8.6 Multi-layer multi-bead process package
1 Function introduction
1.1 Applicable scenarios
Multi-layer multi-bead welding is mainly applicable to deep and wide weld joints. When welding a weld joint with a weld leg size greater than 10mm, if multi-layer welding is used, because the surface of the weld joint is wide and the slope is large, the molten metal is easy to sag, and the heat input at the welding position is too large. Therefore, in actual production, multi-layer multi-bead welding is used, and each weld joint adopts welding swing.
1.2 Function principle
Multi-layer multi-bead welding simplifies the track which needs to be manually instructed for many times. By filling in the offset value of each layer of weld bead relative to the initial weld bead, a complete welding track is automatically generated by setting at one time, thus to achieve the welding effect of filling the weld joint accurately. At present, only X, Y, and Z offsets in world coordinates are supported. If the welding track brings a workbench, they are the offsets in the workbench direction.
1.3 Main characteristics
* Easy programming, only needing one basic track programming;
*Strong adaptability, being able to separately set welding swing parameters among welding process parameters of each welding track;
* High compatibility, being able to separately set the offset (X,Y,Z) and welding gun angle (θ) of each welding track;
* Being able to be nested with other functions.
2 Settings screen introduction
2.1 Start welding process
(With digital communication Megmeet welder as an example, the operation is shown in the images below)
When the knob switch is in the Stop mode/state, enter "Settings", select "Product Settings", and then select "craft Setting" → Select "weldingProcess" for Technology type → power off and restart. Enter "CAN Settings" in "Communication Configs", and set "CAN use to" to "Welder", "ID config" to "1", "Baud Setting" to "125kbps", "Manufacturer" to "Megmeet", "Model" to "Artsen II" → power off and restart. Return to "Settings", select "Product Settings", select "craft Setting" → tick digital welder → digital welder setting is finished
(Remark: For other welding machine settings, please refer to BORUNTE HUACHENG Drive and Control Integrated Welding Process Operation Manual V1.1)
2.2 Set Welding Params and Welding Swing
(Remark: For detailed welding settings, please refer to BORUNTE HUACHENG Drive and Control Integrated Welding Process Operation Manual V1.1)
2.3 Multiple Welding Para screen
When the knob switch is in manual mode, select Manual operation → Multiple Welding Para
Function explanation:
① file number area: Used to store the welding bead welding parameters of multiple different products, with a set range of 1~100; if beyond, "Welding file information already full!" will be prompted. Click New file number to name and create a new file number; to delete a file number, switch to the file number to delete in the file number area and click Delete file number. File number replication is supported.
② welding bead area: Used to store the welding parameters of each welding bead of a file number, with a set range of 1~100; if beyond, "Welding bead already max!" will be prompted. After clicking Add welding bead, the parameters of the currently selected welding bead will be copied into a new welding bead at the end. After clicking Insert welding bead, the parameters of the currently selected welding bead will be copied into a new welding bead and inserted behind the selected welding bead
③ welding current: Set the welder output current, and ensure that the current priority value is higher than the current on the Welding Params page
④ welding voltage: Set the welder output voltage, and ensure that the voltage priority value is higher than the voltage on the Welding Params page
⑤ arcing voltage: Set the welding arcing voltage, and ensure that the arcing voltage priority value is higher than the arcing voltage on the Welding Params page
⑥ speed: welding speed
⑦ swing amplitude: Distance of unilateral swing, and ensure that the swing amplitude priority value is higher than the swing amplitude on the Welding Swing page
⑧ swing frequency: number of swing times per second, and ensure that the swing frequency priority value is higher than the swing frequency on the Welding Swing page
⑨ _xoffset (ΔX): offset in X direction in world coordinates, unit: mm; if it brings a workbench, it is the offset of workbench in X direction _yoffset (ΔY): offset in Y direction in world coordinates, unit: mm; if it brings a workbench, it is the offset of workbench in Y direction _zoffset (ΔZ): offset in Z direction in world coordinates, unit: mm; if it brings a workbench, it is the offset of workbench in Z direction
⑩ _θoffset (Δθ): Offset of welding angle of welding gun, unit: °. θ is the included angle between the current welding gun and the tool coordinate Y direction. If θ is positive, the welding gun will offset towards the included angle increasing direction; if θ is negative, the welding gun will offset towards the included angle decreasing direction Remark: After adding a file number and modifying a welding bead, click "Save", which can automatically sort the welding bead numbers. Select file number 1, click Setting/Try Run Page to switch to multi-layer multi-bead second parameter page, on which you can uniformly view the parameters of each welding bead in each file number, carry out program extraction and track trial run.
Remark: The general program formats are safety point, preparation point A, preparation point B, end point and leave point. From preparation point A to preparation point B, it is a guiding line in the same direction as the offset track; from preparation point B to end point, it is the offset welding track. Details will be given later.
Function explanation:
① Search action (welding track search): This page is used for track search and post-offset track trial run
② choose search type:
（3）Auto Search: All the track points of the selected track type in the search range will be automatically searched, and only the offset track start point, e.g. preparation point B and end point A in the image above, will be automatically stored on the Try Run Area page
（4）Search by Manual: The track searched will not be automatically stored on the Try Run Area page, and it needs to manually select the program line and click Add and Try Run
③ choose search Action: choose Search All or Custom as shown in the image below
④ Search: Search the track based on the currently set criteria
⑤ clearSearch: Clear all tracks that have been searched
⑥ Add and Try Run: Manually store the program into the Try Run Area page Remark: This page can also be used to add, delete, modify and save welding beads Manually add and try running safety point, preparation point A, preparation point B, end point and leave point, and click Try Run Area
Function explanation:
① Try Run Area: Click to switch to the Try Run Area page
② Signal Try Run: After ticked, select the program line, click Try Run, and stop after running the program line
③ All Try Run: After ticked, click Try Run, and stop after running all track lines
④ the weld info: After clicking the drop-down options, it can switch the welding beads in each file number, and will run according to the different offset parameters of each welding bead during trial run
⑤ Remove: Remove this point from Try Run List
⑥ move up: Move the selected trail run program line up
⑦ move down: Move the selected trial run program line down
⑧ Setting/Try Run Page: switch back and forth between "Multiple Welding Para" page and the "Try Run Area" page
⑨ Clear Try Run List: Clear all try run list points
Remark: During trial run, all tracks in Try Run List will be offset according to the welding bead parameters in the file number, including safety point, preparation point A, preparation point B, end point, and leave point. In the actual welding, only the welding track, i.e. from preparation point B to end point, is offset; if you only need the latter, please set "choose search type" to Auto Search.
