Q:Does the dual purpose welder not use gas directly with welding wire?

Welding machine can be done without gas directly welding wire, but can not weld ah.

Q:What is the abbreviation of wire ER?

ER is the American Standard

Q:Then some of them use 201 stainless steel wire, like this wire, about how much is one kilogram?

Stainless steel welding wire

Q:What wire is H08CrMoVA H13C rMoA what wire is it?

H08CrMoVA Description: the weld metal is used in the high temperature environment, and the welding seam has better strength at medium and high temperature.Application: it is used in welding 12CrMoV, 15Cr1MoV, ZG20CrMoV, etc., and is used in welding of heat-resisting steel, pressure vessel and pipeline. Used for reheat steam heating section pipe and low pressure bypass pipe of steam turbine.H13CrMoA welding of 15CrMo and ASTM, A387Gr.11, Gr.12 and other heat-resistant steel pressure vessels and pipes.

Q:Two welding machine, 1 of the welding wire into 1.2 of the need to change where?

The welding torch changes the electric nozzle, the wire feeder changes the wire feed wheel.Welding torch, electric nozzle, 0.81.0 dual-use, need to replace wire feed wheel.The conductive nozzle is 1.01.2, which is used directly in the feed rotation surface.A 1.2 mm tip (tip diameter than the wire diameter 0.02 mm, the actual tip diameter of 1.22 mm diameter) conductive nozzle wear too much need to replace the nozzle.

Q:Does argon arc welding thick material need no welding wire?

Argon arc welding is not like welding, welding electrode itself is filling material, argon arc welding is no filling material. Argon arc welding stainless steel without welding wire is formed by melting the base metal. Such as two stainless steel butt welding wire, in no case, two pieces of plate must be no gap, when the tungsten needle alignment weld produced high current that produce high temperature, the two panels are also melting, loosen the gun switch after the melting of stainless steel water condenses together welded together, if we must have with the wire.Summary: no welding wire welding workpiece can solder together must leave, if even only 0.5mm are difficult to weld, first after welding, the welding, the welding speed should be uniform, without wires, not large current about 20A, from the middle to both sides welding. After welding, the main point of non deformation is that the plate should be docked and added at least 1 centimeters a point. The copper lining under the condition plate is best, and the weldment can be placed on the platform or made as a fixture. Speed must be fast, the more slowly, the more deformation.

Q:304 what wire?

Solid welding wire ER308Flux cored wire E308Welding rod A102The above material price

Q:What gas welding flux cored wire?

Flux cored wire must be welded with carbon dioxide, because flux cored wire is divided into four types: self protection, gas protection, gas self protection and other forms of protection. The self shielded welding wire is protected by the chemical reaction of the powder at high temperature to produce gas and slag, and this type of welding wire can be welded without additional protective gas.Flux cored wire is not equal to the combined gas and slag protection, does not apply to the field or windy conditions. However, the flux cored wire for welding pool melting than solid wire. Because solid wire components often encounter the phenomenon of uneven, resulting in stomatal flux cored wire. But this phenomenon does not exist. Stomatal probability is reduced. Other theories on the cored wire is better than the mechanical properties of weld solid wire. But the flux cored wire manufacturer quality uneven in quality by using flux cored wire, need to take more risk.Flux cored wire production is to reduce the cost and not caused by the chemical composition of welding wire is mainly silicon manganese content fluctuation. So whenever possible. Do not use flux cored wire

Q:What welding wire for F22 valve steel and 12Cr1MoV pipe welding?

F22 belongs to Cr2.5% Mo1% heat-resisting steel,12Cr1MoV belongs to the F11/P11 (Cr1% Mo0.5%) 2 kinds of heat-resistant steel, welding material should be used if the F22 welding material, welding wire GB ER62-B3 American Standard: ER90S-G/ER90S-B3

Q:I am the manufacturer of stainless steel welding wire, and I have been asked by the customer - stainless steel wire outlet customs code. I do not know, please know the friend told me, I will be very grateful.
