Q:Why can not welding machine welding electrode spark?
Cause and treatment of welding rod welding spark:1 、 welding current is too small. According to the type and diameter of the electrode used, the welding current shall be explained with reference to the electrode packing box.2 、 the ground wire is not clamped and the ground contact is bad. Check the cable joint firmness with a special ground clamp.3, the surface of the work has greasy dirt, embroidery scale paint, water and other impurities, affecting the electrode conduction. When striking, striking or striking the arc, the instantaneous resistance is greater. It can produce instant sparks, lift the arc, and then rub out the workpiece with an angle grinder, exposing the metallic luster.
Q:Is the electrode of E43 and 422 of electrodes the same?
E43 welding rod is the national standard GB/T5117-1995, it is the type of representation, 422 should be J422, is the brand of the method of expression.E43 electrode E4303, he is J422 welding rod. If it's E4315, he's the J427 electrode. To weld Q235B seamless steel tube, using E4315, that is, J427 is better. His impact toughness at low temperatures is higher than that of J422. But it needs DC welding machine welding, if the requirement is not high, J422 can also meet the Q235B seamless steel pipe welding, power supply is widely used, AC and DC 2 use.
Q:When welding, for example, 3.2 of the electrode should choose how much current
The current selection depends on the thickness of the steel plate welding you, if it is a few thick milimeter can use 150A 200A to 10 mm thick, can use 180A to 250A.Pu steel plate for large current will be easy to wear thick steel plate welding, welding with small current will not!
Q:How much is the electric welder with 4 mm electrode?
Answer: We specialize in the production of welding machine.If not for a long time, buy 250A welding machine, about 1800. If the factory for a long time, should buy 315A welding machine, about 3500.
Q:Difference between J422 welding rod and J502 welding rod
J422 welding rod is mainly used for welding low carbon steel structure and low strength low-alloy steel, such as A2, No. 20 steel, No. 35 steel, etc..J502 welding rod is mainly used for welding low strength carbon steel structure and alloy steel, such as A3, No. 45 steel, 16Mn and so on.J422 welding rod and J502 welding electrode are common terms, corresponding to international standard brands are E4303 and E5003 respectively. Is a kind of acid electrode, titanium calcium coating, J structural steel electrode, 42 and 50 respectively, the tensile strength of the weld metal (more than 420MPa and more than 500MPa), said 2 electrode for all position welding (welding, welding, overhead welding, horizontal welding).
Q:Question Q235 weldability of carbon steel. What are the welding characteristics of those electrodes?
Acid, alkaline welding rod can be. The acid welding rod E4303 has the advantages of good manufacturability, easy operation and poor mechanical performance. The basic electrode E5015 has poor mechanical properties and needs a DC welding machine with good mechanical properties.
Q:J422 electrodes are marked with "THJ422". What does TH represent?
J422 is the brand of welding rod GB. As for the TH is the enterprise stipulated grades, the first letter T should be on behalf of the welding electrode (strip of the first letter); second letters H, should be related to the electrode trademark or manufacturer's name.
Q:How to weld iron castings? Which welding method is adopted? What kind of electrode? What is the specific operation process? If possible, please give examples.
The welding of cast iron parts is made of cast iron special electrode, that is to say, pig iron welding rod. Because the iron chemical and physical properties are special, so the welding conditions of iron castings are higher, first of all to butt welding parts for heating, heating speed is not too fast, slow heating, heating temperature to about 60-70 degrees can be welded (conditional temperature can be higher) the best welding in thermal insulation under the condition of welding method with ordinary welding, the welding is good, after completion of welding to insulation, generally use the workpiece buried in lime powder in thermal insulation. For reference only.Hot dip galvanizing of zinc. Shen Jianfu
Q:What kind of welding rod does 1Cr13 steel plate use?
Usually in 1Cr13 and other dissimilar materials welding, choose A302 welding rod, welding should not preheat and after heat, but after welding, it is best to increase heat treatment (of course, no heat treatment is also no problem)It is better to use G202 or G207 if welding of 1Cr13 same kind of material, preheating before welding, heat after welding and heat treatment
Q:What kind of material is E4303 electrode?
The utility model belongs to an acid welding rod, and is suitable for alternating current and direct current welding machines. Generally used for welding ordinary steel.The model E indicates the electrode; 43 indicates that the tensile strength of the weld metal is no less than 430MPa; 03 represents the titanium calcium based coating; it is suitable for AC and DC power supplies. Perform standard GB/T5117-1995 carbon steel electrodes
