在石化装置工程建设和装置经长期运行后的检修工作中,需要大量的钢材切割、焊接、修补等施工内容。钢管、型钢连接焊接消耗大量的电焊机台班和电焊人工,焊接过程需用电焊机、电源、大口径电缆、电焊条等材料。现安装公司采用上海电焊机厂直流AX系列、ZX7系列焊机和交流BX1系列、BX6焊机,其中的大直流焊机性能稳定并且使用寿命较长,完全适宜检修施工长期环境使用的特点。供应电流的电缆可根据负载电焊机台数、功率,选择粗的电缆,以充分保证焊机正常工作。但是,配套使用的电焊钳在施焊过程由于多个原因,导致损坏率逐年上升的趋势。
In the petrochemical plant construction and installation after long-term maintenance work, the need for a large number of steel cutting, welding, repair and other construction content. Steel pipe, steel connection welding consume a large number of welding machines and welding welding station, welding process required welding machine, power supply, large diameter cables, welding rods and other materials. Installation company is now using the Shanghai Welding Factory DC AX series, ZX7 series welder and the exchange BX1 series, BX6 welder, one of the large DC welding machine with stable performance and long service life, fully suitable for long-term construction environment overhaul characteristics. Supply current cable welding machine according to the number of load, power, choose the rough cable, to fully guarantee the normal work of the welder. However, the use of supporting the use of welding clamp in the welding process due to several reasons, leading to a trend of increasing the rate of damage.
