Metal Laser Spot Welding Machine Portable Mini Laser Welder Jewelry Machinery Part Micro-Precision

Product Description

 

Pulse Fiber Laser Spot Welder - Product Overview

A pulse fiber laser spot welder uses short bursts of high-energy laser pulses to fuse metal surfaces precisely and cleanly. Unlike continuous laser welding, which applies a steady beam, pulse welding delivers controlled, concentrated energy in milliseconds - ideal for small parts and delicate materials. This method minimizes heat input, reducing deformation and stress, and produces clean weld seams with little to no grinding required.
 

 

What It Is & How It Works

The pulse laser spot welder emits rapid, high-power laser pulses that melt and join metal surfaces within microseconds. The burst ends before heat spreads widely, creating a small, precise weld zone. This controlled energy delivery ensures minimal thermal distortion and high repeatability, making it perfect for thin sheets, delicate assemblies, or precision components.
 

The laser spot welding gun weighs only 300g, which is not fatiguing for a long time and flexible in operation, suitable for high-precision workpiece processing.

Compact and lightweight, it can be placed on a desktop and weighs only 13kg.

No solder is required, no deformation or damage to the material after welding, and the surface is smooth and flat, without the need for secondary polishing.

Key lock system
Locks the welding machine's startup function to prevent non-operators or accidental touches from triggering welding operations.

Emergency stop button
Trigger with one click in emergency situations to immediately cut off the welding machine's power supply or welding circuit.

Grounding operate confidently in any workshop
Firmly connects the ground wire to the workpiece/grounding body, forming a complete electrical circuit

 

Key Features & Advantages

• Low Heat Input: Minimal heat-affected zone preserves material integrity and avoids warping.

• High Precision & Clean Welds: Small, neat weld spots with little slag or spatter; often no post-grind needed.

• Portable & Efficient: Compact size, can weld thin sheets (e.g. 0.2-2 mm), ideal for bench or light-duty setups.

• Energy-Efficient & Fast: Pulsed mode consumes less power than continuous welding and increases throughput for small parts.

• Suitable for Delicate Metals: Great for stainless steel, aluminum, copper alloys, and other metals where heat control is critical.

 

Typical Applications

Pulse spot welders are widely used in:

• Precision metal fabrication - medical instruments, precision hardware, small machine parts.

• Jewelry, watches, and decorative metal components - ensuring clean seams without discoloration.

• Thin-sheet assemblies - HVAC parts, automotive small panels, metal housings.

• Repair & modification tasks - on-site repair of metal parts, small welded joints, rework scenarios.

Pulsed laser spot welding vs continuous laser welding

While continuous laser welding excels at long seams and high-speed sheet or plate processing, pulse laser welding shines in applications demanding high precision, low heat distortion, and clean localized welds. Pulse systems are better for small components, thin materials, and jobs where minimal post-processing is desired. If your production involves small parts, thin sheets, or precision assemblies, a pulse fiber laser spot welder delivers higher quality, lower distortion, and cleaner finishes than continuous-beam alternatives.

FAQ

Q1. What materials can the pulse laser spot welder handle?
Works on stainless steel, carbon steel, galvanized steel, aluminum, copper, and most precision metal alloys within thin-sheet ranges.

Q2. What power options are available?
Only two models: 600 W for precision thin-sheet welding; 1200 W for higher penetration and broader small-part applications.

Q3. What is the weldable thickness range?
Stable performance from 0.2 mm to 2 mm depending on material reflectivity and the selected 600 W or 1200 W model.

Q4. Why choose pulse welding instead of continuous laser welding?
Pulse mode delivers low heat input, no deformation, clean seams, and safer operation for precision parts. Continuous mode is unsuitable for ultra-thin or heat-sensitive components.

Q5. Does the machine require external cooling or complex setup?
No. Air-cooled structure, desktop design, simple knob-control interface, and fast startup. Suitable for workshops, labs, and small manufacturing environments.
