Advantages and disadvantages of handheld laser welding machines

Advantages and disadvantages of handheld laser welding machines

✅ ‌Core Advantages‌

‌High Precision and Low Thermal Impact‌

The laser focus diameter is small (0.1-2mm), and the thermal deformation is extremely low, which is suitable for precision welding (such as thin plates and tiny parts).

The heat-affected zone is reduced by 50%-70% compared with traditional welding, reducing material performance damage.

‌High Efficiency and Flexibility‌

The welding speed is 5-10 meters/minute, and the efficiency is 3-5 times that of argon arc welding.

The angle can be adjusted 360° to adapt to complex structures (such as curved surfaces and special-shaped parts) without repeated positioning.

‌Multi-material Compatibility‌

Supports stainless steel/carbon steel (0.5-6mm), aluminum alloy (0.8-4mm), etc., and the qualified rate of titanium alloy welding exceeds 95%.

The new model in 2025 already supports copper welding (needs to be matched with a blue light laser module).

‌Environmental protection and energy saving‌

Energy consumption is 30%-50% lower than that of traditional welding, with no smoke/exhaust gas emissions, and in line with ISO 14064 standards.

⚠️ ‌Main disadvantages‌

‌High cost investment‌

The unit price of the equipment is 150,000-500,000 yuan (market price in 2025), the life of the fiber laser is about 60,000-80,000 hours, and the replacement cost exceeds 30,000 yuan.

‌Strict process requirements‌

The workpiece assembly gap must be ≤0.2mm, and the misalignment must be ≤0.1mm, otherwise pores/unfused defects are prone to occur.

A constant temperature and humidity environment is required (recommended temperature 5-40℃, humidity ≤60%).

‌High threshold for operation‌

Some countries require a Level 4 laser operation certificate

‌Safety risks‌

Laser radiation must meet the CLASS 1 protection standard, welding sputtering temperature is high, and a full set of protective equipment is required.

‌Applicable scenario recommendations‌

‌Recommended scenarios‌

Auto parts (battery tray/motor housing)

Kitchen and bathroom stainless steel products (sinks/pipes)

3C electronic products (mobile phone middle frame/hinge)

‌Caution scenarios‌

Carbon steel heavy structure with thickness > 8mm

Highly reflective materials (bare copper/polished aluminum)

Porous/honeycomb structure (uneven heat dissipation)
