The SUP23T laser welding head is a multifunctional handheld fiber laser welding head designed for metal welding and other laser processing applications.
One of its key advantages is the ability to switch between different processing functions and welding modes according to the application.
For laser welding, the SUP23T supports two main welding modes:
Continuous Welding
Spot Welding
In addition to welding, the SUP23T four-in-one system can also be used for laser cleaning, weld seam cleaning and laser cutting.
This makes the SUP23T a flexible solution for workshops, metal fabrication companies, equipment manufacturers and industrial users who need more than a conventional handheld laser welding head.
Continuous welding mode is designed for welding along a continuous joint.
The laser outputs energy while the operator moves the welding head along the workpiece. The scanning movement of the welding head helps distribute the laser energy across the selected welding width.
This mode is particularly suitable for:
Long weld seams
Stainless steel sheet
Carbon steel
Aluminum
Metal cabinets
Kitchen equipment
Sheet metal fabrication
Machinery components
Metal furniture
General industrial welding
Continuous welding is usually the preferred option when the customer needs to create a complete and consistent weld seam rather than individual welding points.
High Productivity
Continuous welding is well suited to long weld seams because the operator can move continuously along the joint.
Consistent Weld Appearance
With suitable laser power, scanning speed, scanning width and shielding gas, continuous welding can produce a consistent weld appearance.
Flexible Process Adjustment
The SUP23T controller allows operators to adjust important process parameters according to the material and welding application.
Suitable for Wire Feeding
The SUP23T control system provides a wire-feeding interface, making it possible to integrate a wire feeder when filler wire is required.
Unlike continuous welding, spot welding mode uses repeated laser-on and laser-off cycles.
The SUP23T allows the operator to set parameters for:
Spot welding duration
Spot welding interval
The laser therefore operates according to a repeated cycle:
Laser ON → Laser OFF → Laser ON → Laser OFF
This makes spot welding useful for applications where welding is required at specific points instead of along a completely continuous seam.
Spot welding can be considered for:
Localized welding
Intermittent joints
Positioning and fixing
Short welding points
Components requiring controlled welding cycles
Applications where continuous welding is unnecessary
The exact spot-welding parameters should be selected according to the material, thickness, joint design and laser source.
Feature | Continuous Welding | Spot Welding |
|---|---|---|
Welding principle | Continuous laser output during movement | Repeated laser ON/OFF cycles |
Best for | Long continuous seams | Individual or intermittent welding points |
Laser output | Continuous | Periodic |
Main parameters | Power, speed, width, duty cycle, frequency | Power, duration, interval and other process parameters |
Production type | Continuous welding | Intermittent welding |
Typical application | Sheet metal and long seams | Fixing, positioning and localized joints |
SUP23T support | Yes | Yes |
The key difference is the laser output pattern.
Continuous welding is designed for continuous welding movement, while spot welding controls the laser output through welding duration and interval.
Selecting the correct welding mode is only the first step.
For good laser welding results, operators also need to adjust the welding parameters according to the material and application.
The SUP23T welding interface provides several adjustable parameters.
Laser power determines the amount of laser energy delivered to the workpiece.
The SUP23T manual specifies that the peak power should not exceed the laser power configured in the system.
Scanning speed determines how quickly the laser scanning pattern moves across the welding area.
The SUP23T welding interface provides a scanning speed range of approximately:
2–6000 mm/s
However, the actual usable speed is related to the selected scanning width.
Scanning width determines the movement range of the laser beam during welding.
For the standard F150 configuration, the SUP23T manual specifies a welding scanning width of:
0–8 mm
The duty-cycle range is:
0–100%
The default setting is 100%, and the manual indicates that this normally does not need to be changed.
The welding interface provides a recommended pulse-frequency range of:
5–5000 Hz
The default value is 2000 Hz.
Actual welding parameters should always be tested and optimized according to the laser source and workpiece.
Spot welding provides additional control over the laser welding cycle.
Two important parameters are:
This determines how long the laser outputs during each welding cycle.
This determines the time between two laser output cycles.
For example:
ON → OFF → ON → OFF
By changing these two parameters, the operator can control the frequency and distribution of welding points.
According to the SUP23T manual, these settings are available in the controller's configuration interface.
This gives the operator more flexibility than simply manually triggering the laser for every welding point.
The SUP23T is not only a laser welding head.
It is designed as a multifunctional system combining several metal-processing functions.
Used for joining metal components using continuous or spot welding.
Used for removing rust, paint, oxidation and other surface contaminants, depending on the material and process parameters.
After welding, the system can be configured for weld seam cleaning to improve the appearance of the welded area.
By changing to the appropriate cutting configuration, the SUP23T can also be used for certain handheld laser cutting applications.
The product documentation identifies these multifunctional capabilities as part of the SUP23T system.
For customers comparing different handheld laser welding heads, the SUP23T offers several useful features.
One system can cover welding, cleaning, weld seam cleaning and cutting applications.
The combination of continuous welding and spot welding gives operators more flexibility for different joint designs.
Laser power, scanning speed, scanning width, duty cycle and frequency can be adjusted according to the welding process.
The control system can monitor equipment signals and display operating status and alarm information.
The SUP23T includes multiple safety-related monitoring and alarm functions. The manual states that abnormal conditions such as water-chiller, laser or air-pressure alarms can prevent laser output.
According to the SUP23T manual, the head is designed for laser sources up to 3000W.
The choice is relatively simple.
You need to weld a long seam
The joint is continuous
Production efficiency is important
You are welding sheet metal
You want a continuous weld appearance
You need to combine welding with a wire feeder
You only need individual welding points
The joint is intermittent
You need positioning or temporary fixing
You want to control laser ON/OFF time
Continuous welding is not necessary
For production applications, the final welding mode and parameters should be confirmed through material testing.
The SUP23T can be integrated into handheld fiber laser welding systems for a variety of metal-processing applications.
Suitable for applications such as kitchen equipment, cabinets, decorative metal products and industrial components.
Commonly used for metal fabrication, frames, machinery and structural components.
Laser welding can be used for lightweight metal fabrication where suitable laser power and process parameters are available.
The handheld configuration makes it convenient for welding different joint positions and workpiece geometries.
The actual welding capability depends on the laser power, material type, material thickness, joint design, shielding gas, wire feeding and process parameters.
