柴油驱动双把焊接半自动炼化项目管道焊接石油化工行业对焊接设备的要求极为严苛：防爆、稳定、适应高盐雾腐蚀环境，且常常面临施工现场无稳定电源的困境。发电电焊机作为移动焊接解决方案，在石化装置建设、管道安装、设备检修等场景中发挥着不可替代的作用。
The petrochemical industry demands welding equipment with explosion-proof capabilities, high stability, and adaptability to high-salt corrosive environments — often with unstable or absent power supply at construction sites. Engine-driven power welders serve as mobile welding solutions, playing an irreplaceable role in petrochemical facility construction, pipeline installation, and equipment maintenance.
Case 1: Large-Scale Refining & Chemical Integration Project
采用50台HW800DS柴油发电电焊机，配备防盐雾处理。设备自带发电功能，摆脱对外部电源依赖；轮式底盘设计，单人即可推动转场，双把设计大幅提升焊接效率。
Deployed 50 units of HW800DS diesel engine welders with salt spray protection. Self-powered design eliminates external power dependency. Wheeled chassis allows single-operator mobility; dual-torch capability significantly boosts welding efficiency.

Case 2: Oil & Gas Pipeline Emergency Repair
某输油管线发生泄漏，需在最短时间内完成带压补焊。作业地点位于野外，无电力供应。抢修窗口极为有限，每延误1小时均造成重大经济损失。
A crude oil pipeline leak required immediate pressure welding repair at a remote location without power supply. Every hour of delay caused significant economic losses.
应用设备 / Equipment Used: WP-60S 电王四用一体机 × 2台
调用2台静音型WP-60S四用一体机，夜间噪音控制在65分贝以下，配备快速接头，30分钟内完成设备就位。该设备一机多能，现场即可完成发电、焊接、等离子切割修口等全部工序，无需额外调配空压设备。
Deployed 2 units of silent-type WP-60S 4-in-1 engine welders with noise below 65dB at night. Quick-connect fittings enabled 30-minute deployment. The all-in-one unit completed power generation, welding, and plasma cutting on-site without additional air compressor equipment.
