Welding method of welded reactor iron yoke

The invention discloses a welding method of a welding type reactor iron yoke. The welding method comprises the following measures: manufacturing a clamp which can be repeatedly used and is used for filling iron chips; prefabricating a welding part; the cut iron core pieces are stacked in a clamping groove of a clamp according to the U-shaped frame part and the gland part and pressed tightly, then welding pieces are welded to the iron core pieces of the U-shaped frame part and the gland part on the clamp, and press fitting is conducted on the welded U-shaped frame part, the gland part and the coil. The reactor iron yoke welding clamp has the advantages that welding parts do not need to be specially machined, only profiles need to be cut, stacking of iron core pieces is facilitated, welding can be directly carried out on the clamping groove body, the welding process of large and heavy reactor iron yokes is simplified, and the welding efficiency is improved; the welded reactor iron yoke can avoid tapping of the
