Comparison of different welding processes of motor windings under environmental pressure
Different welding processes used in winding processing of different motor manufacturers and motor repair manufacturers, such as gas bottles (such as liquefied gas, propane gas, acetylene gas) and oxygen cylinders, this process belongs to hydrocarbon flame, this flame Have certain defects or limitations.
1. Gas and oxygen welding process
●The flame temperature is relatively low, which is easy to cause virtual welding and de-soldering, which affects product quality;
● The flame is relatively divergent, which is easy to cause the paint to be stripped adjacent to the enameled wire and cause poor insulation;
● Gas bottles and oxygen cylinders are pressure vessels and have certain safety risks;
● Gas leakage may cause poisoning or even death;
●Because the flame temperature is low, the relative welding efficiency is also correspondingly low;
● Gas cylinders need to be stored and transported, and they also require working hours. If the gas is not delivered in time, it will seriously affect production.
2. Hydrogen and oxygen flame welding process
Hydrogen-oxygen flame welding machine, also known as water welder, hydrogen-oxygen machine, hydrogen-oxygen welder, uses the principle of water electrolysis to convert water (H2O) into hydrogen and oxygen by electricity, and ignites it by a special flame gun to form an oxyhydrogen flame. Fast automatic paint stripping of the enameled wire. Hydrogen-oxygen flame welding has the advantages of smooth and full solder joints, fast welding speed, safety and environmental protection.
● The temperature of the hydrogen-oxygen flame is as high as 2800 degrees, which is one of the highest temperature flames at present;
● The calorific value of hydrogen is 34,000 kcal, which is about 3 times that of liquefied gas;
● The oxyhydrogen flame is concentrated, does not diverge, and the heat radiation is small;
●Hydrogen-oxygen combustion only produces water, no waste gas is generated, and it is environmentally friendly equipment;
● The raw material produced by hydrogen-oxygen gas is water, consumes a small amount of electricity, is manufactured on demand, how much is produced, no gas is stored, and there are no problems such as high-pressure explosion and leakage poisoning;
●Starting gas production, shutting down the gas, ready to use, no need to produce;
●The process of removing the paint peel is not required, and it is not necessary to directly paint the paint;
●The welding flame is fine and will not generate heat radiation to the adjacent enameled wire;
● The solder joints are smooth and full.
But objectively speaking, no matter what kind of process, it is related to the skill level of the operator. If the wire end to be welded is properly treated, the welding effect will be natural. Otherwise, the effect will not be affected at the same time.
