1.The machine is designed for single-pendulum welding by standard specifications; however, it can be upgraded to a double-pendulum welding mode if needed.

Single and Double Pendulum Welding Machines:

Key Conclusions: A single pendulum oscillates unidirectionally along the X-axis, suitable for simple straight lines/narrow seams; a double pendulum operates on both the 

X and Y axes, enabling complex trajectories, adapting to wide seams, thick plates, and irregularly shaped parts, offering better consistency but at a higher cost.

I. Quick Overview of Key Differences

• Motion: A single pendulum oscillates only along the X-axis, resulting in a straight line; a double pendulum operates on both the X and Y axes, allowing for straight lines, 

circles, figure-eights, triangles, etc., offering greater flexibility.

• Galvanometer Configuration: A single pendulum has one galvanometer motor + lens; a double pendulum has two (multiple Y-axis motors), resulting in a more complex 

structure.

• Penetration Depth and Efficiency: A single pendulum has a more concentrated laser spot, resulting in slightly better penetration depth with wire feeding; a double pendulum 

offers more uniform energy distribution, controllable heat input, and less deformation, making it suitable for thick plates and dual-wire feeding scenarios.

• Operation and Maintenance: A single pendulum is easy to use, simple to maintain, and low in cost; a double pendulum requires programming/parameter adjustment 

capabilities, leading to higher maintenance and procurement costs. • Applicable Scenarios: Single pendulum is suitable for thin plates, simple structures, and batch standard 

parts; double pendulum is suitable for thick plates, irregularly shaped parts, wide gaps, dissimilar materials, and complex trajectories (such as fish scale patterns).

II. How to Choose the Right One 

•Choose a single pendulum: For limited budgets, simple workpieces, and a focus on easy maintenance and low cost, such as conventional thin plate linear welding and 

small batch standard parts.

• Choose a double pendulum: For complex trajectories/wide gaps/thick plates/dissimilar materials, and a focus on batch consistency and weld quality, such as pressure 

vessels, automotive structural parts, and precision irregularly shaped parts.

III. Key Parameters and Precautions

• Single pendulum: Control the amplitude, frequency, and welding speed to avoid excessive amplitude leading to shallow penetration/undercut.

• Double pendulum: Focus on adjusting the XY amplitude, frequency, and phase difference, and coordinate with wire feeding/gas parameters to adapt to complex 

trajectories and materials.

Cost Reference: The equipment and maintenance costs of double pendulum are typically 30%-50% higher than single pendulum, but the efficiency and yield advantages 

are significant under complex working conditions.

Why Choose Dual-Swing Laser Welder?

A dual-swing laser welding machine is a type of versatile welder with two swinging axes to efficiently join materials, typically metals, through precise and controlled heating. 

This design enables the double-axis laser welder to produce high-quality welds with minimal distortion and can be particularly useful for complex geometries and delicate 

components in industries such as automotive, aerospace, shipbuilding, electronics, and medical device manufacturing.

High Welding Quality

Dual-axis laser welder can ensure uniform heating and fusion of the welding area, resulting in stronger and more reliable welds.

Increased Productivity

The double-swing movement allows for faster welding speeds and reduced welding time.

Versatility

Double-swing laser welder can be used for welding a variety of materials and joint configurations.

Improved Accessibility

The swing motion enables better access to hard-to-reach areas, making it ideal for complex welding projects.

Reduced Heat Input

The controlled movement helps to minimize heat input, reducing the risk of distortion and damage to the workpiece.

The double swing welding gun has six welding modes to choose from. Different welding modes can make the welding surface more beautiful and present different welding 

process patterns. Multi-mode welding has better filling effect and stronger welding than single horizontal line welding.

2.This machine can function as a simple welding machine, a simple cleaning machine, a three-in-one (welding, cutting, cleaning) machine, or a four-in-one (welding, cutting, 

cleaning, and cleaning weld seams) machine.

The following are the different laser heads in four different modes of the four-in-one design:

Four-in-one spare parts:

3.The machine comes standard with one roll of carbon steel wire, but customers can choose to purchase it locally according to their needs.

4.Protective goggles are included with the machine; customers can choose to purchase several pairs as spares, or they can buy them locally.

Handheld Fiber Laser Welding Projects

Laser Welder vs MMA Welder vs MIG Welder vs TIG Welder

MMA Welder (Manual Metal Arc Welder), also known as MMAW or SMAW (Shielded Metal Arc Welder), features with excessive weld spatter, low filler metal utilization, and 

the need to frequently remove slag and replace rods, resulting in extremely slow speed and low production efficiency. In addition, the higher reliance on rods requires 

welders with operating skills and experience.

MIG Welder (Metal Inert Gas Welder) features with high wire consumption and heat input, making thin metal sheets easy to deform and burn through, medium-thick metal 

plates require grooves, resulting in rough welds that require subsequent polishing.

TIG Welder (Tungsten Inert Gas Welder) features with shallow penetration depth and large melting width, which makes it only able to weld thin sheet metals, and results in 

large deformation. Moreover, high current will cause the tungsten electrode to melt and evaporate, and manual wire filling is difficult and inefficient.

Handheld Laser Welder features with environmentally friendly and pollution-free, deep penetration, high speed, smooth and clean welds with small deformation, which 

reduces the follow-up grinding process, resulting in straight and uniform welds without professionals.

MMA, TIG, and MIG welding machines require experienced welders, and starters with extensive training and research, while a handheld laser welder is intuitive, concise, 

user friendly, easy to use, which is preset with mostly used parameters, and you can customize the setting and save what you need, a beginner can easily get started after 

a few hours of learning.

The speed of MMA, TIG, and MIG welders typically does not exceed 1 centimeter per second, while the speed of handheld laser welders can reach 2-10 centimeters per 

second, and its efficiency is 2-10 times that of traditional manual arc welders. In addition, the handheld laser welder can easily weld various types of metals, including 

ordinary steel (such as carbon steel, stainless steel, galvanized steel), aluminum alloy, and brass, and the weld penetration depth (WPD) can reach 8mm for steel, and 

6mm for aluminum alloy or brass.

6.How to use a handheld laser welding machine?

Turn on the power and turn on the laser welder, and observe whether the water temperature is appropriate (usually set at around 21°C, it can be adjusted appropriately 

between 20 and 25°C according to the situation. Antifreeze needs to be added when the weather is cold, and antifreeze needs to be added when the temperature rises. 

Replace it with pure water), then turn on the laser switch, select the welding mode according to the metal parts to be welded, set the required parameters and pick up 

the handheld laser gun and start welding. During working, do not look directly into the laser beam with your eyes and do not touch it with your hands to avoid injury. If 

there is an emergency such as water leakage or abnormal sound, press the "emergency stop" switch immediately. After working, turn off all equipments in use and the 

main power switch in turn.
