Product Description:

1.Welding Wire Description:

A mild steel MIG welding wire containing higher silicon and manganese additions designed to improve welding. The higher silicon content helps to reduce the molten metal surface tension, resulting in flatter weld bead profile with less spatter The precisel.

Applicable for single pass and multi-pass welding of carbon steel and 500 MPa grade low alloy steel and is widely  used  in such fields as automobile industry, construction machinery manufacturing, ship building,  metallurgical and mining equipment manufacturing, bridge building, petrochemical industry and pressure vessel manufacturing, etc. Also applicable for high-speed welding of sheets and pipeline steel.

2.Main Features of Welding Wire

1. It has excellent mechanical performance such as fast melting rate, high depositing efficiency, stable arc, little spatter, beautiful seam. 

2. The slag is fluid and when hardened it is compact and easy to remove 

3. It is suitable for all position welding of steel sheets and irregular joints even under unfavorable conditions.

4. High-speed welding of light gauge plate and pipe line steel.

5. Certificates: ISO9001,CE,TUV

Q:What welding wire do 15CrMo and 1Cr5Mo use?
Welding wire, H05CrMoTiR welding rod, R307, welding wire, H13CrMo welding rod, R307, or welding wire, TIG-R40 welding rod, R507
Q:Is it suitable to use gas shielded welding wire ER50-6 as argon welding wire and carbon dioxide welding wire?
ER50-6 is originally one of the most commonly used carbon dioxide welding wire, the elongation is great, of course, argon arc welding is not good, you change to ER55-B2 or ER55-B2-Mo will do.
Q:What welding wire does 5A06 use?
ER5356Generally speaking, that's enough
Q:What does "free cleaning" wire mean?
Cleaning wire is usually large container group use, we usually use welding rod, welding with electrode, there is a row of oxide skin to go out, and welding wire is not used, can save a lot of time
Q:What kind of wire welding carbon steel material does not crack in argon arc welding? Please explain in detail. Thank you!
Cracking is a raw material problem, and it doesn't have much to do with welding wires. Heat the workpiece in the oven and weld it...
Q:Argon arc welding how to continuously feed wire, the head of the welding wire will not sway.
To straighten the wire, and then with the middle finger and index finger grip, by stretching two finger feeding wire
Q:What wire is H08A? What wire is GB? What wire is HJ?
H08A is carbon steel welding wire, GB is national standard Pinyin abbreviation, HJ is flux (smelting flux), for example.H08A welding wire can be welded with HJ431 flux Q235.
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:Base metal Q235, thickness 4-30mm, welding wire H08C, T type welding, argon rich gas shielded welding. What is the energy of welding line?
You mean his current or voltage?
Q:What welding wire is used for argon arc welding of 201 stainless steel tube?
201, water can be, but after welding, welding seam on both sides of the nickel burning, long time will rust, cracking, so it is best to use 304 wire,
