I found out the reason and guessed that the welding temperature of the workers was too high, which should not exceed 220 degrees Celsius. I would like to ask, what will happen if the HDPE exceeds 220 degrees Celsius?

The welding speed is too fast, the base material does not melt and the welding wires do not melt each other.

The temperature is over 230. Reached 250. Does it also have an impact on the quality of butt welding?

PR hot melt butt welding does not require welding rods.

It will also have an impact. If the temperature is too high, changes in material properties will occur.
