With the development of continuous welded rail (CWR) in China high speed railway, the innovative study has been carried out for the welding technique of track key part. Firstly, the paper introduces the traditional rail welding technique and its problems in China, and then, it proposes the new “SQ” gas welding technique on that basis, finally, it describes “SQ” gas welding technique in terms of technical feature, flow, economic benefit and application, which will be conductive to China railway track welding.
