Embodiment 1
[0029] In this embodiment, the Ni stainless steel plate 1 and the stainless steel plate 11 having a thickness of 9 mm and a width of 1500 mm are welded.
[0030] The butt welding method embodiment of the stainless steel plate is the following sequential steps:
[0031] 1. Cut off the uneven arc portion of the material head 5 of the stainless steel plate 1, and cut off the uneven arc portion of the material tail 9 of the stainless steel plate 11 to make the welding surface smooth, see figure 1 and figure 2 ;
[0032] 2. Place the material head 5 of the stainless steel plate 1 and the material tail 9 of the stainless steel plate 11 on the platform 3 of the welding machine 2, open the feeding roller to adjust the gap 8 between the material head 5 and the material tail 9 of the two stainless steel plates to 2.2 mm~2.4mm, the gap 8 is located directly below the welding torch, and the material head 5 and the material tail 9 are pressed tightly by the pressure plate 4 and the pres...
Embodiment 2
[0037] In this embodiment, a Ni stainless steel plate 1 and a stainless steel plate 11 with a thickness of 12 mm and a width of 1500 mm are welded.
[0038] The butt welding method embodiment of the stainless steel plate is the following sequential steps:
[0039] 1. Cut off the uneven arc portion of the material head 5 of the stainless steel plate 1, and cut off the uneven arc portion of the material tail 9 of the stainless steel plate 11 to make the welding surface smooth, see figure 1 and figure 2 ;
[0040] 2. Place the material head 5 of the stainless steel plate 1 and the material tail 9 of the stainless steel plate 11 on the platform 3 of the welding machine 2, open the feeding roller to adjust the gap 8 between the material head 5 and the material tail 9 of the two stainless steel plates to 2.8 mm ~ 3.0mm, and use the pressure plate 4 and the pressure plate 10 to compress the material head 5 and the material tail 9 respectively;
[0041] 3. Select the welding torch...
Embodiment 3
[0045] In this embodiment, two coils of Ni stainless steel with a thickness of 10 mm and a width of 1500 mm are welded.
[0046] The butt welding method embodiment of the stainless steel plate is the following sequential steps:
[0047] 1. Cut off the uneven arc part of the material head of one stainless steel coil, and cut off the uneven arc part of the material tail of the other stainless steel coil to make the welding surface smooth;
[0048] 2. Place the head of the stainless steel coil and the tail of another stainless steel coil on the platform 3 of the welding machine 2, open the feeding roller to adjust the gap between the head of the stainless steel coil and the tail of another stainless steel coil to 2.2mm~ 2.6mm, and use the pressure plate 4 and the pressure plate 10 to compress the material head and the material tail respectively, and the gap is located directly below the welding torch;
[0049] 3. Select the welding torch used during welding; adopt the first weld...
