Sunshine panel greenhouse | Three points to pay attention to when changing the film in the greenhous

The manufacturer of the elliptical tube in the greenhouse believes that rust may sometimes be seen on the welded tube product or equipment before or during the manufacturing process, which indicates that the appearance is severely contaminated. It is necessary to remove the rust before the equipment is put into use, and the thoroughly cleaned appearance should be inspected by iron test and water test.

　　 Welding spatter has a lot to do with welding technology. TIG (Inert Gas Maintenance Tungsten Welding) has no spatter. However, when using GMAW (gas-maintained metal arc welding) and FCAW (arc welding with flux core) two welding techniques, if the welding parameters are used improperly, a lot of spatter will be formed. When this situation appears, it is necessary to adjust the parameters.

　　 If you want to solve the problem of welding spatter, you should apply anti-splash agent on each side of the joint before welding, which can eliminate the adhesion of spatter. After welding, the splash-proof agent and various spatters can be easily sorted out without damaging the appearance or causing slight damage.
