How much do you know about the workmanship of solder lamps? Not all materials can be connected by soldering, only a part of the metal has good weldability (Strictly speaking, it should be the nature of soldering)In order to connect with soldering. Generally, copper and its alloys, gold, silver, zinc, nickel, etc. have good weldability, while aluminum, stainless steel, cast iron, etc. have poor weldability. Generally, special flux and methods are required for soldering. If the composition of lead-tin solder does not conform to the specifications or the impurities exceed the standard, the quality of solder will be affected, especially the content of some impurities, such as zinc, aluminum, cadmium, etc. Even the content of 0. 001% will obviously affect the wettability and fluidity of solder, reduce welding quality. No matter how brilliant the chef is, he cannot produce delicious food with inferior raw materials. This is obvious. Different flux should be selected for welding different materials. Even for the same material, different flux is often used when different welding processes are adopted, such as manual soldering iron welding and immersion welding, different flux is required for post-welding cleaning and non-cleaning. For manual soldering, Rosin and active rosin can meet the assembly requirements of most electronic products. It should also be pointed out that the amount of flux must also be paid attention to. Too much or too little is not conducive to tin welding. Solder lamps also need to go through the soldering process of soldering to weld each lamp piece together, let the lamp reflect its overall beauty. In the process of soldering, the soldering master should check it one by one.
