2. open the welding equipment power supply, and connect inert protective gas;
3. the welding gun with electric welding machine moves to the welding position, electric arc ignites, thread babbit is delivered to fusing back, electric arc place spot distribution in the surface of part, the surperficial mother metal of part does not melt, synchronous horizontal moves welding gun and thread babbit and makes the babbit of fusing be strip to be uniformly distributed in piece surface, after being close to article one babbit band vertical misalignment welding gun and thread babbit, laterally move once more to widen the babbit band, repeatedly repeat aforesaid operations and be covered in piece surface to forming a uniform babbit face, and can be on formed babbit face repetitive operation increase the thickness of piece surface babbit;
4. close the welding equipment power supply, stop to the logical inert protective gas in welding position, naturally the babbit layer of cooling institute soldering.
Welding process flow at piece surface babbit tungsten electrode noble gas protecting arc brazing is finished on automatic soldering device; described automatic soldering device comprises electric welding machine; the argon gas feed system; wire-feed motor; electric arc teeter device; the electric arc longitudinal moving device; positioner; part is fixed on the positioner; the tungsten electrode of electric welding machine extends initial welding position; wire-feed motor is delivered to thread babbit between the tungsten electrode and welding position of described electric welding machine welding gun; starting electric welding machine makes between tungsten electrode and the part and produces electric arc; lead to argon gas with the protection weld seam by the gas passage in the welding gun to the welding position simultaneously; the teeter device drives the welding gun transverse movement; and thread babbit and welding gun are synchronized with the movement, lengthwise movement is then driven by the electric arc longitudinal moving device and finishes.
Technique effect of the present invention:
1. mother metal does not melt in the welding process, has only packing material fusing, and the babbit surface deposited metal is on the surface of part, and the joint interface of babbit layer and part base solid was smooth after welding was finished.
2. improved the efficient of producing, the surface of part do not need to carry out pickling, ward off tin etc. anticipates, and has reduced and has anticipated link, thereby improved production efficiency.
3. the surface of part does not need pickling, wards off processing procedures such as tin, and the handling problem that has solved pickle has significance to environmental protection.
4. improved babbit and high base strength, the heat by welding arc forms babbit fusing back has certain thickness transition binder course, and bond strength obviously improves.
