Weld Pool Temperature Control with Yaskawa Welding Robots: Expert Tips

Yaskawa welding robots, during their welding operations, have their pool temperature dependent on numerous factors.

The correct operation of these robots by technical personnel encompasses elements such as wire angle, welding time, wire diameter, and welding process.

Therefore, if the pool temperature is found to be excessive, technicians need to cool it down, focusing on several aspects.

In the welding production process with Yaskawa robots, when the angle between the welding wire and the welding position is 90 degrees, the arc concentrates, leading to a high pool temperature.

Conversely, with a smaller angle, the arc disperses, resulting in a lower pool temperature.

For instance, while welding the bottom layer of a 12mm flat weld, the wire angle should be controlled within 60-70 degrees to reduce the pool temperature, preventing the formation of weld scars or pitting.

Furthermore, strict control of the system’s arc burn time is crucial, as the frequency of arc breaking and the arc burn time directly affect the pool temperature.

Since the wall thickness is thin and the heat tolerance of the arc is limited, slowing down the arc breaking frequency to reduce the pool temperature can lead to porosity.

Therefore, the burn time of the arc should be used to control the pool temperature, preventing excessively high weld seams or the formation of scars inside the pipe.

Under conventional circumstances, Yaskawa welding robot technicians are required to choose the welding current and wire diameter based on the welding seam’s spatial position and layers.

A larger welding current and wire diameter are used at the start of welding, and smaller ones for vertical and horizontal positions.

Only in this way can the pool temperature be easily controlled, enabling the formation of the weld seam.

Based on past experience, when Yaskawa welding robots use a circular motion path, the pool diameter temperature is higher than that of a crescent motion path, and the crescent motion path temperature is higher than that of a jagged motion path.

Thus, it is advisable to use a jagged motion path as much as possible, along with the sway amplitude and pauses on either side of the groove, effectively controlling the pool temperature.
