How to reduce the temperature of welding robot molten pool when the temperature is too high
1. Angle
When the angle between the electrode and the welding direction is 90 degrees, the arc is concentrated, the temperature of the molten pool is high, the angle is small, the arc is scattered, and the temperature of the molten pool is low. For example, the angle of the electrode is 50-70 degrees, which reduces the temperature of the molten pool and avoids overlap or rising on the back. For another example, after the bottom layer of 12mm plate vertical welding is replaced with welding rod, the welding rod angle of 90-95 degrees is used during the joint, so that the temperature of the molten pool can be rapidly increased, the molten hole can be opened smoothly, the back surface is formed more smoothly, and the concave phenomenon of the joint point is effectively controlled.
2. Time
Control the arc burning time of the system. In the practice teaching of horizontal and vertical fixed welding of φ 57 × 3.5 pipes, the arc breaking method is used for welding. When the bottom layer is welded, the frequency of the arc breaking and the arc burning time directly affect the temperature of the molten pool. Because the pipe wall is thin, the ability to withstand the heat of the arc is limited. If the arc breaking frequency is slowed down to reduce the temperature of the molten pool, shrinkage cavities are likely to occur, Only the arc burning time can be used to control the temperature of the molten pool. If the temperature of the molten pool is too high and the molten hole is large, the arc burning time can be reduced to reduce the temperature of the molten pool. At this time, the molten hole becomes smaller, and the forming height inside the pipe is moderate, so as to avoid welding seams or weld beading inside the pipe.
3. Diameter
Welding current and electrode diameter: the welding current and electrode diameter are selected according to the spatial position of the weld and the welding level. When starting welding, the welding current and electrode diameter are larger, and the vertical and horizontal positions are smaller. For example, φ 3.2mm welding rod is selected for the bottom layer of 12mm flat butt welding, welding current: 80-85a, filling, and φ 4.0mm welding rod is selected for the cover layer, welding current: 165-175a, reasonable selection of welding current and electrode diameter, easy control of molten pool temperature, is the basis of weld formation.
4. Methods
The method of electrode moving: the temperature of the molten pool for circular electrode moving is higher than that for crescent electrode moving, and the temperature of crescent electrode moving is higher than that of the molten pool for zigzag electrode moving. When the bottom layer is sealed at 12mm, the zigzag electrode moving is used, and the swing amplitude and pause on both sides of the groove are used to effectively control the temperature of the molten pool, so that the size of the molten hole is basically the same
Robot welding stud workstation
The robot welding stud workstation uses robots to weld studs to workpieces for studs with different specifications on complex parts. The workstation is mainly composed of robot, stud welding power supply, automatic nail feeding machine, robot automatic stud welding, positioner, fixture, automatic change device, automatic detection software, control system and safety barrier. The stud is sent to the robot automatic welding through the automatic nail feeding machine, and the robot is programmed to show the path on the workpiece, Weld studs of different specifications to the workpiece. Energy storage welding or arc welding can be used to firmly weld the stud to the workpiece, --- welding precision and welding strength. The welding efficiency is about 3-10 pieces/minute, and the stud specification is 3-8mm in diameter and 5-40mm in length.
How about the flexibility and welding of welding robot?
As we all know, many companies in the welding industry use welding robots, because robots not only produce, but also have many advantages, which is why enterprises use welding robots to replace traditional manual work. The welding robot not only has the advantages of good stability, but also has the flexibility to work stably even in complex environments. This is closely related to the structure of welding robot, including welding robot body, welding power source, one-dimensional heavy sliding table, robot L-arm, welding cleaning and wire cutting station, control system and other equipment. How about the welding robot? If there is a yellow coating on the surface of the manual weld, the welding robot can weld to avoid similar problems, welding. First of all, we must know that the yellow things are actually impurities in the welding wire and welding matrix. It is mainly the high temperature oxidation of silicon and manganese during welding and the chemical reaction in shielding gas, as well as the oxidation reaction formed by silicon oxide and manganese oxide. It is somewhat similar to the welding slag in manual welding. Although these phenomena are also caused by the use of welding robots, these oxides will not adversely affect welding except for their slight appearance, and can be easily removed by brush. The metal elements of solder substrate contain some silicon and manganese, which must exist. If you want to reduce these oxides, you can use less silicon and manganese welding wire, use less shielding gas, and use mixed gas. Fewer oxide welds and fewer yellow spots.
