Probably, STICK welding is the process most widely used worldwide. The reason behind this might be its simplicity, portability, and good deposition rates. It is often considered the most basic and easiest form of welding.Nevertheless, not everyone likes this process. Some people consider that with so many other options nowadays, using STICK welding might be like going back in time. So, let’s dig deeper into what STICK is and what can still be used for.Baca selengkapnya -
Stick welding is one of the oldest types of welding and is still widely used today on various applications, such as construction and earth moving equipment, thanks to its simple technique. While it may not be as easy as MIG welding for a beginner, it’s definitely not as hard as TIG welding.Stick welding is a good middle ground and is perfect for those who don’t want the hassle of a gas tank or want to weld thicker pieces of metal.Baca selengkapnya -
If you are first learning SMAW, you may want to opt for a user-friendly rutile electrode. However, anyone who plans to weld professionally or critical structures (and that includes farm implements) should learn with the electrodes used for these applications, and that means mastering basic and cellulosic electrodes.Baca selengkapnya -
Stick welding is one of the oldest and most certainly one of the most widely used welding methods across various industries. The advantages include low cost, high versatility, speed, and penetration, making it a favorite in multiple industrial applications.However, Stick welding can also be highly versatile for home and DIY projects and on-field repairs. That's why, in this article, we'll delve into the core principles, equipment selection, safety measures, and step-by-step techniques on how to Stick weld. Once you get the hang of it, you can achieve strong, durable welds with this versatile and enduring welding process.Baca selengkapnya -
If you are going to weld in a position that is steeper than 45 degrees, you have to realize that you will be against gravity. The 7018 electrode was designed for this very purpose. Classed by the AWS (American Welding Society), this is the perfect choice because the 7018 has a lower content of iron powder. This particular electrode makes a weld puddle that is able to freeze almost instantly and won’t drip off while working. You can also use the AWS classed 6010 stick but this electrode requires a certain whipping or stacking technique in which you pull the stick out of the puddle and put it back in intermittently. You can use the 6100 for the same kind of work but 7018 is known to give better results and a quicker weaving pattern.Baca selengkapnya -
It might have crossed your mind if it is ok to hold a stick welding electrode when you weld. Or you might have seen others do it. But when is it helpful, and how safe is it?You can hold the electrode when stick welding (SMAW) for a short time to improve the electrode’s stability when striking the arc or making tack welds. When doing so, you must wear dry welding gloves in good condition.Baca selengkapnya -
Stick welding, while not the hardest form of welding to learn, can still be difficult at times. Getting an arc to ignite on the first try is absolutely a skill, and not everyone can do it. Starting an arc isn’t the only tricky part of stick welding, so if you’re looking to improve your welding, give these tips and tricks a try.Baca selengkapnya -
I'm putting together a grant application on advanced FSAW-type piezoelectric resonators coupled to a transmon qubit. To my points: Can you supply 4 inch or 6 inch wafers with thin films of Niobium deposited? >If so, what substrates are possible and what layer thicknesses, and do you have any characterisation of the layer morphology, properties, etc.? Is Niobium on Lithium Niobate possible? >Would it be possible to give me a quote, or an indicative non-binding ballpark price, to assist me with preparation of the grant? Thanks for taking the time to read my message. I'm really excited about this project, so if this is work you are interested in then I'd be very keen to pursue this. In any case, if you can let me know, I'd appreciate it. Best regards, have a good day.Baca selengkapnya -
The word piezoelectricity comes from the Greek word piezein, which means squeeze or press and electron, which means “amber” and is an ancient source of electric charge.The French physicists Jacques and Pierre Curie discovered in 1880 that electric charges could accumulate in certain solid materials in response to an applied mechanical stress.Piezoelectric materials allow conversion of energy from the mechanical domain to the electrical domain and vice versa. They can be used to create various sensors or actuators: applied periodic electrical signal can result in the generation of ultrasonic waves for imaging purposes.Baca selengkapnya -
Piezoelectric actuators and other piezoelectric components feature a compact size and low profile, no electromagnetic noise, and a host of other advantages. For this reason, they are increasingly used for auto-focus actuators in cameras and for other applications. Currently, the only practical piezoelectric materials are lead-based materials, and so lead-based materials are widely used in piezoelectric components.Although the lead contained in piezoelectric components is not subject to the RoHS directive and other environmental regulations, it is preferable that a lead-free alternative be developed for the future. Also, lead-based piezoelectric materials cannot be co-fired with Ni, and so currently, high-cost Ag/Pd (palladium) is used for the inner electrodes when stacking. Lead-free piezoelectric materials, on the other hand, enable the possibility of use of low-cost Ni. This paper presents our work in successfully fabricating lead-free multilayer piezoelectric ceramics with Ni inner electrodes.Baca selengkapnya -
The wrap-around is another common electrode pattern. The wrap-around electrode pattern is typically used when you need to connect more electrical leads to the same surface of the piezo component. This may be relevant if you want to bond the opposite surface of the component against a flat surface. This specific electrode pattern is often used on “thin” piezo components.Please note, the un-electroded band of the electrode pattern must be as wide as the thickness of the component. Therefore, this pattern is not suited for very thick components with very small electrode surface areas.There can be many variations in wrap-around electrode pattern placement and dimensions. Therefore, it is necessary to have a drawing of the desired electrode pattern. Noliac can provide drawings and specifications in order to get full agreement about the design.Baca selengkapnya -
Piezoelectric ceramics must go through electrode application and polarization before they can be used properly. Electrode application is a crucial process that determines how piezoelectric ceramics will be assembled with other components. Furthermore, many of our customers’ requirements are closely related to the electrode application of piezoelectric ceramics. Therefore, through the following article, we would like to introduce the knowledge about electrode application of piezoelectric ceramics.Baca selengkapnya
