焊机是指受过培训的人，并能够使用SMAW，GTAW和FCAW工艺在板和/或管上的所有位置焊接黑色和有色金属。焊工使用手动或半自动焊接设备。他们使用火焰切割，钎焊和起弧设备。此外，他们使用诸如刹车，剪板机和其他金属矫直和弯曲机之类的机器。焊工通常根据图纸或通过分析工作任务来计划工作，确定所需的材料和焊接工艺，然后利用他们的焊接知识来完成工作。他们可能擅长某些类型的焊接，例如定制制造，造船和维修，压力容器焊接，管道建筑焊接，结构建筑焊接或机械设备维修焊接。工人使用蓝图符号来确定加工操作。他们使用精密测量仪器检
A Welder is a person who has training in and is capable of welding ferrous and non-ferrous metals in all positions, on both plate and/or pipe, using SMAW, GTAW, and FCAW processes. Welders use manual or semi-automatic welding equipment. They use flame-cutting, brazing and air-arcing equipment. Additionally, they use machines such as brakes, shears and other metal straightening and bending machines. Welders generally plan work from drawings or by analyzing the job tasks, determine the materials required and welding processes, then use their knowledge of welding to complete the job. They may specialize in certain types of welding such as custom fabrication, ship building and repair, pressure vessel welding, pipeline construction welding, structural construction welding or machinery and equipment repair welding. Workers use blueprint symbols to determine machining operations. They check product specifications using precision measuring instruments, and maintain equipment and replace parts when required.
