Robot welding, detailed explanation of speed, parameters, and process parameters

The specific value of robot welding speed depends on the welding task and the different welding materials. Generally speaking, the welding speed of robots can be between 20 and 60 centimeters per minute, depending on the welding speed, distance during welding, weld size, and the matching performance of the robot.

The technical parameters of robot welding include: number of robot axes, robot load capacity, working radius, repeated positioning accuracy, maximum speed, control system, etc. Among them, the number of robot axes and load capacity are parameters selected based on the needs of the workpiece and welding process, the working radius is the effective working space radius of the robot, the repeated positioning accuracy is the ability of the robot to maintain accuracy in multiple operations, the maximum speed is the maximum operating speed that the robot can reach, and the control system is the core of robot operation and monitoring.

The process parameters of robot welding include welding current, voltage, welding speed, welding distance, welding duration, protective gas flow rate, etc. Among them, the welding current and voltage should be selected based on the properties of the welding material and welding method, the welding speed and distance are related to the shape and size of the weld seam, the welding duration should be selected based on the requirements of welding quality, and the protective gas flow rate should ensure that the welding area can be adequately protected.

According to specific welding specifications and robot types, the robot welding speed is between 50-160cm/min. For example, the welding speed of a six axis welding robot can reach 50-160cm/min, while the welding speed of a four axis robot is relatively slow, generally between 40-90cm/min. In addition, the welding speed of robots is influenced by multiple factors, such as welding parameters such as welding current, voltage, gas flow rate, as well as the control system and performance of the robot. Therefore, in practical applications, adjustments and optimizations need to be made according to specific situations to achieve the best welding effect.
