According to the thickness and diameter of the pipe wall, one or several welding distances can be used to move back and forth along the pipe to evenly heat.The heating width is within the range of 3 wall thickness on both sides of the groove, generally within the range of 50 ~ 100mm, and the minimum is no less than 50mm. The heating temperature can be measured with a temperature measuring Pen {{{}}

After welding, in order to reduce the cooling speed and prevent quenching and cracking, asbestos cloth should be used for insulation.
