Thread Content
This post was last edited by xh8618 on 2017-8-17 08:34, with bg9.png (question) – Why cannot welding be used to connect the wiring ducts in instruments? In what situations are shielded wires mainly used? Note: If the question is ambiguous, please contact me privately; however, no detailed explanations or word-by-word analyses will be provided. After responding, the reference answers can be viewed; points are awarded if the correct answer or the key points are provided. The answer is: The methods of connecting wires include welding, crimping, hinge connection, and connection using standardized connectors. However, if welding or plating is used for the wiring conduits in instruments, damage will occur and oxides will peel off in layers. Shielding is used in applications where protection against strong electromagnetic field interference and oxidation corrosion is required. —————————————————————————————————————————————————————————————— The deadline for submitting answers is one week; no scoring will be given after that date. The deadline is 207.08.24. Scoring criteria: For incorrect answers, 1 wealth point is awarded; if the answer is incomplete, 2–6 points are given. Correct answers accompanied by detailed explanations earn 8 wealth points, while correct answers with insufficient additional details result in 10–15 wealth points. Please score according to these criteria. Note: If there are editing records after answering, only those who participated will be credited points. For continuous malicious spamming, 2 points will be deducted each time, with no upper limit. Pure numbers, pure emojis, or random letters that have nothing to do with the answer are all considered malicious spamming; points will start to be deducted after three warnings.
1. If it is difficult to pass the wire through after welding. Changing the line is even more troublesome. 2. Analog signals must be transmitted using shielded cables. Computer control cables must also be shielded cables
Welding is not used because the protective pipe is usually made of galvanized steel pipe, and welding would damage the galvanizing layer； Shielded wires are used in areas where there is electromagnetic interference in the environment surrounding cable installation
1 If the wire conduit is welded, its coating will be damaged and oxides will peel off in layers. 2 It is used in applications where protection against strong electromagnetic interference and oxidation corrosion is required
If the wire conduit is welded, the coating will be damaged and the oxide will flake off in layers. Used in applications where protection against strong electromagnetic field interference and oxidation corrosion is required.

If welding is used for the wire ducts, the coating will be damaged and oxides will peel off in layers. It is suitable for applications where protection against strong electromagnetic interference and oxidation corrosion is required
Welded together; if the wire conduit is damaged and cannot be replaced, shielded wires are mainly used in environments with interference to eliminate such interference without affecting the actual performance.
