What should we pay attention to the Welding Positioner

As we all know that  Welding Positioner refers to the welding for assembling and fixing the position of the weld joint.

1.Be strict with the implementation of the welding process

Welding Positioner is often not welder attention, the welding process should be strictly controlled welding consumables S, P and other impurity elements. Formal welds need to be preheated, low temperature work environment and welding of large thickness of components, positioning welding should also be preheated in accordance with the temperature range.

2.Adjust the cooling rate

You can reduce the cooling rate by changing the heat input, positioning the welding arc to increase the swing frequency, increase the residence time and reduce the crater concavity.
