The cutting setting of welding head of the super powerful Weiye I. Copper nozzle Use a cutting copper nozzle (We recommend that copper nozzle 1.5 or more is enough.) II. craft Unlike welding, cutting spots has no width. Therefore, the scan width must be set to 0, that is, the red light is a point. Sweep speed: Ignore this parameter and feel free to do so Scan width: 0 Peak power: The reference data recommends to be full power cutting, which is subject to actual conditions. Duty Cycle: reference data is 100. Pulse frequency: reference data is 1000. After setting the parameters, if you import and go back, and you can see this process on the left side of the home page. As to the focus, it is recommended to use negative focus (because it directly affects the cutting effect) III. The center point of the red light Be sure to make sure that the red light comes out of the center of the copper spout completely, otherwise it may burn the brass spout. Generally use hardware to make adjustments, that is, to adjust the tail motor. Adjustment method reference: Adjustment of red light IV. Cutting workpieces The requirements of focus: if you use retro-focus, the sluggish that it generates is less relatively. The requirements of valve (using the reduced valves made of oxygen or argon pressure) The requirements of gas: If there is a requirement for the cutting surface, it is recommended to use nitrogen gas (be sure the weight of nitrogen is greater than 6 kg) which means to compare with the cutting surface, it will be whitish relatively. If the thickness of the cut is required, please use oxygen or air to cut, and it will be blackened compares with the cutting surface. Cutting thickness: 3 mm or less is the best. Hand speed is maintained evenly when cutting.

This article applies to change welding into cleaning. Process settings ①Cleaning process Scanning frequency: the swing speed of the motor whose range is 10-100Hz, and it is recommended to set 50. Scanning width: the scanning width of the light plate whose range is 0-150mm, and it is recommended to set 150. Duty Cycle: default data is 100%. Pulse frequency: default data is 2000. After setting the parameters, if you import and go back, and you can see this process on the left side of the home page. ②Be sure to remove the graduated tube and locking part of the welding gun ③Confirmation of focus By the scanning of back and forth, near and far, the focus is when the sound is the largest and the spark is the largest. At this time the cleaning should be carried out according to this distance, and in this time the energy is the strongest. （Generally, the distance from the tip to the plate is about 30 cm and the energy is the strongest) ④The use of gases It is recommended to use air, and 2-3 kg is enough. If you are going to use other inert gases (argon/nitrogen), be sure the flow rate is more than 20.

The version number of the panel monitoring page corresponding to spot welding function is: 330 or more (inclusive) 1. How to use spot welding function 1.1 Play spot weld mode on the first page 1.2 Set the type of spot welding selected inside (fish scales/intermittent). 1.3 Set reasonable lasting time and interval time of spot welding Two. Parameters of spot weld types and debugging First of all, use the way of continuously welding to debug the process. And then use spot welding function to select the spot weld type 2.1 Fish scale welding mode （In this mode, only the laser is turned off when in the intermittent, and other settings such as switching on or switching off light time do not affect and do not take effect.) Only to set the spot welding duration and interval time can produce a fish scale welding effect, and the minimum can be set is 1ms.) For an example Spot welding duration: 150ms（this parameter affects the size of the streak of the weld.) Spot welding interval time: 50ms（this parameter affects the interval between two textures.) 2.2 Intermittent welding mode （In this mode, please turn off the laser, the shielding gas, and stop wire feeding when in the intermittent.) The other parameters such as the time of switching on or off are mainly used for fix length welding.) By setting the spot weld duration to change the weld length, and the spot weld interval time can be set higher. For an example Spot welding duration: 1000ms（this parameter affects the welding length, that is, the time of light flowed up) Spot welding interval time: 5000ms（this parameter can be fixed, and the default is 5000) Please pay attention that in this mode, it needs to be artificially judged whether the wire is broken or not, and the wire needs to be lifted up in time. As it has shown in the picture:

