How to choose the most suitable laser welding machine
How to choose the most suitable laser welding machine?
Fiber Laser welding machine has become a popular choice in the industrial manufacturing field due to its advantages of high precision, high efficiency, and non-contact processing. However, when faced with a wide variety of laser welding machine on the market, understanding the following points makes it easy to choose the most suitable model based on actual needs
Core parameter 1: Single-axis galvonometer vs dual-axis galvanometer laser welding head
The galvometer mode of laser welding head directly affects the welding quality and applicable scenarios, and needs to be selected based on processing requirements.
1. Single-axis galvonometer laser welding head
Working principle: The welding head swings regularly along a single direction (usually the X or Y axis) to form a linear weld seam.
Advantages:
*Low cost: Simple structure, low equipment procurement and maintenance costs.
*Fast speed: suitable for thin plate welding (such as 0.5-3mm stainless steel), high efficiency.
*Strong stability: simple mechanical structure, low failure rate.
Applicable scenarios:
-Straight line welds and welding of simple geometric shapes (such as boxes and frames).
-Small and medium-sized enterprises that do not have high requirements for weld aesthetics and pursue cost-effectiveness.
2. Dual-axis galvanometer laser welding head
Working principle: The welding head swings synchronously in both the X-axis and Y-axis directions, forming complex trajectories such as circular and spiral shapes.
Advantages:
*High weld quality: flexible swing path, more uniform melt pool, reduced porosity and cracks.
*Strong adaptability: Can weld irregular workpieces (such as curved surfaces, fillet welds, and lap joints).
*Excellent aspect ratio: suitable for welding thick plates (such as 5mm or more), with stronger penetration.
*Has 7 welding modes as following picture
Applicable scenarios:
-Automotive components (battery trays, motor housings), aerospace precision parts.
-High end manufacturing fields with high requirements for weld strength and sealing.
Purchase suggestion:
Priority single pendulum: limited budget, simple product structure, mainly based on thin plates.
Must choose double pendulum: welding complex surfaces, thick plate materials, or pursuing ultra-high yield.
Other key purchasing factors
1. Power selection principle
Thin plate (<3mm): 1000W-1500W (balancing speed and cost).
Medium thick plate (3-8mm): 2000W-4000W (requires double swing welding head).
Ultra thick plate (>8mm): 6000W and above+composite welding technology.
2. Automation requirements
Basic model: Handheld welding+semi-automatic welding, suitable for small batches and multiple varieties.
Advanced version: Robot integration+visual positioning, suitable for continuous operation on automotive production lines.
3. Function selection
With the continuous updating of technology, it can be divided into the following three types
*Simple welding function
*Four in one function (welding, cutting, cleaning, and weld cleaning functions)

*Five in one function (welding, cutting, cleaning, and welding bead cleaning, battery energy storage welding)

4. Selection of wire feeder
Thin plate: single wire feeder
Medium thick plate: Dual wire feeder
Ultra thick plate: Four wire feeding machine
Summary: A one-step purchasing solution
1. Clarify requirements: Sort out product materials, thickness, weld seam form, and production capacity requirements.
2. Pendulum selection: Simple workpiece single pendulum, complex surface must choose double pendulum.
3. Power matching: Refer to material thickness and reserve 20% power margin to meet upgrade requirements.
Case reference:
1. A new energy vehicle battery tray manufacturer has increased its yield from 85% to 98% by using a 6000W fiber laser and dual swing welding head.
2. A certain household appliance enterprise purchased 2000W single pendulum equipment and welded 1mm stainless steel shells, which increased production efficiency by three times.
