Can Laser Cleaning Replace Traditional Processes? Field Test for Precision Spot Welding Industry

Workpiece degreasing, rust removal and welding spot cleaning are essential procedures in precision hardware and new energy tab processing. Plenty of manufacturers are curious about whether laser precision cleaning machines can replace traditional pickling and manual polishing, especially factories equipped with laser precision spot welders pay close attention to the linkage effect between two devices. As a senior operation staff of Shenzhen Jianyi Automation serving frontline clients, I make an objective analysis based on abundant sample test and mass production data.

1. Traditional Cleaning Methods Fail to Meet Precision Machining Demands

Precision spot welding sets strict standards for workpiece surface flatness and welding joint strength. Pickling alters surface chemical composition and leads to cold solder risks in follow-up spot welding. Manual polishing relies heavily on workers’ experience, causing inconsistent cleaning results for batch workpieces and scrapping due to excessive polishing. Tightening environmental regulations also raise costs of waste liquid treatment systems for small and medium processing factories, pushing them to seek alternative solutions.

2. Three Major Strengths of Laser Cleaning for Spot Welding Processing

First, non-contact processing avoids mechanical pressure, preventing deformation of thin workpieces and ultra-thin tabs after spot welding. Second, adjustable cleaning precision allows spot decontamination only on welding areas while keeping other workpiece surfaces intact. Third, low daily operation cost: only lens cleaning maintenance is needed without recurring consumable expenses, cost advantages become more prominent with long-term mass production.

We provide integrated solutions for multiple power battery component manufacturers: after tab spot welding by laser spot welders, laser cleaning machines remove welding oxide stains on production lines, realizing automated procedure connection and cutting manual work greatly.

3. Full-Process Technical Support From Jianyi Automation

Different from suppliers only selling hardware equipment, our strength lies in process matching. After clients send workpieces, our technical team tests proper laser power and processing speed matching existing laser precision spot welding parameters and delivers detailed process reports. Engineers conduct on-site commissioning and operator training after delivery, and offer remote parameter adjustment when clients update product specifications later.

4. Factories Suitable for Priority Upgrade of Laser Cleaning

Enterprises focusing on high-value precision spot welding with strict yield requirements, and processing factories facing strict environmental restrictions to eliminate pickling procedures gain most benefits from laser cleaning. Factories doing low-end rough processing without strict cleaning precision demands can conduct free sample tests first before making decisions
