Hybrid welding gas

Abstract

The invention discloses novel hybrid welding gas and belongs to the technical field of welding materials. The novel hybrid welding gas is prepared from the following components in percentage by weight: 20 percent of propylene, 20 percent of propane, 20 percent of liquefied petroleum gas and 40 percent of dimethyl ether; and 10 ml of methylbenzene, 10 ml of dimethyl ether, 20 ml of petroleum ether and 40 ml of acetone are added in a steel cylinder / 5 kilograms and are uniformly mixed. The hybrid welding gas has the benefits that the flame temperature can be more greatly improved, the cutting speed of the improved gas is improved by 30 percent compared with the cutting speed of the existing gas, the welding cost is reduced by 20 percent, the novel hybrid welding gas is suitable for various welding, and the cutting quality is remarkably superior to that before improvement.

Description

technical field [0001] The invention relates to a welding and cutting gas, in particular to a novel mixed welding and cutting gas, belonging to the technical field of welding materials. Background technique [0002] At present, industrial welding and cutting gas generally uses propane gas, which has a single component. The temperature generated by pure propane gas during cutting and combustion is low, which is not conducive to welding, and the cutting speed is relatively slow, which affects cutting efficiency. The amount of welding and cutting gas is large, and the cost of propane gas as welding and cutting gas is relatively high. At present, it is urgent to improve it to meet the actual industrial production needs. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a new type of welding and cutting gas that can greatly increase the flame temperature, has low cost, can be directly welded, and c...
