The development of handheld laser welding machine

 The development trend of handheld laser welding machine



Continuous laser welding is divided into two types: fiber laser welding and semiconductor laser welding. The key difference is that the light spot of the optical fiber is very thin, and the light spot of the semiconductor is relatively large. It can be simply considered that the spot size is different. Fiber laser welding is 2-3 times faster than semiconductors, the key initial light spot is small, the kinetic energy is concentrated, and the welding penetration is good.


Laser welding has achieved rapid development in recent years. Fiber laser welding has the advantage of speed, but it requires extremely high product workpieces. The gap is within 20 wires, and it is difficult to guarantee mass production for many hardware processing. To better solve this problem, the shaking fiber laser cutting head appeared. Simply speaking, shaking the laser cutting head is to draw a circle. It will be easier to understand by using a description. Everyone draws a parallel line with a ball-point pen, which is long, slender, and thin; if there is a ball-point pen to draw a circle, draw one immediately, and it will be relatively wider. This basic principle is that the fiber laser shakes the laser cutting head. The laser is continuously drawn in a circle to expand the total width of the seam welding. The grinding time after welding was too long, and the labor cost and consumables cost increased year after year. After laser welding is selected, the seam welding surface is neat and beautiful, which greatly reduces the polishing time. Manpower, grinding, and polishing consumables have also been greatly saved. Hardware polishing and polishing have been an annoying matter in terms of environmental protection in recent years. Laser welding is less polished, and it is easier to implement environmental protection regulations.

An indispensable automatic sorting robot in the supply chain?

 Automatic sorting robot , without human hands, autonomously complete equipment sorting work, or machine sorting work as you call it. It is said that in recent years, in logistics companies with labor shortages, robot activities have increased. However, even if you introduce robots just because it will be easier, you may end up with "just the cost is too high...". Recently, the development of intelligent robots is getting faster and faster. There are various types of automatic sorting robots. ① AGV It is called an automatic guided vehicle or an unmanned transportation robot. It is a robot that can operate automatically without manual operation and is used to move objects to a designated location. ② Arm type It is used to move products from one box to another, which is usually done manually. ③ Rail type From packaging to automation of the distribution area to a series of automations for carrying goods, it is a rail-mounted robot. The automatic sorting robot is very effective i...

What Logistics Is and What It Means For Business

Logistics is a topic that deals with the transportation of material or goods, especially over distance. The logistics industry helps businesses transport items such as raw materials and finished products from suppliers to consumers. What is Logistics? Logistics is the process of moving products and materials from Point A to Point B. It is a critical component of business and helps companies get their products to their customers on time, in the right condition, and at the right price. There are many different logistics solutions available to businesses, depending on their specific needs. Some common solutions include transportation, storage, warehousing, and distribution. Logistics can be complex and challenging, but with the right tools and strategies, it can be managed successfully. Some Logistic Benefits 1. Logistics is the process of moving products and materials from one place to another. It’s a key part of business, and it can be used to move anything from small shipments to large...
