CMT cold metal transition welding technology, which was demonstrated by Fronius company in 2004 European plate Technology Expo, is a new welding technology without welding slag spatter. The so-called cold metal transition refers to the digital control mode of short arc and wire reversing wire feeding monitoring. The reversing wire feeding system is composed of two sets of welding wire conveying mechanisms, which make the conveying process of welding wire intermittent. The rear wire feeding mechanism feeds the wire forward according to the constant wire feeding speed, while the front wire feeding mechanism controls the pulse welding wire conveying at the frequency of 70Hz according to the command of the control system
the digital welding control system can know the start time of arc generation, automatically rece the welding current until the arc goes out, and adjust the medium pulse welding wire delivery, which effectively improves the transfer of welding wire droplets. After the droplet drops from the welding wire, the digital control system increases the welding current again and further sends the welding wire forward. After that, the welding arc is regenerated and a new welding process is started. The alternation of "cold heat" greatly reces the generation of welding heat and the conction of welding heat in the welded parts. In addition, it can also achieve a variety of functions: it can correctly set the parameters of the droplet, achieve better weld thickness transition, and has a high welding speed without any spatter. According to Fronius company, the equipment greatly improves the welding proction capacity, and can effectively ensure the welding quality of the welded parts

Panda Global, blockchain game. Blockchain digital pet, each panda is a unique indivial. Points can be used to buy and sell pandas. Alt male pandas can marry with female pandas, so that they can breed all kinds of exciting and cute new panda varieties. They can also dig gold in feeding. The ability and speed of different grades of pandas to dig gold are different. The higher the grade, the faster the panda

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. bitcoin is an important concept of bitcoin. It is essentially a decentralized database. As the underlying technology of bitcoin, it is a series of data blocks generated by cryptography. Each data block contains a batch of bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block

characteristics of blockchain and blockchain games

1. Decentralization. Due to the use of Distributed Accounting and storage, there is no centralized hardware or management organization in the system, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system

2. Openness. The system is open. In addition to the private information of all parties to the transaction is encrypted, the data of the blockchain is open to all. Anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

3. Autonomy. Blockchain adopts consensus based specifications and Protocols (such as a set of open and transparent algorithms) to enable all nodes in the whole system to exchange data freely and safely in a de trusted environment, so that the trust in "people" is changed into the trust in machines, and any human intervention does not work

5. Anonymity. Because the exchange between nodes follows a fixed algorithm, the data interaction does not need to be trusted (the program rules in the blockchain will judge whether the activity is effective). Therefore, the counterparties do not need to make the other party trust themselves by disclosing their identities, which is very helpful for the accumulation of credit

In the English clothing dictionary, CMT is the abbreviation of cutting, making and finishing, which means processing fee. In the clothing dictionary, it can be said that it is the manual fee for completing a garment

CMT is a way of cooperation, namely cutting + making + trimming, processing fee + auxiliary material fee

refers to processing with supplied materials. That is, the importers provide certain raw materials, semi-finished procts, spare parts and meta equipment, and sometimes also provide relevant equipment and technology. The processing enterprises of the exporters process and assemble according to the requirements of the importers, and the finished procts are sold by foreign businessmen, and the exporters charge processing fees

generally, the operation of FOB is to have a certain comprehensive strength. The most troublesome problems of clothing foreign trade are three: price, delivery time and quality. To make FOB orders, we have to bear these three risks. The delivery date of fabrics will seriously affect the delivery date of ready-made clothes, and the main factor affecting the delivery date of fabrics is the quality of fabrics. Sometimes it takes a long time for customers to confirm the quality of fabrics (physical and chemical properties such as color, handle, etc.), and finally the garment factory has no time to proce
