Welding method of 506 electrode
Welding method of 506 electrodeJ506 is a low hydrogen potassium electrode, it is a kind of basic electrode, welding steel structure can be several typical Q235 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.
506 is AC and DC electrode, but it is better to use dc. With AC welding machine, the no-load voltage can not be too low, otherwise it is easy to stick the strip.
1) 506 electrode belongs to alkaline electrode arc difficult than 422 welding than AC welding machine easy to weld some DC welding machine, welding should be placed in the drying oven, oven temperature should be adjusted to 350 degrees Celsius, the time for an hour or so. Welding by DC reverse welding. The difference between DC welding machine and welding machine AC DC welder is a rectifier to convert AC to DC, thereby eliminating the change of current polarity and size, increase the stability of welding arc, eliminating the arc welding process of arc and arc, the probability of defects reduces the welding process. To improve the quality of welding.2) direct current reverse welding is adopted in DC welding machine to adjust the reasoning current and arc current properly3) from the arc to pores is due to magnetic blow by, can add the arc plate and arc welding at the same time to solve information, pay attention to the arc angle and arc length control. Also, the ground wire is best placed in the middle of the weldment.4) welding parts should be removed before welding, such as oil pollution, rust, moisture and other impurities. Otherwise, porosity and other welding defects are easy to occur.5) welding short arc, current not too big. If you solder a box of electrode, you will feel no difference with 422, very good welding.6) after welding the arc, do not artificially break the arc. It is better to finish welding all the electrodes, and do not stop in the middle. Such as the arc breaking again after arc welding rod will stick in the weldment, this time you need to put on the ground electrode is inserted, the medicine skin electrode core removed exposing the middle, that will be good to the arc again.
