FAQ

Types of electrodes

Ask me, the welding rod according to the diameter commonly used has 2.5, 3.2, 4. According to the use of ordinary, stainless steel, cast iron, wear-resistant electrode. Among them, the ordinary electrode according to grade 422506 and 502, stainless steel 102, 132, cast iron points 302, 402. Electrode wear is generally used in digging bucket, carbon and some high wear resistant. These are commonly used welding rod, and some special electrode, the amount is very small. Generally speaking, the higher the grade of the electrode, the more expensive the price. Little dragon, what else do you know? Ask me!

What type of welding rod is needed for the construction of three grade steel bars used in construction?

Go to the specifications, and the material list has a given name, such as 1499.2-2007

What's the difference between 507 and 422 electrodes?

The main difference is the intensity, a difference; another 507 are low hydrogen alkaline electrode, DC reverse; 422 is an acid welding rod, AC and DC dual-use

When welding, the welding rod sometimes can easily stick to the weldment, and it is not easy to arc. The ignition is also easy to extinguish. Why is that? What happens when this happens?

There are several kinds of current, small hand, unfamiliar, 506 and other special welding rod

How do you know it's a white steel electrode?

White steel electrode, stainless steel electrode is generally refers to many kinds of stainless steel, such as 30403-30408, 32310S, 31603, 31608, 1CR13 and so on, using different types of electrode, stainless steel electrode used in general are: 102, 022, 132, 042, 002, 132 different types of.

When welding, for example, 3.2 of the electrode should choose how much current

Empirical formula: welding electrode current = 30~55 times of electrode diameterSelect the base material thickness

What kind of material is the drill pipe and what kind of electrode?

Oil drill pipe is a high carbon steel material, using WEWELDING 600 welding.Selection of electrodes of 3.2 mm diameter welding current, in 100-120A, the cold welding welding process can be.Application of WEWELDING600 special alloy steel welding rodSuitable for welding of tool and mould, high-speed tool steel, hot work tool steel, steel, cast steel, T-1 steel, Nai Zhengang, vanadium steel, spring steel, martensitic stainless steel, austenitic stainless steel, ferritic stainless steel, and the unknown as well as between the various different types of steel welding etc.. Such as high pressure valves, broken bolt clearance, shaft transformation, etc., the effect is very satisfactory.Technical parameters of WEWELDING600 special alloy steel welding rodTensile strength: 125000 psi (862MPa)Yield strength: 90000 psi (620MPa)Elongation: 35%Hardness after welding: HRC23 (work hardening up to HRC47)Power supply: AC and DC dual use, DC DC reverse connectionProcess parameters of WEWELDING600 special alloy steel electrodeDiameter (mm) Phi 2.5 Phi 3.2 Phi 4Current (Amperes) 40-80, 65-120, 90-150Packing weight (LBS) 222Applicable technology of WEWELDING600 special alloy steel welding rod1, WEWELDING 600 alloy steel electrode (referred to as WE600 or Wiodin 600 electrode) has very favorable thermal expansion and cold shrinkage, can make cracks and distortion minimum.2, it is an ideal choice to lower the weld seam when welding the metal which is sensitive to the crack.3, with thick parts, forming a 90 degree V groove.4, welding high carbon steel before preheating 200 degrees; welding spring steel to control the welding temperature, in case the spring softening.5. Maintain a short arc length and use a narrow bead to prevent overheating.6, before removing slag, let the welding site cooling.

What's the type of electrode used for 304 stainless steel?
