As a professional solution provider for laser processing heads, we have long been deeply engaged in optical path adaptation and on-site process debugging for laser welding. We fully understand that on-site welding is frequently plagued by various defects such as porosity, cracks, spatter and incomplete penetration. These issues not only compromise the appearance and airtightness of products but also directly reduce weld strength, leading to batch rework and cost losses.

Laser welding is a key application of laser processing technology. It utilizes the radiation energy of lasers to achieve effective welding. Its operating principle is to excite a laser-active medium (such as a mixture of CO2 and other gases, or YAG yttrium aluminum garnet crystals) in a specific manner, causing it to oscillate back and forth within a resonant cavity. This stimulates the formation of a stimulated radiation beam, which, when it contacts the workpiece, absorbs its energy. When the temperature reaches the material's melting point, welding can occur.
