Q:What is the national standard for TIG welding of tungsten stainless steel?

There are three inspection standards for any welding:1, surface examination, the main test whether there are edges, surface cracks, surface pores and slag inclusion;2, nondestructive testing (such as RT, UT, MT) detection is mainly superficial and internal as well as the root of all welding defects, such as porosity, crack, internal slag, burn, incomplete penetration defects etc.;3 、 final pressure test (strength, pressure and tight pressure), whether or not the weld is leaking.Inspection standards are mainly based on design documents and standards and specifications: such as the transmission of toxic, harmful, flammable medium pipes, welding requirements nondestructive testing, I level or II level qualified, standards are different

Q:Our factory is now using ER50-6 wire gas shielded wire made from Shandong cable to do carbon dioxide and argon arc welding wire:1, using ER50-6 as carbon dioxide welding wire, the use of the condition is about 1.5 of the hot plate or cold plate, welding equipment shell, suitable?2, do argon arc welding wire with ER50-6, use condition is welding 0.8-1.5 of cold plate cylinder, after welding the cylinder still need to carry on two sides drawing and expanding, is ER50-6 suitable? Is there a more suitable welding wire to ensure that the expanding cylinder does not fuse? Please recommendThe second question is especially important. Please give your advice. StopThe mechanical properties of the ER50-6 were found to beTensile strength (b = 500MPa), yield strength (0.2 sigma) = 420MPa, elongation (5,%) = 22Deep drawing requirements, if the elongation is greater, the more suitable for welding wire?

The first problem is that ER50-6 is a solid welding wire. It is used in argon arc welding. How can CO2 be used to protect it? I don't think so!The second question, no one can guarantee you this safety problem, only you can see the performance of the parent material to choose.

Q:607 what is the material of welding wire?

Flux cored wire of DY-YJ607 (Q) base slag system. Good mechanical properties, low diffusible hydrogen content, suitable for welding of 60 kg class high strength and high toughness steel.Mainly used for chemical equipment and various mechanical equipment surfacing welding repair parts. Such as metallurgical machinery, mining machinery, turnouts, jaw plate, shovel, shovel, ship machine reamer, quarrying engineering, spiral mixer blade and fan blades, processing machinery, engineering machinery, building materials machinery etc..

Q:What is the problem of welding when the material is different from the wire?

1, in most cases, the material of sheet material and welding material is certainly not the same, there is no comparability.2 plates are usually made of flat rectangular building material boards of standard size, used as walls, ceilings, or floors. Also refers to the forging, rolling or casting of metal plates. It is divided into thin plate, middle plate, thick plate, thick plate, usually flat rectangular building material board.3, welding wire is used as filler metal or as a conductive wire welding material. In gas welding and gas tungsten arc welding, welding wire used as filler metal; in submerged arc welding, electroslag welding and MIG arc welding, welding wire as filler metal, and conductive electrode. The surface of the wire is not coated with anti oxidizing flux.
