Huaheng high-efficiency hot wire welding process - high efficiency, high cladding, high quality, "three high" pipeline hot wire TIG welding.
Offshore engineering, petrochemical and other industries have relatively high requirements for pipeline prefabrication, and the amount of engineering is relatively large. The traditional TIG welding manual bottoming and MIG welding filling cover surface are not ideal in quality and efficiency. Huaheng adopts a new welding process - high-efficiency hot wire TIG welding, to realize TIG bottom welding, filling welding and cover welding, and achieve the high-efficiency welding method of MIG welding to replace the traditional method. Through this kind of experiment, it is proved to be effective to study its mechanical properties, and it has been successfully used in the industry.

Huaheng high-efficiency hot wire welding process performance characteristics: |
1. TIG welding quality and MIG welding speed - more than 5 times more efficient than traditional TIG, comparable to MIG welding speed; 2. Higher cladding efficiency--from 0.3-0.5kg/h (traditional cold wire) to 2-4kg/h (H-TIG); 3. Better welding quality - due to the application of advanced technology methods such as pulsating wire feeding, pulsed hot wire, superimposed high frequency + sharp pulse, etc., the effects of molten pool stirring, grain refinement, and increased penetration are achieved. Improved quality and efficiency; 4. Arc length tracking - no intervention in the welding process; 5. High efficiency, carbon steel φ108*10mm, 8-10 minutes; 6. Weldable materials: carbon steel, alloy steel, stainless steel, nickel-based alloy, duplex stainless steel, etc.; especially suitable for duplex stainless steel welding; 7. Groove form: U-shaped groove, V-shaped groove and double V-shaped groove can be used. |
