What kind of welding head suits you

In the soldering profession, welding head, as a supporting product, is recognized by the profession, and this kind of product is familiar to the industry. According to the division, this kind of product can be divided into different types, such as internal heating type and external heating type, and welding head has a wide range of applications. The production of this kind of products pays great attention to the process, and the main products should play the role of welding. The soldering rate of the products is very high, and the temperature requirements are also relatively high, so that the talents can blend metals well. In order to better melt the welding metal and avoid oxidation, the surface of the product must be cleaned before welding to avoid that oxidation welding can not achieve the effect.

Each electric soldering iron manufacturer is equipped with different types of welding head (soldering iron nozzle, welding nozzle), but the basic shapes are pointed, horseshoe-shaped, flat nozzle-shaped and knife-edge shaped. Each kind of head is basically the same, but the difference lies in the size of the body part, so as to match with its own electric soldering iron and welding table. The current situation of welding head (soldering iron nozzle and welding nozzle) with different brands of general soldering iron and welding table is also different. However, there are exceptions. For example, because the general external heating soldering irons (30w, 40w, 60w ...) are generally used at low prices, the welding head (soldering iron nozzle, soldering tip) in the market can be used. The other is 900m series used in 936 welding table. Although there are many brands of 936 welding table, they are all evolved from white light 936 welding table. All 936 welding tables and 900m series in the market can be used together

On the surface, we can't see how to judge lead-free welding head products. Now there are many kinds of lead-free welding head on the market, and each manufacturer's production technology is also different, and there is also a big difference in quality. How to judge whether it is good or bad, Xiaobian teaches you the following methods: 1. To really understand its good or bad, it is still necessary to judge it from other things such as service life. 2, shape, do not need to consider the shape color, no matter what it is black, bright, white, the surface plating color is for two purposes: rust prevention and anti-creep tin, no matter what color, the surface must be chromium, chromium is just to avoid creep tin. 3. The higher the scale and precision, the better. What you need to care about is several key scales, such as the scale of the device and the ruler of the head. 4, destruction, this is a more intuitive way to judge, use a file to cut off the head, look at the inside of the base must be red copper, iron layer should be thick, but not too thick, the thickness between 0.8~1.1 mm is the top grade. 5. Lead-free. If it is a lead-free welding head, the pre-tin on the head may not be very beautiful. Because the fluidity of pure tin is not strong, the surface will look a little dark. If the pre-tin on the head is too bright and beautiful, whether to guarantee lead-free should be discussed carefully. Generally, sgs report should be selected. To sum up, the application and choice of welding head is very important. How to choose welding head with good real cost performance. It is still far from enough to judge only by appearance. The better way is to use it directly and make a comparative trial in the production line.
