E9015-B9 is a welding rod for which steel is welded
- Should be chromium, molybdenum, heat-resistant steel welding rod, E9015 means the meaning and structure of steel welding rod means the same significance, B9 is CrMo chemical composition code.s
What type of welding machine does not use electrode welding machine?
- In addition to all the outside welding manual welding and manual welding AC DC do not need electrode, such as argon arc welding (filler wire or wire filling), gas welding (CO2, MIG, MAG), submerged arc welding, resistance welding (spot welding, projection welding, seam welding, butt welding), laser welding, diffusion welding, explosive welding, plasma welding, diffusion welding, brazing, etc..s
Where is the difference between 422 electrode and E50 electrode?
- E50 welding rod has E5015, that is, J507 E5016, that is, J506, good crack resistance, HRB335 steel can be weldedJ422 or E4303 is low carbon steel welding rod, steel bar will cracks
Can ordinary 422 electrode welding pig iron?
- Not welding, easy to fall off after welding, resulting in more defects more defects. Can use cast iron welding rod Z308, the worst to use A302.s
What welding rod should be used for welding between No. 20 and No. 45 steel?
- J427When welding, pay attention to the small current at the bottom, and the weldability of No. 45 steel is poors
How much is the angle between the horizontal fillet welding, welding and butt welding?
- A flatThe angle between the welding wire and the welding torch is kept at about 90 degrees;Two. Vertical weldingThe welding torch shall be tilted upwards along the welding direction, and shall be maintained at 60--80 degrees in general with the weldmentThree, transverse weldingThe left welding method is adopted for the thin part. But the welding torch should also be tilted upwards so that the flame will flow directly towards the weld seam. The molten metal will be prevented from flowing out of the molten pool by the pressure of the airflow;Four. Overhead weldingWhen welding the first layer of the weld seam with groove, the welding rod is 90 degrees to the sides of the groove. With the welding direction of 70 - 80 degrees angle, with the shortest arc to do push and pull action, the pool should be thin, not thick, and to ensure good fusion with the base metal. When the bath temperature is too high, the arc can be lifted, and the temperature will be slightly lowered. When welding all the other layers, the welding rod will swing and make the arc stabilizing action on both sides.s
When 507560 electrodes are used at the same time, which electrode should be selected?
- 1, J506 welding rod, J507 are basic electrode.2, J506 welding rod can be AC and DC dual-use.3, J507 welding rod can only use DC welder.4, if there is no DC welding machine should use J506, if J506 arc difficult, you can consider using J502.5, J507 welding rod crack performance is better than J506.s
What type of welding rod is applied to Q345 steel plate?
- Q345 steel plate is welded with J506 or J507 electrode.J506 is a low hydrogen potassium electrode, it is a kind of basic electrode, welding steel structure and the typical Q235, Q245R, Q345 steel, the tensile strength of E4315 is much larger relative to the common electrode, so the general welding force or by welding steel structure of dynamic load.J506 welding rod diameter ranging from 2.5mm to 6.0mm, can be carried out in all position welding, welding using alternative welding machine.The weld formation after J506 welding is more difficult than that of the acid welding rod. If an electrode is used on the cover of the steel structure, the acid electrode can be used.J507 is a low sodium hydrogen electrode, it is a kind of basic electrode, can be Q235, Q245R, Q345 typical welding structure steel in steel, the tensile strength of E4315 is much larger compared to the common electrode, so the general welding force or under dynamic load of steel structure.J507 welding rod diameter ranging from 2.5mm to 6.0mm, can be carried out in all position welding, welding using DC welder, polarity reversal. Of course, if there is only AC welder in the field, AC welder can be used, but the current needs to be switched on.The weld formation after J507 welding is more difficult than that of the acid welding rod. If an electrode is used on the cover of the steel structure, the acid electrode can be used.s
