Used in industrial equipment, the heating wire burns out after being energized for a period of time due to long use or other reasons. How to weld the joints of the heating wire is a technical activity, but it is directly related to the service life of the heating wire. There are very simple welding in the current social market, such as: winding or lamination or metal conductor connection method to treat the joint after the heating wire is blown, but there are also some shortcomings: the joint is easy to oxidize; after thermal expansion and contraction, The joint is easy to loosen. In use, the resistance at the joint will increase, arcing will occur, and the joint will easily be blown again.
Now introduce the joint method of connecting the heating wire with glass wire: first prepare some glass scraps that have been smashed into rice grains or powder, and then remove the oxide at the broken ends, and then wrap the two broken ends for 2 to 3 times. After power on , Put the prepared glass pellets or powder into the joint. For high power, use rice-sized glass chips; for low power, use powdered glass chips. After the glass flakes are melted, the joints are firmly connected together. This connection method will neither change the power of the heating wire nor cause the heating wire to burn again at the original joint.
The above is a simple analysis of how to effectively connect the heating wire and how to make better measures when such problems occur.
