FAQ

Please tell me the current corresponding to various types of welding electrodes in detail!

Sectional area of electrode x15Such as 4mm welding rod, =2x2x3,14x15=180

What kind of welding rod is used to weld Mn13 steel plate with ordinary high quality structural steel?

The basic ingredients are steel, and the liquid flux can be produced by solid light. With the brass welding rod (copper, zinc and tin alloy), the brazing effect can be very good.

Cast 308 pure nickel cast iron welding electrode. What shall be used for welding?

Usually used for welding of grey cast iron is better than the ordinary structural steel electrode or stainless steel electrode strength, generally used for welding cast iron of ordinary civilian, industrial equipment if it is real iron, cast iron material is unknown, strength demanding case suggested that welding using WE777 special cast iron electrodeApplication of WE777 special cast iron welding rodSuitable for the full range of cold welding welding, welding cast iron base material can almost all, and it is easy to achieve cast iron and carbon steel dissimilar metal welding, such as solving matrix fracture, crack, wear, hole filling defects after welding can be machined, many applications in the engine casing, cylinder head, casting machine, gear base the tooth of iron castings.

What kinds of welding electrodes are used in the copper tubes for air conditioning? What's the difference?

There are silver electrode and two electrode containing phosphonium, the former used in high sulfur environment, the price is about 3 times higher than the latter.

What is the welding process of duplex stainless steel 2507? What electrode?

The brand of welding rod is: 2209. The electrode must be dried before welding. The drying process is 2 hours at 250 C, and the welding rod must be insulated with electrode.

Excuse me: can J422 welding rod not be used for HRB335 steel bar welding? Where there is such a rule, I see the norms can use ah.

JGJ18-2003 regulations for welding and acceptance of reinforcing steel bars 3.0.3:HRB335 in the case of bar welding and lap welding, the use of E4303 (GB/T 5117, E4303), both CHE422, that is, commonly known as J422.Table 3.0.3 provides as follows

Hand welding electrodes 3.2 and 4 which are more commonly used?

Personally think 3.2 is more commonly used.The welding between the sheet metal parts, the weld is not big, 4-5mm, 3.2 of the running better.For wider welds, 4 is recommended;

What's the difference between 422 and 506? What are their respective attributes?

506 electrodes and 422 electrodes, in addition to the strength level, the former is 50 kilograms, and the latter is 42 kg class,506 electrode for low hydrogen alkaline skin, although it can be AC and DC dual-use, but the best use of DC welding machine422 electrodes for calcium titanium acid skin, AC and DC can be
