How to Surfacing the stabilizer by PTA welding

We have a rich experience in PTA welding， more than fifty corporations in oil and gas industry purchased from us, such as Baker Huges and  Schlumberger  etc.

We have the unique solution to PTA welding stabilizer for preheating as well. The high frenquency induction heating is for the larger stabilizer.

1 The three spiral surfaces of the stabilizer are programmed by numerical control, and the G code is adopted to realize the walking track on the spiral surface. The program is copied every 120° to realize the surfacing of the three spiral surfaces.

2 For the 15°slope of the centralizer, the surfacing method is as follows:

(1) If it is sleeve, the positioner can be changed 15°to make the slop to turn into horizontal, and then surfacing.

(2) If it is shaft, the trajectory of torch can be changed by adding Z-axis to realize slope surfacing