Follow these principles when welding ① The thicker the plate, the thicker the welding wire； the greater the power, and the slower the wire feeding speed ② The lower the power, the whiter the welding surface. The greater the power, the weld seam will change from color to black, and the single-sided form will be formed at this time. ③ The thickness and fineness of the welding wire should not be larger than the plate thickness instead of closing to the plate thickness. The welding wire will also affect the fullness of the weld. ④ The thinner the weld wire, the lower the scanning width. Affected by different brands of lasers, the following processes use the following laser to do proofing tests. But it is for reference only, and need to be fine-tuned appropriately when using ①Tottenham Hotspur / Chuangxin / Jept ②Argon I. Carbon steel/galvanized sheet Note: Affected by the zinc layer of the galvanized sheet, the power of the galvanized sheet can be appropriately reduced. II. stainless steel Stainless steel power of 3000W can have a reference to carbon steel III. aluminium The aluminum process refers to stainless steel process, the power can only be increased by 20%-30%. What’s more, there are also differences in the focus, which need to be adjusted manually. Reference:  0.5MM stainless steel internal corner welding The scanning speed of 0.8 stainless steel wire is 350, the scanning width of it is 2, the peak power of it is 350, the duty cycle of it is 100, and the frequency is 2000. The light penetrates the plate, and the amount of deformation is very large, so we taka action of reducing the power. The scanning speed of 0.8 stainless steel wire is 350, the scanning width of it is 2, the peak power of it is 260, the duty cycle of it is 100, and the frequency is 2000. The amount of deformation has been reduced, but it is still easy to be burnt when the light starts flowing out, that’s the reason why we continue to reduce the power in the process. The scanning speed of 0.8 stainless steel wire is 350, the scanning width of it is 2, the peak power is 200, the duty cycle of it is 100 and the frequency is 2000. The effect is as follows ①. When you increase the width to 3 is as it shown in figure ②.

Why do stomata appear？ 1.1 The inside of the laser welded hole is in an unstable vibration state, and the flow of the hole and the molten pool is very intense. The metal vapor inside the hole erupts outwards and leads to the steam vortex formed at the opening of the hole, which rolls the protective gas (Ar) into the bottom of the hole, and with the hole moves forward, these protective gases will enter the molten pool in the form of bubbles. Due to the extremely low solubility of Ar and the rapid cooling rate of laser welding, the bubbles are left in the weld seam before they can escape to form stomata. What’s more, it was caused by the poor protection during the welding process that nitrogen invades the molten pool from the outside, and the solubility of nitrogen in liquid iron is very different from the solubility of nitrogen in solid iron. Therefore in the cooling and solidification of the metal, the solubility of nitrogen decreases with the decrease of temperature when the molten pool metal is cooled to the beginning of crystallization can lead to a large sudden decrease in solubility. At this time a large amount of gas precipitates will form bubbles. If the floating rate of the bubbles is less than the metal crystallization rate, the pores are generated. The way of laser fusion welding suppresses porosity 1. Suppress welding pores by pre-welding surface treatment Pre-welding surface treatment is an effective method to control the metallurgical pores of aluminum alloy laser welds. The surface treatment methods can be divided into physical mechanical cleaning and chemical cleaning usually. After comparison, taking the chemical method to deal with the surface of the test board (metal cleaner cleaning - washing - alkali washing - washing - washing - washing - drying) is the best. Among them, the alkali wash is removed from the surface thickness of the material with an aqueous solution of 25% NaOH (sodium hydroxide), and the pickling is carried out with a 20% HNO3 (nitric acid) + 2% HF (hydrogen fluoride) aqueous solution to neutralize the residual lye. After the surface treatment of the test plate, the welding is carried out within 24 hours, and the assembly before welding is assembled and wiped with anhydrous alcohol when the test plate is installed for a long time after the test plate treatment. 2. Inhibit welding pores by welding process parameters The formation of weld porosity is not only related to the quality of weldment surface treatment, but also related to welding process parameters. The influence of welding parameters on the pores of the weld is mainly reflected in the penetration of the weld, that is, the influence of the back width ratio of the weld on the pores. By testing we can know that it can be seen that when the weld back width ratio R is > 0.6, the concentrated distribution of the chain pores in the weld can be effectively improved. And when the back width ratio R is > 0.8, the existence of atmospheric pores in the weld...

This article applies to professional cleaning systems ①Cleaning process Scanning frequency: the swing speed of the motor whose range is 10-100Hz, and it is recommended to set 80 Scanning width: The scanning width of the spot whose range is 0-300mm, which should be selected in the system settings according to the specifications of the focusing mirror actually used Peak power: to be regarded as the defaults to the maximum power of the laser generally Duty Cycle: the default data is 100% Pulse frequency: the default data is 2000 After setting the parameters, if you import and go back, and you can see this process on the left side of the home page ②Confirmation of focus Through the scanning of back and forth, near and far, the focus is when the sound is the largest and the spark is the largest. At that time, the cleaning should be carried out according to this distance because the energy is the strongest Depending on the difference of the use of focusing, the following is a reference F400 focus ( the distance from the tip to the plate is about 35-40 cm or so when the energy is the strongest generally) F800 focus (the distance from the tip to the plate is about 65-75 cm or so when the energy is the strongest generally) ③The use of gases Gas selection for cleaning: air should be not less than 5 kg, oil-free and water-free should be filtered or other inert gases should be used when it is above three levels When cleaning, be sure to keep the distance from the tip to the plate stable and the hand speed be even.
