Compétences et méthodes de électrique soudure fer soudage: Exigences pour électrique brasage fer soudage:
The solder joints are required to be smooth and round, without "false soldering", and the amount of solder should be moderate, not too much or too little. When using electric soldering irons, different power electric soldering irons should be used for different sizes of solder components (such as electronic components or something larger than electronic components); When welding components, according to the situation, the welding area can be polished to remove the oxide layer or protective film on the surface, and then a tin coating can be applied first to prevent false soldering caused by difficulty in tin coating during formal welding. When welding components, if there are dirt or slag objects on the surface, they can be stained with rosin or other substances to ensure reliable soldering. When welding electronic components, the shorter the contact time between the soldering iron and the components, the better. As long as it can be firmly soldered, it is sufficient to see that the soldering tin melts evenly at the component or solder joint (i.e., it is not a "bead like object" but flows evenly). The soldering iron should be immediately removed to allow it to cool down; It is best to ensure that the soldering point of an electronic component is completed within 3-5 seconds. In short, the specific operation requires continuous practice to continuously improve welding technology.
Conseils et méthodes pour électrique brasage fer soudage: Qu’est-ce que sont les types électriques souder fers
Extérieure chauffé électrique brasage fer à repasser
Le soudage fer tête est intérieur le chauffage noyau, aussi connu comme a régulier électrique brasage fer. Soudage ordinaire produits ne ne pas nécessite beaucoup température, et externe chauffage électrique soudure fer est utilisé. Due to the fact that the heating resistance wire is located outside the soldering iron head, most of the heat is dissipated into the external space, resulting in low heating efficiency and slow heating speed. Les avantages sont rapide chauffage, moins susceptible à humidité et fuite, basse température élévation de la poignée, et a légère sensation. Approprié pour grand soudage périodes avec grand volume et difficulté dans chauffage soudage.
Interne chauffé électrique soudure fer
The shape of the iron head used in the internal heating electric soldering iron is a hollow cylindrical shape, and the heating element is covered by the iron head, so its heat is not easily dissipated into the air. Therefore, the heat utilization efficiency is high, the preheating time is short, and the power generally does not need to be too large to meet the requirements. Generally, the internal heating power is below 50 W, and internal heating electric soldering irons of around 20-30 W are common. There are single handle and welding platform.
