摘要： A build-up spraying apparatus is disclosed which is capable of positionally adjusting the spreading rate of build-up metal powder on an article along the spreading direction to satisfactorily carry out partial or local build-up as well as uniform build-up as desired. The build-up spraying apparatus includes a fluid control device for spreading build-up metal powder having a pair of control gas injection nozzles formed at the both sides of the interior thereof and a control gas switching cycle setting means for supplying two systems of control gas to the fluid control device at a predetermined cycle to positionally control the spreading rate of build-up metal powder in the spreading direction. The apparatus also includes at least one heating burner body for heating build-up metal powder ejected from the fluid control device, the heating burner body being adapted to vary the amount of heat according to the difference in injection rate of build-up metal powder in the spreading direction.

摘要： A method of field welding head-hardened rails which includes the steps of gas pressure welding the rails, shearing off excess metal therefrom at the welded portion with a portable welder device, subjecting the railhead of the pressure welded portion of the rails to a subsequent heat treatment with a gas heater device, setting a width of the pressure welded portion to be heated at the time of the subsequent heat treatment with a pair of jigs, and cooling the portion which has undergone the subsequent heat treatment with an air blowing type cooler.
摘要翻译：一种现场焊接头硬化轨道的方法，包括气压焊接轨道的步骤，在焊接部分用便携式焊接装置从其上剪切多余的金属，使轨道的压焊部分的轨头经受后续热用气体加热装置进行处理，用随后的热处理设定待加热的压焊部分的宽度，并用吹风式冷却器冷却经过随后的热处理的部分。
