Product Description:

Specifications

The submerged arc welding wire series products feature excellent welding and mechanical performances. 

Submerged Arc Welding Wire

The products easily removable residue, good seam forming and highly efficient deposiyion.Wire meltingdoes not lead to splash or strong flasing.The sem surface is smooth and welding quality is guaranteed. They facilitate mechanical and automatic welding process. With a wide range of welding parameters, the wires can be used in open fields with strong wind and applied to automobiles, ships, bridges and chemical engineering.

 

Main Applications:

Applicable to welding of low-carbon steel and some low-alloy steel(such as 16Mn); automatic

submerged arc welding of boilers, pressure vessels, etc.

Q:Stainless steel wire braided hose, why so much water leakage ah?
That is, with the use of water leakage, not two from the middle tick, what can replace the water, the total change is not a thing ah?
Q:Stainless steel 304 work teeth, easy to break the silk work?
304 stainless steel is a common stainless steel material, the density of 7.93 g/cm3, the industry is also called 18/8 stainless steel. High temperature resistance of 800 degrees, with good processability, high toughness characteristics, widely used in industry and furniture decoration industry and food and medical industry.
Q:Stainless steel seamless pipe should pay attention to what?
First, the machine tool, electrical equipment grounding must be good, the collision block of two screws must be completeTwo, the repair or inspection of wire machine, you must cut off the machine power supplyThree. The safety guards, such as the grinding wheel protection cover and the belt shield, which are installed by the machine tool, must be intact and shall not be removed at random. All the fixing screws of the protective cover shall be tightened onlyFour, when you start the grinding wheel, no one shall stand in front of the grinding wheel to avoid accidentsFive, before starting the wire machine, the grinding wheel or drawing knife should leave the grinding roller for some distance, each appliance should be in the stop position, the grinding roller, the shaft sleeve, the grinding roll, the bearing and the stroke block must be adjusted properly and tightened
Q:Which kind of stainless steel welding wire is good? Is there any special regulation?
Welding wire for stainless steelThe composition of welding wire to be consistent with the welding of stainless steel welding into chromium stainless steel, using HoCr14 H1Cr13 H1Cr17 welding wire; chromium nickel stainless steel, using H0Cr19Ni9 HoCr19Ni9 HoCr19Ni9Ti wire;
Q:What mould do you use for cold drawn stainless steel wire?. How to deal with before cold drawing?
Overview of two processes:Hot-rolled (extrusion seamless pipe): billet, heating, perforation, three roll cross rolling, rolling or extrusion, tube to tube diameter (or reducing) - cooling - tube, straightening, pressure test (or testing), marking and warehousing.Cold drawing (rolling) seamless steel pipe: round tube to heating to perforation, annealing, pickling, leading to oil (copper), multi pass drawing (Leng Zha), the blank pipe, heat treatment, straightening, pressure test (testing), marking and warehousing.
Q:Stainless steel wire directly outside (one end of the end of the wire), what is appropriate?
If your problem is the process piping installation, the stainless steel outer thread can be used on the process line, and the casing can be installed and welded with argon filling protection.
Q:How can the stainless steel screws distinguish true from false?
You can use a magnet to see whether the screws will be adsorbed, can be adsorbed, it is not true stainless steel screws;
Q:How many square meters does steel roof of steel structure workshop need?
Different span, the cost per square is not the same, the budget should first look at your program map, and then according to the current steel prices to make a budget, probably 350-1000.
Q:202 stainless steel wire can pass 200 hours salt mist test?
202 stainless steel wire can not pass 200 hours salt mist test, 202 stainless steel is one of 200 series stainless steel, the national standard model is 1Cr18Mn8Ni5N. 200 series stainless steel is low nickel, high manganese stainless steel, nickel content, manganese content of about 8%, is a nickel type stainless steel. Stainless steel passivation solution can be used to improve the rust resistance and corrosion resistance of stainless steel, improve salt spray test time, should not change the physical appearance of the workpiece, size and conductivity and other physical properties.
Q:How to distinguish 301 stainless steel wire, soft silk, hard silk?
Soft and hard testing is usually surface hardness tester or material extension test can be detected!
