Projection Welding Diagram

The projections may have different shapes for design or strength purposes. Schematic Resistance Spot Welding Process Source Scientific Diagram.

Spot and Projection Welding - Artech Welders Private Limited took roots in 1994 with the dream of manufacturing Capacitor Discharge CD projection welding machines.

Projection welding diagram. Projections need not be round. Weld Current is the current in the welding circuit during the making of a weld. Second the current control determines the.

The amount of weld current is controlled by two things. 14 or 15 can be made by forming projections in. High localized temperatures are generated at the projections which are in contact with the flat.

Weld Welding Insulator Electricity Stored Energy Capacitor Discharge Welding Machines Manufacturer Supplier Ludhiana Nut. Short length T joints eg. Projection welding is a resistance welding process of joining two sheets or a sheet and a thick component or a small component like nut to a big body like automotive chasis by making raised portions or projections on one of the components where weld nugget is required to be made.

Projection welding is an ideal method of fastening attachments eg. Powered by a vision to blend power saving with aesthetics Artech has today germinated into a force to reckon with in the field of resistance welding. Where the weld cycle is repetitive control set on REPEAT.

It is named so because different projections are formed on the workpiece for effective welding. Diagram of projection welding. Projection is a type of resistance welding.

Diagram Of Projection Welding The weld cycle remains same and on passing current all projections will heat up and get welded. Projection welding is a variation of resistance welding in which current flow is concentrated at the point of contact with a local geometric extension of one or both of the parts being welded. A little quantity of pressure can be applied throughout the electrode on welding shields.

Projection welding is commonly used for sheet metal fabrications. A projection welding is a resistance welding where high electrical resistance at the joint is developed by embossing one or more projections on one of the surfaces to be welded. Conventional spot welding involves passing a high tension electric arc between two electrodes on either side of the material to be welded.

In this welding process the design or shape of the part is used to make discreet individual contact to concentrate the current during the welding process. First the setting of the transformer tap switch determines the maximum amount of weld current available. This article focuses on the process fundamentals advantages and limitations of projection welding and reviews the equipment used in the process.

Under the welding pressure the projections flatten allowing the two surfaces to be joined to come together. This causes localized melting of the two materials thus creating a spot weld. At present the work parts held among electrode as well as a huge quantity of current flow through it.

They can be of any shape. The melted projection becomes the weld. Circuit Diagram Of Projection Welding Machine.

PDF circuit diagram files of SOHAL brand Mig welding Tig Welding Spot Welding Projection Welding Seam welding Metal Gathering Plasma Cutting Resistance and. Brackets spigots and weld nuts to sheet metal where there is access from only one side and for making attachments to solid forged or machined parts.

Metal fibre welding can be used for welding dissimilar metals for example copper to stainless steel copper to brass and stainless steel to a ferrous material can be successfully welded by this method. Projection welding is similar to spot welding apart from a dimple can be generated on work parts at the place wherever weld is preferred. Build Portable Dc Arc Welder Mother Earth News.

The welding current is passed through the joint the welding heat is generated at these projections. Metal fibre may consist of any desired alloy in the form of a thin sheet which is placed between two sheets of metal and is projection welded in the usual manner as shown in Fig. Construction and working of projection welding.
