Weld surface cleaning is one of the classic applications of industrial laser cleaning. It is widely used in fields such as automobiles, shipbuilding, and precision tool manufacturing. It can clean steel, stainless steel, aluminum, iron and other materials without damaging the base material, and does not affect the welding effect of the product. In addition to metal cleaning applications, laser cleaning machines can also remove oxide layers, primers, oils, hydrates, etc.
Advantages of laser cleaning weld beads:
The traditional cleaning method is to use strong acidic solutions for cleaning, which will corrode the product and produce substances harmful to the environment. And laser cleaning uses a non-contact, precise processing method without using any chemical agents, effectively solving this environmental problem. In addition, laser cleaning also has other significant advantages:
1. Damage-Free Cleaning: Laser cleaning is a non-contact process and does not require direct contact with the weld surface, thus avoiding damage or deformation of the workpiece.
2. Focused Precise Cleaning: Laser cleaning can accurately control the cleaning area and cleaning depth, and can adjust parameters according to needs, and is suitable for welds of various complex shapes.
3. Environmental Friendly: The laser cleaning process does not require the use of chemical solvents or other cleaning agents, does not produce any toxic waste, and meets environmental protection requirements.
4. Good Cleaning Effect: The laser energy is high and can completely remove oxides, welding slag and other dirt produced during the welding process to ensure that the weld surface is clean.
5. Decrease Costs for Maintenance: Compared with traditional cleaning methods, laser cleaning can save manpower and materials in long-term operation and is cost-effective.
Laser cleaning plays a unique auxiliary role in the field of industrial welding. The laser cleaning machine can remove lubricants, ferrous metals and non-ferrous metals from metal, assist the laser welding machine to complete smooth and non-porous high-quality welds, and effectively improve the stability and appearance quality of the welds.
Pretreatment Before Welding
1. Before welding, laser cleaning of debris, dirt, oil stains or other pollutants on the material can ensure the cleanliness and quality of the welding surface, thereby improving the strength and sealing of the welded joint, avoiding welding defects in the weld, and improving the welding efficiency and quality.
Cleaning After Welding
2. Generally speaking, after the welding process is completed, gray-black or yellow oxides or welding slag will remain in the weld. In order not to affect the performance and appearance of the product and reduce subsequent surface treatment processes, we need to clean the welds to ensure the quality and strength of the welds and save production costs and time.
Weld Bead Cleaning of Old Workpieces
3. After welding, the welds will have rust marks due to the influence of time, sun, rain and other external factors, which will affect the performance and appearance. Laser cleaning can remove rust in time and continue to play the effective role of products and structural components.
In recent years, MACTRON has focused on customers’ processing requirements and produced a variety of machines that meet European standards, including portable handheld laser cleaning machines and high-power pulse laser cleaning machines. As industries continue to prioritize environmental sustainability and cost-effectiveness, laser cleaning stands out as a forward-looking and environmentally friendly solution.
