Its official name is Shielded Metal Arc Welding (SMAW), but it’s usually called stick welding. This type of welding employs an electrode (stick) and can be used for welding almost all the ferrous metals and other metal types, too. It is among the most widely-used welding processes.Წაიკითხე მეტი -
Stick welders are considered old-fashioned today. But that doesn't mean they are out. Even though MIG welders are becoming a choice tool for fabrication needs nowadays, there are certain things a stick welder continues to be better at.Წაიკითხე მეტი -
Welding is a process used in fabrication for thousands of years. Different types of welding help fabricators forge swords, build ships, build furniture, and more. There are many kinds of welding to choose from, each with specific practical applications. When you start, you will find that some welding types are easier to learn, while other processes can take years to master.Წაიკითხე მეტი -
“Welding” is any method of joining two materials together. While welding often refers to joining metal pieces, welding can apply to other materials, including plastic and wood. Because of this variety, numerous kinds of processes are used to weld materials together. Even something as simple as glue can be considered a welding method.Წაიკითხე მეტი -
Oscar Kjellberg invented the world’s first coated welding electrode in 1904 by dipping a bare wire into a mixture of carbonates (including wood pulp, or cellulose) and silicates to act as a binder. While advances in metallurgy, electrode coating composition, and manufacturing techniques continue to this day, the fundamental principles of shielded metal arc welding (SMAW), also commonly known as stick welding, remain.Წაიკითხე მეტი -
Stick welding is a process by which you can weld two pieces of metal together. It’s sometimes called “stick” or “rod-in-tube” welding machines. The technique has been around for a long time, and it’s still used in the industry.Წაიკითხე მეტი -
The construction industry is extremely diverse, and some of the trades don’t feature welding as a core competency in their day-to-day work. However, equipment breaks, and it’s likely welding will be needed get it back up and running. Or maybe you have some downtime and want to reinforce areas that you know are prone to damage.Წაიკითხე მეტი -
Whether you are a DIYer or a professional welder, one thing is certain: Stick welding requires a lot of skill. It also requires some know-how about stick electrodes (also called welding rods). Because variables such as storage techniques, electrode diameter and flux composition all contribute to stick rod selection and performance, arming yourself with some basic knowledge can help you minimize confusion and better ensure stick welding success.Წაიკითხე მეტი -
When you pick up a shielded metal arc welding (SMAW) holder, you face a wide choice of electrodes. But not all SMAW consumables, also known as stick, work for every material or job.Წაიკითხე მეტი -
Piezoelectric Effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress. The word Piezoelectric is derived from the Greek piezein, which means to squeeze or press, and piezo, which is Greek for “push”.One of the unique characteristics of the piezoelectric effect is that it is reversible, meaning that materials exhibiting the direct piezoelectric effect (the generation of electricity when stress is applied) also exhibit the converse piezoelectric effect (the generation of stress when an electric field is applied).When piezoelectric material is placed under mechanical stress, a shifting of the positive and negative charge centers in the material takes place, which then results in an external electrical field. When reversed, an outer electrical field either stretches or compresses the piezoelectric material.The piezoelectric effect is very useful within many applications that involve the production and detection of sound, generation of high voltages, electronic frequency generation, microbalances, and ultra fine focusing of optical assemblies. It is also the basis of a number of scientific instrumental techniques with atomic resolution, such as scanning probe microscopes (STM, AFM, etc). The piezoelectric effect also has its use in more mundane applications as well, such as acting as the ignition source for cigarette lighters.Წაიკითხე მეტი -
When a force is applied to a piezoelectric material, an electric charge is generated across the faces of the crystal. This can be measured as a voltage proportional to the pressure (see diagram to the right).There is also an inverse piezoelectric effect where applying a voltage to the material will cause it to change shape.A given static force results in a corresponding charge across the sensor. However, this will leak away over time due to imperfect insulation, the internal sensor resistance, the attached electronics, etc.As a result, piezoelectric sensors are not normally suitable for measuring static pressure. The output signal will gradually drop to zero, even in the presence of constant pressure. They are, however, sensitive to dynamic changes in pressure across a wide range of frequencies and pressures.This dynamic sensitivity means they are good at measuring small changes in pressure, even in a very high-pressure environment.Წაიკითხე მეტი -
