Embodiment Construction

[0031] The present invention will be further described below in conjunction with embodiment:

[0032] A hollow ball welding process, comprising the following steps:

[0033] 1), basic processing flow:

[0034] Cutting→heating→press forming→cutting groove allowance→assembly of two hemispheres and ribs→welding;

[0035] 2) The welded hollow ball is made of Q235 steel plate (material GB700, specification GB709)

[0036] 3) Semi-automatic gas cutting (circle cutting with compass), profiling gas cutting and CNC flame gas cutting are used for welding ball billet blanking, and flame CNC cutting machine is recommended for high production efficiency;

[0037] 4) Before the billet is pressed, it should be heated in a reverberatory furnace or a resistance furnace, and the furnace should be uniformly heated to 10500C±500C and compared with a temperature card;

[0038] 5) For hemispherical compression molding, the mold size and heating temperature must be strictly controlled. The compre...

Abstract

The invention discloses a hollow ball welding technique. The hollow ball welding technique includes the following steps: material cutting, heating, compression-forming, groove allowance cutting, assembly of two half balls and ribbing plates, and welding; 2) hollow ball welding, a Q235 steel plate is adopted (material GB700, specification GB 709); 8) welding balls are arranged in a special rotatable rack when welding is performed through a hollow ball special fund automatic welder; the balls rotate at a uniform velocity on the rotatable rack, and a welding gun is fixed; welding adopts melting and gas shielded welding, and submerged-arc welding; CO2 gas shielded welding has the size and the requirement that: 2.1) material trademark: 16Mn(Q235); 2.2) position of welding: flat welding; 2.3) a welding requirement: welding by one side and dual-surface forming; 2.4) the groove size: V-shaped groove; 2.5) welding material H08Mn2siA Phi 1.2, solid core; 2.6) a welding machine, NBC-500; 9) assembly: 9.1) truncated edge 1mm-2mm; 9.2) clearing oil, rust, water in the groove and the range 10 mm away from two sides of the front surface of the groove to expose metal luster; 9.3) assembling clearance 4mm-5mm; and 9.4) tack weld.
