Projection Welding Copper Electrode

Unlike resistance spot welding where electrodes grow in the contact area diameter as they degrade projection welding electrodes do not experience this. When the projection is totally collapsed further growth of a weld nugget will be impossible since the large surface of the copper electrodes will diffuse current density when the electrodes make full contact to the work piece.

Projection welding copper electrode. To meet the various requirements of the customers we are involved in offering a wide assortment of Copper Projection Welding Electrode. Refractory electrode materials such as tungstencopper tungsten or molybdenum are used for applications such as projection welding inserts where the electrode contact area is at least three times the weld size. In arc welding an electrode is used to conduct current through a workpiece to fuse two pieces.

Electrode materials are tungstencopper and beryllium-free class III copperboth display the formation of an oxidized alloy surface layer and pitting as weld number increases. Schmidt has the projection-welding caps and electrodes for your system whether youre looking for standard shapes and sizes or custom pieces for special applications.

Air pressure type nut welding electrode assembly are available. The 70 value in a resistance welding standardspecification is typically associated with the projection welding of coinedforgedsolid weld nuts. Spot seam and projection welding Spot seam and projection welding are carried out by electric resistance heating two overlapping metal parts which are pressed together by copper or copper alloy electrodes.

Equipment used for projection welding is similar to that used for spot welding except that the rod electrodes are replaced by flat copper platens or dies as shown in Fig. Stud welding electrodes and backup electrodes are available for stud 6mm to 12mm. In projection welding copper electrodes are used as copper is a very good conductor of heat and electricity.

Sometimes projection welding will be used to avoid damage to one of the work piece surfaces due to the fact that flat electrodes are used in this process.

These materials have higher hardness but lower conductivity than the Class 2 electrodes. Projection welding electrodes typically cover a larger area compared with spot welding electrodes and are used to weld nuts bolts or other fastening assembly to other metal parts. The two metal pieces which are to be joined are kept between two elctrodes and the electrodes are kept between the platens as shown in the figure above.

Projection welding is a type of resistance welding that focuses current and force to a single point or line at the beginning of a weld. For context the embossedstamped projection welding requirements detailed in both the RWMA Manual and the AWS C11 only state what sort of weld strength is required not the required weld size. Let us know what your electrode looks like and we are able to machine it according to your drawing or sample.

Usually two or three projections are welded at the same time. Especially Capheads are available with tungsten copper faced to give more life to electrodes. One of the main differences between conventional sheet-to-sheet resistance welding and projection welding is that projection welding is a dynamic process involving considerable movement of the upper electrode.

Local melting occurs at the faying surfaces and an internal weld nugget is formed. Guide pins are made hard steel with coating along with coated insulating sleeve. Contact us with a part number or fastener size and stamping hole diameter for more details.
