Q:What is the JISAWS standard and certification of welding wire?
Is referred to as the two national standards, the equivalent of "GB", the specific content, AWS more perfect, the international general particularly strong (who is welding material, usually printed on the packaging), JIS is weak, but he has added some varieties in some material on the subject, or use the AWS request.Specific content, you can search the internet.
Q:Can gas shielded welding welding aluminum welding wire?
You can put the wire into U, rotation gear, wire feeding hose for Chengtefurong, gun into the water. That's it.
Q:Argon arc welding how to continuously feed wire, the head of the welding wire will not sway.
Isn't there an automatic wire feed?
Q:What welding wire for F22 valve steel and 12Cr1MoV pipe welding?
The welding process is complex and needs to be evaluatedPreheat the whole or part of the weld before welding, guarantee the preheating temperature 250~300 degrees within the range of 150mm on both sides of weld, and the temperature between layers shall be within the control range of preheating temperature.GTAW (pure Ar gas protection): it is recommended to adopt TIG-R31 (including V) welding wire, diameter 2.5mm, current 100 ~ 140A.If there is a certain wall thickness, the pipe diameter is not very small, it is recommended to take GTAW+SMAW.SMAW: the welding rod adopts R337, and the specifications can be determined according to the actual situation.After welding, clean splash, heat up to 350~450 degrees, keep warm and cool after heat.12Cr1MoV best use of the corresponding components of heat-resistant steel electrode, such as R310, R312, R317, R316Fe, preheating 250~350 degrees before welding, welding tempering treatment 710~750 degrees.
Q:What is the difference between 321 wire welding and 304 wire welding?
What is the composition?
Q:Silver wire with silver content for copper welding
Is it silver soldered? I know only lead and zinc welding wire, lead is 63%, welding temperature is generally 280-350 degrees. Exports to Europe now require lead-free soldering, of course, welding temperature, process tools are not the same.
Q:What is the advantage of welding wire without copper plating?
No sewage discharge, no copper smoke, small splash, small smoke (no copper smoke), molding, environmental protection, energy saving.Expand:The main purpose of copper wire welding is corrosion protection, because the main component of the wire is steel, and the bare leakage is easy to rust and corrosion in the atmosphere. The surface coating of copper can effectively prolong the shelf life. Furthermore, electrical conductivity can be enhanced.Welding wire is used as filler metal or metal wire welding material at the same time as conductive. 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.
Q:What is welding wire? How to translate welding wire?
A metal wire that is used as a filler metal and used to conduct electrical welding at the time of welding. There are two kinds of solid welding wire and flux cored wire.
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:Who knows the C02 gas shielded welding gas and wire consumption ratio?
Depending on how you solder it, use a bottle of gas a day
