T-shaped plate one-side welding pulse bottoming welding method

Disclosed is a T-shaped plate one-side welding pulse bottoming welding method. An outer control device is added based on a common OTC welding machine, thus ultralow frequency pulse parameter welding is achieved, meanwhile, the pulse welding parameter is matched with an all-position welding trolley, and efficient automatic welding is achieved. Through pulse modulation, the pulse welding parameter is matched with the all-position welding trolley. The T-shaped plate one-side welding pulse bottoming welding method has very high practicability, the forming quality of the back side of an obtained welding joint is good, operation is simple, and welding quality is stable. The welding production efficiency is improved greatly, and very high popularization performance is achieved for achieving engineering application. 种T型板单面焊脉冲打底焊接方法，通过在普通OTC焊机的基础上添加外部控制装置，实现超低频脉冲参数焊接，同时与全位置焊接小车配合，实现高效的自动化焊接。通过脉冲调制实现脉冲焊接参数与全位置焊接小车相配合，本发明具有很强的实用性，获得的焊接接头背面成形质量好，并且操作简单，焊接质量稳定。焊接生产效率有了很大的提高，对于实现工程化应用具有很强的推广性。
