Abstract

A spirally oscillating wrap build-up welding method and equipment for long cylindrical body, such as the mould of long (14m) large-diameter (500 mm) nodular cast iron pipe, rotary drum type ball grinder, cylindrical container, etc features that the included spiral angle between wide welded band and cylinder's axis is 30-60 deg, welding gun is oscillating by 30-100 mm for ampletude and 30-50 times / min for frequency, and the adjacent welded bands are overlapped by 10 mm.

Description

technical field [0001] The invention relates to a kind of overall repair of nodular cast iron pipe molds with a length not exceeding 14M and an inner hole diameter greater than Φ500mm, and a wear-resistant and corrosion-resistant pre-protected surfacing welding for the inner and outer surfaces of a rotary drum type ball mill, a container body, and a cylinder. Treatment, can improve the thermal fatigue resistance of the inner wall surface of the long cylinder inner and outer wall winding spiral swing surfacing method and equipment. Background technique [0002] At present, in China, in terms of the overall surfacing welding of the inner wall of the steel long cylinder with an inner hole diameter greater than Φ500mm at high temperature, due to the limitation of the inner hole size of the long cylinder member, the depth of the welding head, the delivery and recovery of welding wire and flux, As well as many factors such as the heat resistance limit of cables, motors, and electr...
