This article is the author's graduation thesis and his own code; Simulation Software Design of automatic batching system for Welding Electrode Design Content Welding rods are widely used in steel structures in construction and industry. A electrode can be divided into solder and solder. Solder is a steel rod with a specified material, length (about 400mm), and diameter (about 5mm). solder is a chemical coat

MSC. Simufact. Welding. V5.0 simulation SoftwareSimufact simulation software is a large and complex software, covering a wide range of functions, in order to provide users with the best solution, simufact and other software companies to take the strategy of cooperation, the various areas of the leading software modules integrated in Simufact software, including solvers, CAD interface, Grid division and material performance simulation. In collaboration

After several circuit board welding experiences and lessons, we will summarize the circuit board welding skills and steps: 1. Check whether the circuit board has obvious faults. For example, some cables in the circuit board are broken due to processing, or the line width is uneven, or there is an open circuit between the line and the passing hole, and so on. Once, when

Always wanted to make a minimum system, this time finally put the idea into reality. Schematic diagram is as follows:The PCB diagram is as follows:After a few days, the board finally mailed to, is the following bear-like.Welding the voltage regulator circuit, found that the voltage regulator circuit schematic part of the wrong, no grounding, and then fly the root line, the regulator circuit is stable and easy to use.Welding Stm32 chip, where VCC and gnd pin hanging tin, the result burned a volta

We received express delivery at noon today. SF is not cheap, and it is indeed fast. Direct air parts. Open the package and use a small box with two groups of circuit boards. The main control circuit board and display and control circuit board are packed in shockproof foam. Black and white characters are separated and the luster is good. We scanned all the boards with the naked eye, and the quality was indeed good.I actually got 12 boards and sent two more. It is estimated that ther

1. Inspection MethodThe inspection method should be determined based on the detection device configurations of each unit. If there is no optical inspection equipment (A01) or online testing equipment, visual inspection is generally used. You can choose 2 to 5 times the magnifiers or 3 ~ The microscope was examined 20 times.2. Inspection content(1) check whether the welding is sufficient and whether there are traces of insufficient Solder Paste melt.(2

Label: Stainless SteelIf the stainless steel sheet is welded by the TIG method without filling material, the chemical composition of the weld metal is the same as that of the base metal, but not necessarily the same organization as the base material. Because the base material is solution-oriented and the carbide and other precipitated materials are completely dissolved and in a saturated state. However, because no filling material is added, although the chemical composition of the weld metal is

Reading books together-reading books in PHP and reading books in php We had to learn about android, and PHP started to read books. Two 500 + books, 45 days not enough, a little busy... The bloat in the morning is just a music stick. Keep a long memory ........ 1. PHP + MY

As a Java programmer, the most painful thing is to choose too wide, can read too many books, often easily confused. I would like to choose some of the technical books I have read, according to the Order of study, recommend to everyone, especially those who want to constantly improve their technical level of Java programmers. In addition, you can join 457036818 Exchange groups and share your knowledge about

[From Renren network source address: http://blog.renren.com/GetEntry.do? Id = 896285182 owner = 274281790,Very touched !!] In the past, I would like to read a book before reading, but in actual reading, I often "want to read a book" rather than "want to read a book ". This kind of thinking often makes my life very painful. When you want to finish something quickly, your mind is no longer in this matter. This problem has plagued me for a long time in college. I don't realize that this is actuall

Java has the introduction of books, read this article you know, this article contains the study of Java at each stage of the book recommendation, the history of the most complete, learning Java, no books How to do, it is like the battle without weapons a truth, these books sorted out to everyone as a reference for learning, especially for self-scholars, If you st
