The main factors that determine the welding quality by hot melt butt joint parameters are as follows:
1. The temperature when the heat is absorbed
PE80 national standard 210 degrees / plus or minus 10 degrees. British standard 233 degrees / plus or minus 3 degrees; PE100 national standard 225 degrees / plus or minus 10 degrees. Detect the temperature of the welding circle on the surface of the hot plate. The smaller the temperature error, the more stable the welding quality.
2. Welding time:
SDR11 national standard pipe diameter ÷ 11 × 10 = welding time, SDR 17.6 national standard pipe diameter ÷ 17.6 × 10 = welding time.
3. Cooling time
Pressure: The national standard is drag pressure to absorb heat, the British standard is pressure to absorb heat, drag pressure + welding pressure = butt pressure. Drag pressure: it is the pressure at which the pipe can be dragged when the machine is running. Welding pressure: the pressure given by the national standard ÷ the cross-sectional area of ​​the welding machine cylinder = the welding pressure.
4. Welding pressure,
Welding pressure + dragging pressure: Welding pressure can be calculated by a formula, and the dragging pressure needs to be tested every time.
5. Clean the pipe welding surface
The cleanliness of the welding surface is very important. If the welding surface is accidentally stuck with oil, it will directly lead to a false welding. The specific surface is that the butt flanges that are planed out will separate.
6. Remove the flanging after welding.
More and more people have discovered false welds in advance by removing weld flanging, avoiding the risk of leakage after landfill. . .
