In metal processing (steel, aluminum alloy, titanium alloy, etc.), laser welding machines range from $50,000 to millions. How to choose the right equipment based on demand? This article explains the core differences in "three sentences" and includes a selection decision checklist.
I. Entry-level ($50,000 - $150,000): " Essential model " for thin metal plate welding
What can it weld:
Materials: ≤1mm stainless steel plate, low-carbon steel plate, aluminum alloy foil
Scenarios: Metal distribution box splicing, car radiator sealing welding, small-batch metal parts spot welding
Key features:
✓ Pulsed laser below 300W, suitable for "surface welding" without penetration
✓ Manual focusing, red light positioning, 30 minutes to get started
✓ Argon protection (purity ≥99.99%) required for aluminum welding
Watch out for pitfalls:
▸ Welding galvanized steel can damage mirrors (need to clean every 2 hours)
▸ High reflectivity of copper alloy, pass rate only 60%-70%
II. Industrial grade ($200,000 - $1 million): " Main force for mass production " of medium - thick metal parts
What can it weld:
Materials: 1-10mm carbon steel, 3-8mm aluminum alloy, 5-6mm titanium alloy
Scenarios: Automotive chassis structural parts, pressure vessel circumferential seams, agricultural machinery wear - resistant parts overlay welding
Technical upgrades:
✓ 500-2000W continuous laser, deep penetration welding 5-12mm (e.g., one - time welding through 8mm carbon steel)
✓ Standard weld seam tracker (±0.05mm accuracy), automatically compensates for workpiece errors
Aluminum welding with dual - gas protection, titanium alloy can select front and back drag hood
Efficiency comparison:
▸ Welding 4mm aluminum alloy, speed 6m/min (3 times faster than TIG welding)
▸ Comprehensive energy consumption is 40% lower than traditional processes
III. High-end customization ($1 million +): " Power tool for tackling tough jobs " in metal cutting - edge manufacturing
What can it weld:
Materials:＞10mm titanium alloy, dissimilar metals (e.g., copper - steel, aluminum - steel)
Scenarios: Aerospace structural parts, new energy battery packs, nuclear power pipelines
Cutting - edge configurations:
✓ Ultra - high - power laser above 4000W, supports 20mm carbon steel welding without beveling
✓ Laser - arc hybrid welding, dissimilar metal fusion strength≥250MPa
✓ Vacuum welding chamber (≤10⁻⊃3;Pa), titanium alloy welding without oxidation
Industry value:
▸ Automotive body - in - white welding cycle 90 seconds per unit, efficiency increased by 5 times
▸ Weld seam fatigue life of aviation parts increased by 3 times, passed airworthiness certification
IV. Key points to avoid pitfalls in metal welding
Power test: Ask manufacturers to weld 1mm steel plate on site, 300W equipment should weld through within 8 seconds
Gas path design: Dual - gas path (front and back protection) must be used for aluminum welding
Process verification: Test weld seam strength with samples (e.g., tensile strength≥80% of base material)
V. Domestic brand recommendation: PDKJ series welders
Industrial - grade equipment: Supports welding of carbon steel / aluminum alloy / titanium alloy / stainless steel and other multi - materials
Core advantages: Modular design (upgradable to robot), free process debugging, 7×24 hour after - sales service
