1. Overview, application and functional features
Laser welding is a new welding method, and also one of the important aspects of the
application of laser material processing technology. Laser welding is mainly aimed at the
welding of thin-walled materials and precision parts. The welding process belongs to the
heat conduction type, that is, the laser radiation heats the workpiece surface, and the
surface heat diffuses internally through heat conduction. By controlling the laser pulse width,
energy, peak power and repetition frequency and other parameters, the workpiece is
melted to form a specific molten pool.
Hand-held laser welding machine, with a new generation of hand-held welding head to
replace the traditional fixed light path, flexible and convenient, overcome the limitation of
work table space, work size is not unified when the situation can not automatically welding.
Mainly for large workpiece fixed position such as inside right Angle, outside right Angle,
plane weld welding.
Small heat affected area, small deformation, and welding depth, welding firm, it is a new
welding technology for long-distance welding large parts.
Laser welding can weld hard to reach parts, non-contact remote welding, with great
flexibility.
It is mainly used for laser welding of pulling metal, chassis and water tank.
Laser welding of all kinds of metal lighting frame;
Laser welding of stainless steel doors and Windows, aluminum doors and Windows;

Chapter 2:Installation instructions of hand-held welding machine
1. Water tank water injection
Open the front cover of the cabinet, inject pure water into the water injection nozzle of the
water tank, and increase the water level to the green line for initial use to ensure device
safety. The laser cooling system must meet the following requirements:
(1) The cooling water shall be distilled or purified water, and distilled water is
recommended;
(2) When starting the cooling system of the chiller for the first time, check whether there is
water leakage in the whole waterway system and joint. External water pipes must be
installed and connected as identified by the laser at a water entrance and outlet.
(3) In order to prevent the growth of microorganisms and molds in the water of the chiller
from blocking the pipeline, it is recommended to replace the cooling water once every 3-4
months to ensure the water quality of the cooling water.
(4) When the ambient temperature of the equipment is in the range of TOP ~0*€, antifreeze
must be used (please consult the after-sales department for specific models), and be
replaced every 1~2 months, and ensure that the chiller runs continuously for 24 hours to
prevent cooling water from freezing.
(5) If the laser is not used for a long time, the cooling water inside the cooling system and
the laser should be emptied, otherwise it will cause damage to the laser equipment; Empty
the water cooling system with a pressure of less than To 3MPa. Otherwise, damage will be
caused To the water cooling system.
2. Connect wires,insert argon gas tube, connecting wire feeding device
Connect one neutral wire and one live wire to the electric box. After connecting, connect the
main power cable to the lower right side of the rear cover of the device. Connect the PE
wire to the ground wire, the N wire to the neutral wire, and the L wire to the live wire.
(Please refer to actual laser power cord for details)
Connect the connection of the gas pipe connector at the lower right of the rear cover of the
equipment to the gas pipe of the argon cylinder flowmeter to ensure no air leakage.
Insert the power cord of the wire feeding device into the dragline board or distribution box,
connect the interface of the reserved line at the lower left of the rear cover of the equipment
with the wire feeding device, and assemble the wire feeding machine.
Fix the wire feed head on the II sequence holder welding head.
3. Boot sequence
① First turn on the machine air switch, in the upper left of the rear side of the machine.
②Press the power button and laser switch

you can quickly press this button to achieve protection measures).
4. Adjust the parameter
Click the menu "Process Interface" at the bottom of the main interface, click the parameter
box after setting the project according to welding product requirements, then enter a
number in the setting table of the interface and click 0K to confirm. When all Settings are
complete, click Save and import and return.
(The parameters should be adjusted according to the material, welding depth, speed and
process requirements)
Note: Welding mode is divided into continuous welding mode and spot welding mode. In continuous
mode, start the device and press the start button, the laser will emit light continuously
Until the button is released; The light time is calculated in milliseconds (1 second =1000
milliseconds). Press the button and the light output time is the pulse time, and then stop the
light output. The blowing time before the light and the blowing time after the light should be
set according to the process requirements. It is recommended that the opening of the
blowing time is not less than 50 milliseconds. The blowing time in advance and delay is
beneficial to protect the welding head, the lens and the welding seam.
Press the startup item in the interface, pick up the hand-held welding head, and the red light
indicator will appear. The welding position can be observed according to the position
indicated by the red light. Press the opening key of the hand-held welding joint to complete
the installation.
Note: the red clip is connected to the ground wire to prevent accidental light, so it must be clamped on
the metal workpiece.
5. Shutdown sequence
① After the work stops, press the laser switch on the control panel first
② Turn off the power button, emergency stop button, air switch and gas tank valve in turn
③ Place the hand-held welding head at the bracket on the top of the equipment.
6. Laser focus position and process control instructions
Focus position: minimum diameter and maximum energy of prem
It can be used for spot welding, or for low energy and minimum point
requirements
Negative defocussing position: The spot diameter is slightly larger, and the farther away
from the focal point the spot becomes larger
Suitable for continuous welding and deep melting point welding
Positive defocussing position: The spot diameter is slightly larger, and the farther away
from the focal point the spot becomes larger
Suitable for continuous welding of surface sealing welding or where the depth of fusion is
not high
Note: the positive focal length is the position where the laser flame is the largest and the
sound is the clearest.
General process control of continuous penetration welding: if the trace of slight
discoloration can be seen on the back of a single point, then better penetration welding can
be achieved in continuous welding; If the back to see obvious marks, and even can feel that
has been through, then, in continuous welding will splash, or even a deep pit. Specific to the
actual sample to adjust the focal length and energy size and waveform.
The thinner the material, the smaller the required light spot, otherwise there will be welding
through the situation.

Chapter 4、 Practical application parameters
The laser frequency is usually set to 1000 and does not need to be changed. For example,
taking 1000 as an example, if welding 2mm stainless steel , the power is set to 70%; If the
welding is 1mm, the power is set to 30 or 40%.
Note:
1. If welding 1mm stainless steel 30% of the power can be set according to the welding
speed. If the speed is fast, the weldability is good. If the welding is slow, perforation will
occur. Therefore, if the material is thin, the power should be set smaller.
2. Can not weld pure copper, no reaction, high light reflectivity, can not reach the melting
point.
