KEMPSON Laser Welder Protective Lens is designed for regular maintenance of handheld laser welding machines. The eccentric rotating structure improves lens utilization and reduces replacement frequency during welding operations.
Protective lens and focus lens are both important optical components in a laser welding gun, but they have different functions during welding operation.
| Lens Type | Main Function | Working Role |
| Protective Lens | Protects the internal optical system from welding spatter, dust, and heat | Installed in front of the optical path to reduce contamination and damage to the focus lens |
| Focus Lens | Focuses the laser beam into the welding position | Controls the laser spot size and affects welding penetration and process stability |
The protective lens is a consumable protection component, while the focus lens is a precision optical component responsible for laser beam focusing. Regular inspection and replacement of the protective lens helps protect the focus lens and maintain stable welding quality.
The protective lens should be checked and replaced when welding performance changes or visible contamination appears. Common signs include unstable laser output, reduced welding penetration, black marks on the lens surface, or abnormal lens temperature.
KEMPSON supplies Laser Welder Protective Lens for handheld fiber laser welding machines from 1000W to 6000W. The lens kit includes 5 protective lenses and 1 focus lens, suitable for regular maintenance and lens replacement of laser welding equipment.
The protective lens uses an eccentric rotating structure. When one area of the lens is contaminated, the lens can be rotated to another usable position. One lens can be reused 3-4 times, helping reduce lens replacement and operating costs.
KEMPSON provides laser welding optical accessories with stable quality and flexible supply options. Contact us for protective lens selection, compatible models, and bulk orders.

Laser beam welding is an advanced fusion welding process that uses a focused laser beam as a heat source to melt and join materials. It provides high welding speed, low heat input, small deformation, and precise control, making it widely used in automotive, aerospace, electronics, battery manufacturing, and precision industries.
This article explains whether laser welding is strong, covering weld strength, penetration depth, joint durability, influencing factors, and comparisons with traditional welding methods. It also introduces suitable materials and industrial applications to help users understand if laser welding meets their production requirements.
Laser welding is widely known for its ability to create strong, precise welds with minimal heat input. One of the most common questions is whether filler metal is required during the process. In many applications, laser welding can be performed without filler wire by directly fusing the base materials. However, filler metal becomes important when welding thicker materials, bridging joint gaps, preventing cracking, or joining dissimilar metals. This guide explains how autogenous laser welding works, when filler wire is necessary, whether wobble welding can replace filler metal, and how to choose between wire and powder fillers for different applications.
This guide explores the key features, benefits, applications, and buying considerations of modern Fiber Laser Tube Cutting Machine systems. You will also learn how to compare different models, evaluate automation options, and find the Best Tube Laser Cutting Machine For Sale for metal fabrication, steel processing, and industrial manufacturing needs. By understanding performance factors such as power, precision, tube capacity, and software capabilities, businesses can make a more informed investment decision and choose a reliable Tube Laser Cutting Machine Supplier that meets their long-term production goals.
