Here is how an efficient induction heating machine works

Induction heating is by far the most convenient and cost-efficient material heating process for the present industrial generation. To attain a highly efficient induction heating process, all you need is an electrically conducting object when subjected to varying intensities of the magnetic field. Hysteresis and losses due to eddy current go hand-in-hand to initiate the process of induction heating within your electrically conducting field.

How does your induction heating machine work?

To initiate the induction heating process, an induction machine first pulses DC at a high-frequency range. Ideally, this frequency range undergoes optimization at 160 kHz to induce. This direct current pulsing introduces constant magnetic field change. This magnetic field change introduces eddy currents within your conductive material near its coil. Hysteresis thereby heats up all the ferromagnetic material that is present there. The heat is generated due to the rapid change introduced in the magnetic field.

This process of induction heating is highly efficient compared to other alternatives as the heat wastage here is much less. Throughout the process of induction heating, there is no contact taking place in between your inductor machine and the parts subjected to it. You will not find the presence of any combustion gases either. Place the material you want to heat in a setting, isolated from the main power supply.

Here are some part characteristics to keep an eye on

Magnetic or non-magnetic in nature

Heating of magnetic material is relatively more comfortable than a non-magnetic variant. Besides the heat generated by eddy currents, the magnetic materials itself produce some heat described as the hysteric effect. Relative resistance or permeability of magnetic material is around 100 to 500 while that of non-magnetic material is around one.

Thick or thin

As around 85 percent of the heating process takes place on the surface of the material, small or delicate parts heat up more quickly in comparison than the thicker variants.

Resistivity

Materials possessing higher electrical resistivity are able to actively resist the current flow. This process quickly produces heat.

Manufacturers of induction heating machines are emphasizing more on their product quality control with the introduction of cutting edge induction technology. Red-D-Arc is a prominent name in this regard.

Are you aware of media blasting equipment?

Professional media blasters are always in search of the best media blasting equipment for increasing their overall efficiency. When your equipment is right, and up to the mark, it will naturally multiply your profits. Here is a quick reference guide to help you understand blasting equipment.

Types of abrasive blasting equipment available in the market

Your blasting equipment falls into three different categories:

Tumble blasters

These are enclosed cabinets equipped with a rotating basket and a sandblast gun. These blasters work on the mechanism of random tumbling actions to ensure uniform sandblasting of all the parts placed within it. This tumbling process aims at removing rust, scale, and burrs, which ultimately produce a brightly colored or dull finish as per the requirement.

Cabinet Blasters

These blaster types are available in three different styles namely standard cabinet blaster, split-level cabinet blaster, and portable cabinet blaster. They are ideal when dealing with large and heavy blasting parts.

Portable Blasters

Portable blasters are available in the pressure fed or gravity fed variant. They are suitable for use in refinishing vehicles, monuments and brick buildings.

Important points to consider while buying blasting equipment

1. Cleaning speed and efficiency

Cleaning speed of the blaster is directly proportional to the compressed air utilized. The more CFM (cubic feet per minute) you opt for, the more heat your blasting equipment will generate under any pre-defined blasting pressure. 

2. Size of your blasting cabinet

It is never good to opt for a cabinet size in alignment with the part size. Larger cabinets can generate the right amount of visibility as the abrasion expands at a comparatively lower particle density within the assembly. With larger cabinets, you can have good part mobility, which favors both movement as well as rotation.

3. Filtration

A dust collector is the reason why your production cabinet suits well for the production work. It generates the right amount of negative pressure, is cleanest and highly efficient in its mode of action.

The buyers should be aware of these basic points about media blasting equipment to avoid production loss.

Hence, choosing the right media blasting equipment is necessary if the production team aims at profit maximization with minimal investment.

Some Smart Tips to Follow While Using Pipe Welding Machines

Welding is the process of joining two metal pieces. In fact, this practice doesn’t merely join the pieces together as in soldering or brazing but also causes the metal to amalgamate and become one. When it comes to pipe welding, you should have a reliable pipe welding machine. Two basic rules can make this process much easier. The first one of these is to set the machine correctly and the other one is to make yourself comfortable. Let’s discuss more about these rules.

Proper equipment setup

As a welder, you must never deviate from this rule. A pipe welding machine requires you to set the equipment in any position without the need to change any settings. For TIG or Stick welding, one could alter the heat intensity with the arc length. For instance, when welding at the pipe’s bottom you require more heat, you can increase the length of the arc a little. This will improve the welding process appreciably. Vertical areas can be short-arched a bit to lower the heat. Essentially, the pipe welding equipment must be on such a setting that it enables you to weld in all positions without altering the voltage or amperage.

Getting in the most comfortable position

The level of comfort during pipe welding is enough to separate a newbie from a seasoned welder. However, it is unquestionably true that any of the professional or novice would have to work in several uncomfortable situations. Pipes could either be underground or high up and you may need to get creative to find the most comfortable position. The easiest method would be to lean on a pipe. This would provide your hands and body a steady platform to concentrate on the welding procedure. You just need to be attentive and creative.

Some Important Points to Ponder About Welding Positioners

Positioning equipment helps welders in maneuvering and welding huge assemblies with ease. However, you can also position several small assemblies mechanically. In fact, the positioning principles are similar for both large and small parts that need welding, i.e., you need to fix the base to the equipment and maneuver it mechanically. This will allow the most efficient assembly and welding.

Regardless of the size of the weldment, welders need to follow some important tips when choosing, working with and maintaining a welding positioner.

Attaching the machine parts correctly

The way of attaching the positioning equipment to the weldment is important, as this is where the separation would occur naturally. Chucks and fixtures add significant weight from the face plate and need proper care during the sizing of the positioning device. Of the many positioners available, slots allow the piece that you are working with to be bolted to it. Whether it is a stand-alone method or a combined method, it would work great if applied properly.

Keeping it Flat

Whether it is small or big positioning equipment, you need to mount the unit to an even and flat surface, which could secure it in place. In case mounting holes are present, you can use them to secure the positioner and prevent its tipping in case it encounters any kind of unexpected force. A welding positioner mounted on a stand or a workbench is equally important to secure.

Using Turning Rolls

If the machine part to weld is cylindrical, you can roll it easily. Turning smaller rolls can rotate a vessel or a pipe down hand the welds. These power rolls offer a stable rotation, which produces uniform circumferential weld. The idler rolls are not powered but you can add them into series in order to provide support to longer vessels and pipes. The combination of a vertical-faced table welding positioner and a roller-type pipe stand offers protection and stability during the extension of a round part. When the rollers offer two points of contact, there is an even distribution of weight.

While researching for welding positioner, these considerations could help you to make up your mind in singling out the most feasible one.
