Hello everyone.
Pinholes may occur at the end of welding.
The reason is... Sometimes it is due to the rapid cooling of the molten pool that penetrates the steel plate.
And this phenomenon often occurs when welding thin sheets.
Today, we will introduce several methods to reduce the cooling rate of the molten pool in TIG welding of thin sheets.
And “down slope time” and “crater current” also affect pinhole prevention.
In the future, we will introduce various details about pinholes.
Thank you for watching and have a great week.
