Abstract

Provided are a weld seam structure and a welding process suitable for a narrow-gap water-cooled wall tube panel. The weld seam structure comprises a groove-type gap formed between adjacent water-cooled wall tubes, where welding joints are arranged on sides of the adjacent water-cooled wall tubes that are close to each other, and the welding joints are distributed on an upper side of the groove-type gap, and the welding joints communicate with the groove-type gap. In addition to the original welding joints, the adjacent water-cooled wall tubes are considered as a whole; and the gap between the water-cooled wall tubes is processed into a groove type and welded together with the welding joints, which increases the thickness of the weld seam at the tangent point and the safety factor, also facilitates performing radiographic non-destructive testing.
