- Q:How thin is the smallest electrode?
- The smallest electrode is the diameter of the electrode (mm) 1.6, the welding current (A) 25~40.
- Q:Add 100 points to the approved answer before 2, plus 50 at 3. Beg speed
- E5015: belong to low hydrogen sodium basic welding rod, direct reverse welding.J507:J507 (J48.57) conforms to GB E5015, equivalent to AWS E7015Description: J507 is a low carbon hydrogen type stainless steel electrode. Direct current reverse welding can be carried out in all position welding. With excellent welding process performance, stable arc, less spatter, easy to remove slag, the deposited metal has excellent mechanical properties and crack resistance, low temperature resistance, good impact toughness.Usage: used for welding of carbon steel and low alloy steel structure important (compression and dynamic), such as 16Mn, 09Mn2Si, 09Mn2V, B, A and marine D, E grade steel, also used for welding carbon steel plate and poor weldability.Chemical composition of deposited metal (%)chemical compositionC = 0.12Mn = 1.60Si = 0.75S = 0.035P = 0.040Ni = 0.30Mo = 0.30Cr = 0.20V = 0.08Diffusible hydrogen content in deposited metal: 8.0ml/100g (glycerol)Reference current (DC+)Electrode diameter (mm)2.5.3.2.4.5.Welding current (A)60~10080~140110~210160~230Matters needing attention:The electrode is subject to 300~350 C 1H 1 before welding with baking, drying with.The welding must remove impurity welding rust, oil, water etc..3 be short arc welding operation, narrow welding bead.
- Q:Where is the difference between 422 electrode and E50 electrode? HRB335 steel cage can use 422 electrode
- Tensile strength is mainly different, HRB335 steel bar should be allowed to use 422 electrodes,
- Q: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?
- 1, welding current is too small.Please refer to the instruction of welding current in electrode box, choose the suitable welding current according to the welding position.2 basic electrode welding with AC welder.J426, J506 and other low hydrogen potassium welding electrodes must be welded with BX series alternating current welding machine with no-load voltage above 70V. The lower the no-load voltage of the welder, the easier it is to stick the welding rod.3, the welding rod model is wrong.J427, J507 and other low hydrogen sodium welding rod, unlike low hydrogen potassium electrode containing arc stabilizer, the welding rod must be welded by DC welding machine. AC welding machine will stick welding rod, cannot arc.4, improper operation. Basic electrode (low hydrogen potassium welding rod, low hydrogen sodium welding rod, etc.) shall adopt the method of striking and striking arc. Just as a match, the end of the welding rod and the construction of contact, a slight rub can ignite the welding arc. If the direct striking method is used, the welding rod is unavoidable.5, technical problems. The arc welding rod should lift the arc 1-3 millimeters rapidly and enter the normal welding mode. Otherwise, long time welding rod and workpiece short-circuit will dip electrode.
- Q:Electrode: 506--J48-56 junction, Tianjin Bridge Welding Materials Group Co. Ltd. production. Is it possible to use an AC welder?
- J506 welding rod, using DC welder, AC welder can.
- Q: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.
- Q:Generally, how many packs are in one case and how many KG in one package?
- A case of four bags, a packet of five kg
- Q:How to use hot 317 welding rod?
- R317 is a low alloy steel welding rod with low sodium hydrogen type. It can be welded in all positions by DC reverse welding, and the welding process is good. The weldment should be preheated to 250~300 DEG C before welding and should be treated at 700~740 DEG C after welding.The electrode (coveredelectrode), is the metal coating in the welding core (coating), uniform centripetal pressure applied to core. The electrode consists of two cores and coating composition. The different cores are also different. The core components directly affect the composition and properties of the weld metal, so the harmful elements in the welding core to as little as possible.
- Q: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;
- Q:What brand of carbon steel electrode is the best?
- Jinqiao, bridge, the Atlantic,
