通过焊接参数的选定(焊接电流 I =150A,电压 U = 8.8V,焊接速度 0.7~1m/min),保证单根导体长度不小于 300m,焊缝无气孔,裂纹等焊接缺陷。使焊接后的 CICC 超导导体内部最接近焊缝位置的温度低于 183℃,确保导体导电性能,导体焊缝耐压试验不低于 5MPa,且氦气密性能良好,研制出的产品满足相关技术标准的质量要求。
Abstract
Better weld quality is received by choosing technical parameter of weld (weld current is 150A
weld voltage is 8.8V
weld speed is 0.7~1.0 m/min). There is no pore and flaw in weld seam of the product
the temperature of proximal weld seam in welded CICC conduct is less than 183℃, so the electric is better. Compression resistance of weld seam is more than 5 MPa
and airproof capability is better. Product can meet demands of specifi cation.
