粉末火焰焊涂是将高级合金焊涂在需满足磨损、腐蚀、温度等综合要求或在出现一定的密损状态后需予复原的工件上的新工艺。在美国和某些欧洲国家已制成了装有粉末容器的气体喷焊器。本文介绍 Castolin S.A.公司出品、名为 Kooltip 的 C 型焊炬。该公司的氧乙炔焊炬共有三种型号,C 型是最大的一种。它工作时的氧气压力是2.0公斤/厘米~2,乙炔压力是0.7公斤/厘米~2。固定在焊炬上的塑料容器内装有金属粉末。粉状合金流经喷咀,被火焰喷涂在工件上(见图)。用拇指操纵的棍杆能调节在焊炬内流过的金属粉
Powder flame welding is the advanced alloy welding to be worn in the need to meet the wear and tear, corrosion, temperature and other integrated requirements or in the event of a certain loss of state to be restored after the new work piece. In the United States and some European countries have been made with a powder container gas jet welding. This article describes the C-type welding torch manufactured by Castolin S.A. and titled Kooltip. The company’s oxyacetylene welding torch there are three models, C-type is the largest one. Its working oxygen pressure is 2.0 kg / cm ~ 2, acetylene pressure is 0.7 kg / cm ~ 2. The plastic container fixed to the welding torch contains metal powder. The powdered alloy flows through the nozzle and is flame sprayed onto the workpiece (see figure). A thumb-operated club adjusts the metal powder flowing through the torch
