Description

technical field [0001] The invention belongs to the field of anti-corrosion steel pipe production equipment, in particular to a full-automatic argon arc welding machine for anti-corrosion steel pipe lined with stainless steel end sleeves. Background technique [0002] When the plastic-coated anti-corrosion steel pipe is butt-welded, it will inevitably cause damage to the inner coating at the end. Larger diameter pipes can be artificially repaired, while smaller diameter pipes cannot be artificially repaired. A leak in the anti-corrosion layer is formed. In order to prevent this from happening, in the production of small anti-corrosion steel pipes, argon arc welding machine is usually used to weld a stainless steel end sleeve on the inner layer of the end of the steel pipe to prevent the anti-corrosion steel pipe from forming an anti-corrosion layer leak at the end during welding. . In the past, when welding stainless steel end sleeves, manual welding was mostly used, and m...

AI Technical Summary

Problems solved by technology

Hand-held welding torches are used for manual welding. Keeping a posture for a long time and staring at the welding spots closely will cause fatigue to both the body and the eyes, and the labor intensity of the operators is high. Second, the speed is slow and the efficiency is low.

During welding, the steel pipe rotates on the welding table. Due to the roundness error of the steel pipe itself and the concentricity error of the welding table rollers, the steel pipe will produce slight changes at any time in both the axial and radial directions, resulting in irregular changes in the solder joints. In addition, during manual welding, the operator is in a dynamic state, and it is difficult to manually control the solder joints. We must be constantly looking for and adjusting the solder joints during welding, which will inevitably affect the welding speed.

Third, poor welding quality

Due to the roundness error of the steel pipe itself and the concentricity error of the welding table rollers, the irregular changes in the solder joints and the instability of the personnel themselves will slow down the welding speed and cause wide and uneven welds. The waste of welding materials affects the welding quality to a certain extent, making the welding quality poor
