When using this process, the following key points should be paid attention to: during the welding process, the correct included angle between the welding handle, welding wire and weldment should be maintained. The ideal caster angle of the welding handle nozzle is & deg; & mdash; & deg;, change the included angle between the welding handle and weldment, change the welding speed, etc. to change the molten pool temperature, so as to ensure Beautiful weld formation (uniform width, no concave, convex and other defects) During operation, the current shall be slightly larger than that of solid core welding wire, and the welding handle shall be slightly adjusted to accelerate the separation of molten iron and molten flux coating, so as to facilitate the observation of molten pool and penetration; when filling the welding wire, it shall be sent to places of molten pool and pressed inward slightly to ensure penetration and prevent concave; during welding, the welding wire shall be regularly sent and taken out, and the welding wire shall always be ensured Under the protection of argon to prevent the end of the welding wire from being oxidized and affect the welding quality; pay attention to the welding quality of the arc and arc stop, and the spot weld shall be polished to & deg; the slope shall be gentle,GramshStainless steel water pipe clamp connection, and pay attention to the defects such as arc pit and shrinkage hole during arc stop.Austenitic stainless steel is generally used for manufacturing and manufacturing chemical equipment components, low-temperature equipment components in refrigeration industry, and can be used as stainless steel spring and clock spring after deformation strengthening.Gramsh,The existence of medium temperature brittle zone requires strict heat treatment and welding process system to avoid the appearance of harmful phase and damage the performance.Stainless steel pipes can be divided into CR series ( Series), Cr Ni series ( Series), Cr Mn Ni series ( Series) and precipitation hardening series ( Series). Series & mdash; Cr Ni Mn austenitic stainless steel series & mdash; Cr Ni austenitic stainless steel.Awasa,Austenitic stainless steel can be used to manufacture stainless spring, clock spring and steel wire rope in aviation structure after deformation strengthening. If welding is required after deformation,Gramsh304 stainless steel pipe price, spot welding process and deformation can only be used to increase the tendency of stress corrosionProduction mode stainless steel pipe can be divided into seamless pipe and welded pipe according to the production mode. Seamless steel pipe can be divided into hot-rolled pipe, cold-rolled pipe cold drawn pipe and pipe. Cold drawing and cold rolling are the secondary processing of steel pipe; Welded pipe is divided into straight seam welded pipe and spiral welded pipe.High frequency welding high frequency welding: with relatively high power supply, it can reach a higher welding speed for steel pipes with different materials, it is more than ten times its high welding speed. Therefore, stainless steel pipes for common use have a higher consumption rate. Due to the high speed of high frequency welding, high frequency welding Welded stainless steel pipe can not be borne by chemical and nuclear industries, which is also one of the reasons.

The product quality advantages of continuous casting billet of stainless steel pipe fittings are mainly reflected in that the non grinding rate of the outer surface of the billet except the head and tail section has reached more than %, and the total surface grinding yield has reached %. In order to achieve this goal, it is necessary to refine the molten steel, achieve low oxygen and sulfur content, do a good job in the metallurgy of the ladle and tundish, accurately determine the molten steel temperature, and realize no oxidation casting, Further reduce the inclusion content.: stainless steel rod: round rod, hexagonal rod, square steel, hexagonal angle steel, round steel, solid rod. Hexagonal rod and square steel (flat steel) are more expensive than round rod (most of the hexagonal rod specifications are imported high-quality materials). The bright surface is more expensive than black leather surface. Large diameter bars are mostly black leather rods. is a unique material in bars,Gramsh310 stainless steel pipe, which belongs to easy turning (cutting) materials, It is mainly used for self cutting. In addition f.cu.f also belong to easy cutting materials Series & mdash; Heat resistant chromium alloy steel.quality,There shall be a special storage rack. The storage rack shall be a wooden or painted carbon steel support or padded with rubber pad to isolate it from carbon steel and other metal materials. During storage, the storage position shall be convenient for lifting and absolutely isolated from other data storage areas. Protective measures shall be taken to avoid purification, collision with other components, purification and damage of iron metal.Indicates that the chemical composition is represented by international chemical element symbols and national symbols, and the composition content is represented by letters: for example, China and Russia use fixed digit numbers to represent steel series or numbers; For example, the United States, Japan, series, series and series; The serial number is composed of Latin letters and order, which only indicates the purpose.Therefore, there are requirements for the service environment of stainless steel, and it is necessary to remove dust frequently and keep it clean and dry.

It has the characteristics of high efficiency and low cost. At the same time, it can also well ensure the welding quality (in the capacity expansion and reconstruction project of Urumqi petrochemical we use this method to weld joints and repair joints, with a one-time qualified rate of welding), which is worthy of our use.Which one is better,Deburring: after the pipe is cut off, the burr shall be removed to avoid cutting the sealing ring.Choose the price.Flux coated welding wire (self shielded welding wire) shall be used for backing TIG welding.Gramsh,Stainless steel has two classifications: one is divided into chromium stainless steel and chromium nickel stainless steel according to the characteristics of alloy elements; The other is divided into m stainless steel, f stainless steel, a stainless steel and A-F duplex stainless steel according to the microstructure of steel in normalized state.During welding, the process of ventilation in advance and gas stop behind shall be adopted, and the adhesive cloth on the outside shall be torn off while welding. Because the blocking plate is composed of rubber and white iron sheet, it is not easy to be damaged, so this welding can well ensure that the inner side of the weld is filled with argon and its purity, so as to effectively ensure that the metal on the inner side of the weld is not oxidized and ensure the quality of weld backing welding.The surface resistance is less than mb; Wear protection; Scalable; Excellent chemical resistance; Good alkali metal and acid resistance; Strong toughness; Flame retardant.
