Embodiment
More detailed explanation is done to the present invention below by specific embodiment.
For the REPAIR WELDING of the anode steel claw head of the single four paws head of certain domestic electrolytic aluminium factory, the material of steel pawl head is
ZG230-450, intended diameter φ 180mm, design length 280mm, scaling loss segment length 140mm.
The first step, welding preparation
1）The scaling loss section of anode steel claw first 1 to be repaired and termination are cut off completely using gas cutting, remaining 110mm chooses
One section with round steel bar 2 of the anode steel claw head same material with diameter（Length is 136mm）, and to anode steel claw first 1 and round steel bar 2
Surface to be welded be machined out, make its surface roughness Ra=6.3 ~ 12.5 μm；
2）Play the processing of weld groove and end tab
According to the diameter of anode steel claw first 1, the cuboid steel plate that four block sizes are 150 × 180 × 50mm is chosen, and in length
One side of cube steel plate processes diameter 180mm semi-circular groove, by two block length cube steel plates and another block size be 180 ×
83 × 50mm cuboid steel plate（It is used as bottom plate）Weld groove has been welded into, weld groove structure has been played as shown in figure 1, the steel plate difference of both sides
For left supported plate 3, right supported plate 4, it is bottom plate 5 to pad in left supported plate 3 and the bottom of right supported plate 4, and another two blocks of steel plates are standby；
Assembled before second step, weldering
As shown in Fig. 2 anode steel claw first 1 and round steel bar 2 that the first step is treated have lain in a horizontal plane in weld groove respectively
In left supported plate 3 and the semi-circular groove of right supported plate 4, it is ensured that the two axle center is consistent, the fit-up gap of adjustment therebetween has been in weld groove
Middle part, standby two blocks of steel plates correspondence is withheld in anode steel claw first 1 and the top of round steel bar 2, left end tab 6 is formed and the right side is drawn
Ejecting plate 7；Then left end tab 6, right end tab 7 and left supported plate 3, right supported plate 4 are respectively perpendicular correspondence and are welded on anode steel claw
First 1 and the upper and lower part of round steel bar 2；
During actual processing, the surface to be welded of anode steel claw first 1 and round steel bar 2 can be processed to the angled different frustum of a cone
Shape, makes to be formed therebetween the fit-up gap with upper and lower groove as shown in Figure 3 or Figure 4.The fit-up gap of the present invention, such as
Shown in Fig. 3, groove fit-up gap is 33mm thereon, and lower groove fit-up gap is 35mm.
Fixed respectively on two other side for not installing the end tab of anode steel claw first 1 and round steel bar 2 and a weld groove
There is water cooling sliding block 8（Water cooling sliding block 8 can use the Copper Water Jacket with entery and delivery port）, it is therefore an objective in welding, using being passed through water cooling
Circulating water in the inner chamber of sliding block 8 takes away the heat in weld seam, is so both beneficial to the shaping of weld seam, again the tissue of weld seam can be made thin
Change；Then the consumable nozzle clamping device 9 of welding machine is fixed：Consumable nozzle 10 is fixed on to the front end of clamping device 9, and adjusts consumable nozzle folder
Mechanism is held, consumable nozzle 10 is in the centre of fit-up gap（Namely play the center of weld groove）；
3rd step, welding
According to the material and joint form of steel pawl head and round steel bar, the wire feed rate of welding machine is set to 180~200m/h,
Weldingvoltage is set to 40~46V, and speed of welding control is in 0.6~0.8m/h, and for the benefit of deslagging in welding process, keeps continuing
Implement welding, depth of slag bath is set to 45~55mm, is then electrified to welding；
4th step, after welding treatment
Welding is finished, and by left end tab 6, right end tab 7 and a weld groove excision, polishing welding seams metal 11 makes itself and steel pawl
First 1 and round steel bar 2 seamlessly transit, complete the reparation of the anode steel claw head.
