Protection Gas Introduction Of 2.0MM-5.0MM Submerged ARC Welding Wire

Oct 12, 2017


2.0MM-5.0MM Submerged ARC Welding Wire is very much in the 2.0MM-5.0MM Submerged ARC Welding Wire on the different categories, users need to understand more 2.0MM-5.0MM Submerged ARC Welding Wire knowledge, contribute to the late Correct use, 2.0MM-5.0MM Submerged ARC Welding Wire manufacturers to introduce you to:
2.0MM-5.0MM Submerged ARC Welding Wire Protective gas Generally use Ar, He gas, flow to 25L / MIN for the appropriate steel electrode with high chromium content, solder gold with high tension, high toughness. Flux is a water-soluble flux, the appearance of colorless to pale yellow liquid. Sintered flux arc stability, easy slag removal, pure metal deposited, weld appearance, with good moisture resistance. Cast iron electrode can be AC and DC, more suitable for DC power supply reverse. Manual welding rod for general carbon steel structure and low strength grade low alloy steel, such as 09Mn2 and so on. Special electrode welding process is good, the workpiece is not preheated before welding, after welding without slow cooling, flux welding water after the residual flux clean or wipe with a damp cloth, which greatly saves the cleaning of organic solvents.
Gas protection 2.0MM-5.0MM Submerged ARC Welding Wire is mainly used in low carbon steel alloy steel, widely used in vehicles, bridge engineering, engineering machinery, steel structure, shipbuilding, container and other industries. After welding the electrode excellent mobility, excellent wetting, solder bright, oxidized residue residue rarely occur. Core Cores 2.0MM-5.0MM Submerged ARC Welding Wire is a multi-alloy reinforced high carbon high chromium cast iron surfacing material. Cast iron electrode can be directly surfing a variety of cast iron, pig iron mold. Professional production of the series of electrode production lines.
2.0MM-5.0MM Submerged ARC Welding Wire is the use of the same principle, for low-carbon steel and low alloy steel, generally choose 2.0MM-5.0 MM Submerged ARC Welding Wire is based on the principle of strength matching, that is 50 kg of steel on the selection of 50 kg class 2.0MM-5.0MM Submerged ARC Welding Wire, for example, Q345 steel, then use E501T-1 can. Different strength of the base metal between the welding, the general selection of lower grade base metal strength matching 2.0MM-5.0MM Submerged ARC Welding Wire.
There is also a stainless steel core 2.0MM-5.0MM Submerged ARC Welding Wire, which is austenitic stainless steel, this stainless steel 2.0MM-5.0MM Submerged ARC Welding Wire range of applications is not very wide, generally used for large pipes or thick plates Fill and cover, stainless steel 2.0MM-5.0MM Submerged ARC Welding Wire is used in the selection of chemical composition matches. 304 base metal selection 304 stainless steel 2.0MM-5.0MM Submerged ARC Welding Wire, 308 of the base metal selection of 308 stainless steel 2.0MM-5.0MM Submerged ARC Welding Wire.
If the carbon steel and stainless steel to welding, in general, can be used with 309L, if the requirements of special strict, then it requires the election in the bottom of the time, the need to consider the transition, that is, carbon steel side of the 2.0MM-5.0MM Submerged ARC Welding Wire composition of the dilution, filling and cover the same with the base metal stainless steel 2.0MM-5.0MM Submerged ARC Welding Wire can be.
2.0MM-5.0MM Submerged ARC Welding Wire in a variety of welding technology has a large area of use, 2.0MM-5.0MM Submerged ARC Welding Wire focus on all aspects of research and development, in the 2.0MM-5.0MM Submerged ARC Welding Wire Stored on the summary of a lot of skills, mainly including these points:
A storage of heat-resistant 2.0MM-5.0MM Submerged ARC Welding Wire warehouse should have a monotonous ventilation environment to prevent moisture; refused to water, acid, alkali and other liquids are very simple and volatile corrosive substances exist, but not with the coexistence of these substances warehouse.
Second, 2.0MM-5.0MM Submerged ARC Welding Wire should be placed on wooden pallets, can not be directly on the floor or close to the wall.
Third, access and handling 2.0MM-5.0MM Submerged ARC Welding Wire Note that do not break the packaging, especially the packaging "heat shrink film."
4, open 2.0MM-5.0MM Submerged ARC Welding Wire packaging should be used as soon as possible (need within a week), once 2.0MM-5.0MM Submerged ARC Welding Wire directly exposed to the air, the rust time will be greatly Shortened (especially in moist, corrosive media).
5, in accordance with the "first in first out" principle issued 2.0MM-5.0MM Submerged ARC Welding Wire, to minimize product inventory time.
6, please press 2.0MM-5.0MM Submerged ARC Welding Wire varieties, regulate the classification of storage, to prevent misuse.
