Discussion on the connection mode of lead rod and electric heating wire

At present, there are two kinds of connection methods between lead rod and heating wire used by domestic electric heat pipe manufacturing enterprises:
One is to use the welding machine spot welding method, and the other is relatively simple to use the lead rod thread tooth and the electric wire directly on the way. For the former, more than 95% of the electric heat pipe production enterprises are used, and less than 5% of the enterprises use the latter, and sometimes the use of very little enterprises tend to create better results.
Under normal circumstances, the welding machine spot welding method is more solid and reliable, and there is a risk of using the lead rod thread tooth and the heating wire directly on the way, and even the possibility of falling off. The contact is not good, and the risk of falling off at any time is not strong. In fact, think carefully and otherwise, anything has a dual nature, Lin Zhi for the two ways of detailed comparison.

Through the comparison of the above content, it is found that the advantages and disadvantages of using the welding machine spot welding and using the lead rod and the electric heating wire directly on the welding method are just the opposite. In the actual production process, the method of spot welding with the welding machine is not as good as the method of directly screwing the rod and the electric wire without welding, especially when adding powder, it can highlight the advantages of non-welding.
Although there are certain defects in the way of directly screwing the leading rod and the heating wire without welding, it can be avoided by technical means, and the adverse effects of non-welding can be completely eliminated. The key lies in the design of technical design parameters, which can meet the standard requirements of use, so the way of directly screwing the leading rod and the heating wire without welding is still worth trying.

At present, the thinking of domestic electric heat pipe production enterprises is relatively common and traditional conservative, and the innovation model is backward, and many enterprises are following the rules and regulations to carry out production step by step, especially in the current lack of breakthrough traditional thinking, daring to try to be the world's first.
Some time ago, I went to a household heat pipe manufacturer, and I accidentally learned that the fixing method of the flanges and electric heat pipes produced by a foreign company is neither ordinary chlorine arc welding nor welding with solder, but everyone's unexpected is only fixed with glue curing, which is really a little surprising, and it is absolutely not feasible to fix in this way in China. Even makes people feel a little strange, I am afraid that no customer can be willing to accept the use. At that time, I also questioned the strength of the glue after curing, and conducted a destructive test on the strength of the electric tube curing on the spot, proving that my idea was redundant and the strength was very strong. And they have now carried out mass production, indicating that they have broken through the traditional way of thinking, especially the customer can accept that this way of production in the technology has fully guaranteed their use requirements.
The method is actually very simple, but do not dare to try, so that it is convenient to operate and save costs but also to meet the requirements of use. For example, the method of directly screwing the lead rod and the electric heating wire without welding can be used, but more importantly, the technical design is controlled, especially the design of the parameters is particularly important. For example, the leading rod of M2.5 wire teeth with 0.4 wire diameter heating wire is very suitable for winding the wire with a swallow rod of 1.8 outer diameter around the needle, but the heating wire with 0.4 wire diameter is a little too tight, resulting in a relatively tight spinning wire, and the heating wire with 0.3 wire diameter below is a little too loose. Like the length of the wire, the wire diameter of the electric heating wire, the outer diameter of the winding needle, the choice of the tightness of the winding wire, etc., so the design of the parameters to achieve the best fit state is the most important.
In fact, it seems very simple to screw the rod and the electric heating wire directly without welding, as long as it is properly used, it can create better results and improve certain production efficiency.
