Using Holding Clamps and Magnetic Ground When Welding

Whether you should use magnetic welding grounds and clamps by addressing the advantage and disadvantage of their durability concerns, use, equipment cost, and some potential alternatives, this article is aimed at providing answers to the question. 

Magnetic Welding Grounds and Clamps

There are many advantages to using Magnetic Welding Holder, magnetic welding grounds, and clamps. Why magnetic welding ground and clamps were invented in the first place most of them point back to the reason: for added convenience.

Pro: It becomes much more convenient to weld towards the middle of circular steel, square, large structural, or rectangular pipe. A magnetic welding ground makes grounding your weld In the case of welding on an oversized workpiece such as pipe, – in some instances – possible.

Pro: welding productivity is increased by Using magnetic grounds and clamps instantly. Magnetic grounds and clamps allow the user to simply stick a magnet onto the surface of the work piece and start welding instead of twisting traditional screw-type clamps out and in.

Pro: when welding sheets of metal, Magnetic clamps are worth their weight in gold which needs to be constrained in a perpendicular orientation without any elaborate fixtures or jigs. In the corner of the hold and joint the workpiece securely a magnetic clamp can simply stick to the metal.

Pro: grounding becomes easier or even possible in applications where you are welding on a workpiece which has only a portion of the base metal exposed (such as in an automotive repair shop where in a certain area a body panel is taken down to bare metal only).

Pro: Wedges and dogs are used for sheet metal fit-ups using Industrial Magnet can decrease cost. Costs can be decreased in labor simply by using an optimized magnetic work holding solution.

If you need assistance or if you have either determined that you need magnetic equipment for your welding application, it is strongly recommended to visit your local welding store deciding on this type of equipment.

Tips in Selecting A Rare Earth Magnet

The term rare earth magnet is a generic name that is used to describe two types of magnetic material:  samarium cobalt and neodymium iron boron.  These two magnetic alloys utilize rare earth elements and Magnetic WeldingHolder as the magnetic constituents and the characteristics that these both material offers lend themselves to specific applications.

30 years ago in response to the rising cost of samarium cobalt, neodymium magnets were developed by General Motors and Sumitomo Specialty Metals. Neodymium iron boron has undergone numerous enhancements since its inception, and at present, this material is the most popular and widely used magnet alloy. It’s very much necessary to know that there are hundreds of patents covering the production of sintered neodymium iron boron magnets. At Dura, the neodymium iron boron supplied is licensed and compliant with all applicable patents.

Among all magnetic materials (including other rare earth), the highest available magnetic energy density with BHMax values ranging from 33 to 52 MGOe is offered by neodymium iron boron. When compared to other magnetic materials this physical property allows designers to use relatively small amounts of magnetic alloy.

However, the increased savings associated with neodymium and the smaller magnets might suggest you in selecting a high strength Rare Earth Magnet as the perfect choice among all applications but this is not always the case. Factors that cause premature failure and substandard performance are ignoring important characteristics such as operating temperature or the magnet’s ability to withstand corrosion. You will find the availability of alternative high-temperature grades of neodymium iron boron and various surface treatments when the rigors of the application demand it.

Apart from the fact that both are called rare earth magnets, there are few similarities between samarium cobalt and neodymium iron boron. With BHMax values ranging from 16 to 32 MGOe samarium cobalt offers the second-highest energy density, but SmCo magnets are also very brittle.  Due to this physical characteristic, while integrating samarium cobalt magnets with a given application it is important that designers and engineers must take great care. Samarium cobalt because of its capacity to function at elevated temperatures up to 662°F sets itself apart from other magnet materials. For high strength/high-temperature applications samarium cobalt is often the rare earth magnet alloy of choice.

Know about Shielding a Magnetic Field

A magnet, traveling charged particle, or current has a magnet around them, which is a neighborhood having a magnetism that will act on another magnet, traveling charged particle, or current. This field is sort of evident once you drop iron filings around the Magnetic Filter Rod, and you'll see a particular pattern forming along the lines of this field.

A magnet might be of varied varieties sort of a static magnet which is an object made up of a cloth that's magnetized and creates its own magnetic area. the opposite variety might be an electromagnet which is produced from a coil of wire which acts as a magnet when an electrical existing is gone by means of it.

When magnetic flux is employed during an application, there are instances when an object has got to be shielded from this field, and this is often done by a procedure called shielding. Shielding material is employed, which alters the lines of the magnet. The fabric actually, conducts the sector lines along a path of least effort that it creates. Therefore, shielding isn't to be taken in its literal meaning, as lines of the magnet aren't blocked or stopped, and only their path is altered. The shielding material offers a coffee energy pathway for field lines to travel and is the best conductor than air.

The next aspect to think about is the size of the shield. An outsized shield is going to be obviously exposed to more lines of the magnet; however, these lines won't be induced to travel through the shield. Usually, during a practical home setting, a shield measuring six-foot square would be sufficient for shielding the space that's beyond two to 3 feet from the magnetic source in Motor arc Magnets.

The shielding material also will differ consistent with the strength of the magnetic flux. For strong fields, materials like Groin, Paper Shield, and Magnet Shield is quite effective, and that they provide good permeability and high saturation. Consider all factors, measure the magnetic flux, and determine the extent of attenuation required, before you begin your project on shielding the sector.
