitive chilling of weld joint areas could oxidize and distort the surround and weld area.

Seam Welders – Suitable alternative

Linear seam welders provide a befitting solution to all these shortcomings as they have a specific design for the straight line welding in varied thickness of the materials to be weld. In addition, they:

• Minimize cost of welding
• Optimize the welding process
• Improve welding quality

Custom Models

Several manufacturers hold expertise in coming up with custom models based on the requisite functionality and capacity. These include the range of diameter, welded material type, seam length, material thickness (min. and max,) followed by the ideal welding process. Red-d-arc is the best company to consider in this regard, as it holds credible experience in the manufacturing of quality seam welders along with other related equipment.

How Does Plasma Cutting Machine Work?

Plasma cutting machine came into existence with the purpose to cut materials through thermal cutting. Specifically, materials like aluminum, high alloy steels etc., which are not fit for flame cutting, are the best to cut through this machine. Nowadays, various industries also use it for economical cutting of thin and low allowed steels. Here is a brief intro of how this machine works, but before that, it is important to know what exactly is plasma.

About plasma

The theory of matter changing from one state to other with the introduction of heat is nothing new. For example, ice acquires the state of water, liquid and then gas on the application of heat. On applying heat in excess, the gases that form the steam turn electrically conductive and ionized to become plasma. Notably, a CNC plasma cutting machine leverages this ionized gas to perform its task.

Components of CNC Plasma Cutting Machine

• Power supply: It ranges from 200 t0 400VDC and is responsible for maintaining the plasma arc. It provides the requisite energy to maintain the plasma arc after the ionization process.
• Arc static circuit: This high-frequency generator circuit produces AC voltage of 5k to 10k volts at 2 MH approx. It creates a high-intensity spark inside the torch to create the plasma arc.
• Plasma torch: It provides apt cooling (gas or water) and alignment of the consumables like nozzle, electrodes, swirl ring, etc. To improve cut quality, the experts mostly use additional shielding cap for the torch 

These components altogether make up for the ionization capability, electrical energy, and process control required to make productive cuts on different materials with extreme precision and high quality.

Working Of Plasma Cutting Machine

A plasma cutter utilizes electrically conductive gas to transfer energy from an electrical supply to cut the material.Here are the important steps:

1. The formation of plasma arc takes places by forcing a gas like oxygen, nitrogen or shop air through a tiny nozzle orifice inside the plasma torch.
2. An external power supply ranging from 5,000 to 10,000 volts generates a high-intensity electric arc, which is exposed to this high pressured gas flow, ultimately resulting in plasma jet.
3. The temperature of plasma jet rises to 40,000oF within no time, making it easier to pierce through the molten material.
