316 stainless steel pipe is commonly used in petroleum, chemical, food and other industrial transportation pipeline, which has high requirements for the weld quality of the pipe, such as allowing leakage welding phenomenon. And when welding, if the staff is not skilled in welding technology, or if the welding is not checked in time after welding, there may be leakage welding.
Welding errors are generally due to these reasons, may be too high current melted or current is too small to weld, just adjust the appropriate current; may be the torch left or right is not aligned or the torch position is too high, adjust the machine master will be the torch aligned on the good; may be no argon, weld fire is not centralized, replace the argon on it; may be the molds and steel bands with water or oil, resulting in weld fire is not concentrated, with the use of water, turpentine or toluene to clean the steel bands will be no problem. The water, turpentine or toluene to clean the steel belt will be no problem. Of course, there are other factors causing 316 stainless steel pipe leakage welding.
Infrared leakage welding detection equipment is usually used to detect whether there is a leakage of welding. Infrared leakage weld detection is a non-destructive test, which uses the method of measuring the infrared radiation of the component to obtain the surface temperature or temperature distribution to determine whether there are internal defects in the operating state technology. If a weld leakage is found, the equipment will issue an alarm message, and the production machine will automatically cut off the 316 stainless steel pipe corresponding to the alarm, in order to prevent the missed pipe from flowing into the next process.
