TECHNOLOGICAL PROCESS OF WIDE BAND ELECTRIC SURFACING WITH AN INTRODUCTION TO THE WELD POOL FILLER MATERIAL AND ULTRASONIC VIBRATIONS
Recommended application field:
Repair and refurbishment production machines.
Advantages over analogues:
The technology allows to obtain high quality weld surface with a homogeneous structure without any major defects. The developed technology and equipment shirokopolosovoy arc welding consumables saves 20-30%, by reducing the pass machining and surface build-up losses of welding materials; reducing electricity consumption by 15-20% due to increase deposition rate; improved performance surfacing parts 2-2.5 times; reduce the cost of details by 20-30%.
Description of the development: () The technological process allows to obtain a single pass weld bead quality with a homogeneous structure.
- Width 30 mm;
- Height of up to 5 mm;
- Welding voltage - 24-30 V;
- Welding current - 200-400 A;
- The amplitude of oscillation of the electrode - 5.10 mm;
- The frequency of oscillation of the electrode - 0.4-0.6 Hz;
- Deposition rate - 2.5-5 mm / s;
- The frequency of ultrasonic testing - 22-24 kHz;
- Oscillation amplitude - 9-10 microns;
- Consumption of MRP (PG-SRH) - 0.2-0.8 g / s).
Introduction to the weld pool MRP (PG-SRH) in an amount of 10 to 30% by weight of the welding wire produces weld beads with a hardness of 20-40 HRC, iznosotoykost increases by 1.5-2 times. Introduction to the weld pool UT further improves wear resistance by 10-30%. Process technology and equipment is not inferior to the world analogues (Castolin, Switzerland). The technology is environmentally friendly, emission of harmful substances belong to the category welding and provides local ventilation to the content of harmful substances below the MRL.
