Handheld laser welding, with its high efficiency and portability, has long been a powerful tool for sheet metal processing, hardware manufacturing, and other industries. However, many customers report encountering minor issues when first using it, often due to a lack of mastery of the techniques: issues such as porosity in the weld, lack of penetration, and misaligned red light. However, to minimize downtime, if you experience any of the following issues, please don't rush to report a repair. It may simply be a "false fault." No need to wait for a professional repair person to come, you can easily fix the problem yourself, saving time and effort.

(1)Causes of black explosion points When the laser passes through the stain, a violent oxidation reaction will occur to form gas, which will directly affect the stability of the molten pool keyhole and form a black explosion point. Specifically, the molten pool keyhole is abnormally closed, resulting in insufficient melting depth, insufficient melting width, unmelted surface or direct penetration of the parent material, which requires metallographic cutting to assist in judgment.
