Hand cranked heat fusion butt welder is a commonly used plastic pipe welding equipment, widely used in HDPE, PP and other plastic pipe connection. Pressure control is a very critical part of the welding process, which directly affects the quality of the welded joint. Therefore, how to accurately measure and adjust the pressure during the welding process is an important guarantee to improve the welding quality.
Pressure is the size of the force per unit area, commonly used units of pressure are bar (bar), Pascal (Pa) and so on. Pressure gauge by measuring the deformation of elastic elements (such as springs, bellows, etc.) to determine the size of the pressure, the common pressure gauge mercury column pressure gauge, spring tube pressure gauge. The basic requirements of pressure measurement is accuracy, stability, range, etc..
Unlike the hydraulic heat fusion butt welder which uses a hydraulic station to set and observe the pressure, the hand cranked heat fusion butt welder has a pressure gauge mounted on the frame to measure the pressure.
The operator needs to calibrate the pressure gauge regularly to ensure its accuracy and reliability. During the welding process, the welding pressure is adjusted in real time by observing the data from the pressure gauge to achieve the desired welding effect.
Users should record the pressure measurement data, including time, temperature, pressure values, etc., analyse the data, assess the quality and efficiency of welding, identify potential problems in time, adjust welding parameters according to the results of data analysis, and optimise the welding process.
In conclusion, hand cranked heat fusion butt welder pressure measurement is a critical part of ensuring weld quality.
