Stainless steel steel solders the operation makes a request

The construction that contacts many large projects jackarooes. The work out includes the construction such as container of type of conduit, storage tank, tower, steel structure to plan program or the programme of construction too. Through these construction arrangement plans to apply mediumly in the project, make from accumulated a few experience, and to stainless steel this is planted of raw material solder had know further. Contact pipeline construction now. In the light of stainless steel the technical management in solder and quality are held accuse, when to talk to comprehend.
1 conclude solder technology
The brand of stainless steel is very much. By alloy composition can divide stainless steel of the department that it is chromium and chromic nickel stainless steel. By the metal of stainless steel arrangement can be divided for abstruse family name model, ferrite, Martens bodily form. And the most commonly used in construction is austenite model, be like: 0Crl9Ni9, 1Crl8Ni9Ti. The weldability of austenite stainless steel has contrasted, opposite contrast solders simply, solder contact even if also has taller patience in as welded. But with normally carbon steel photograph is compared, its heat conduction leads the 1/3 that is carbolic steel about, coefficient of expansion is bigger than carbolic steel however 1. 5 times. Because austenite stainless steel has inferior heat conduction rate and more expensive coefficient of expansion, so soldering the meeting in the process happens bigger be out of shape and meet an emergency. Solder so quality is chief depend on solder the technology suits with photograph of mother capable person. Be in for this conclude solder when the technology. Be necessary to undertake reflection from the following respect.
Solder of method choose stainless steel to solder commonly usedly method has craft arc welding, gas to safeguard solder to reach bury arc solder actively. Principal the medium parameter that is basis program, execution condition and operation environment, and construction capital conclude. In technical pipeline construction, because be in charge of diameter size to differ, and the valve on conduit, pipe fitting is more, make change of solder opening position more mixed and disorderly. All choose craft arc welding normally so. Explode combustibly, easily about carrying or medium has sure and clean the conduit that spends a request, choose render of argon arc solder normally. Craft arc welding builds the means of the face to solder, with the immanent quality of ascensive welding line. Solder of the data choose stainless steel welding rod to divide welding rod of the stainless steel that it is chromium (brand is " G " word head) with welding rod of chromic nickel stainless steel (brand is " A " word head) . Welding rod of chromic stainless steel is principal use at bodily form stainless steel to solder. Of welding rod choose principal electric current of temperature of medium of the chemical composition from mother capable person, conduit and pressure, welder (communicate or flow continuously) , solder the many sided such as temperature ponders over method and the environment when soldering. Normally for, admit through choosing, the welding rod that can have many brand is OK and satisfactory solder request. Can compare according to the sexual price of welding rod at this moment preferred choose.
