How to Spot Weld Copper | eHow

Spot welding is a process by which the surfaces of two metallic pieces are joined together through heating. The heat that melts the surfaces is generated by an electrical current. Copper is a highly conductive metal, often used as the metal of the conducting electrode ends of spot welders, complicating the process of spot welding it.

Spot welding - Wikipedia

The process uses two shaped copper alloy electrodes to concentrate welding current into a small "spot" and to simultaneously clamp the sheets together. Work-pieces are held together under pressure exerted by electrodes. Typically the sheets are in the 0.5 to 3 mm (0.020 to 0.118 in) thickness range.

What is Spot Welding? (A Complete Welding Process Guide) - TWI

A form of resistance welding, spot welding is one of the oldest welding processes whereby two or more sheets of metal are welded together without the use of any filler material. The process involves applying pressure and heat to the weld area using shaped alloy copper electrodes which convey an electrical current through the weld pieces.

Spot Weld Anything (Even Copper)! : 7 Steps (with Pictures ...

Anyone who's tried will tell you copper is a pain to weld- for many of the same reasons you probably *want* to be using it in your project. It's got about five times the thermal conductivity of iron, which basically means you need to pump in a lot more heat to overcome heatsinking.

Bar Stock, Copper Alloys - Spot Weld, Inc.

Copper and it’s alloys provide the greatest balance of conductivity and abrasion resistance, as it relates to resistance welding. It is for this reason that copper is so widely used on quality production resistance welding equipment. As such, Spot Weld, Inc. has a unique understanding of them.

What electrode material should I use for resistance spot ...

Higher conductivity alloys, such as copper/zirconium and dispersion strengthened copper, show some benefits when welding coated steels as they provide less surface heating because of their low contact resistance. When welding harder sheet materials, such as stainless steels, much higher electrode forces are required but lower welding current.

Guide to Copper Welding - Weld Guru

Copper may be welded with a slightly oxidizing flame because the molten metal is protected by the oxide which is formed by the flame. If a flux is used to protect the molten metal, the flame should be neutral. Oxygen-free copper (deoxidized copper rod) should be used rather than oxygen-bearing copper for gas welded assemblies.
