Welding Wire Types

When most people think of mig welding they think of hardwire a mild steel process in which er 70 wire is used to weld regular steel.

Welding wire types. When it comes to mig welding it uses a combination of heat and an electrode wire to create a molten pool to fuse two pieces of metal together. Welding is basically a process of joining two metal pieces there are various welding methods being adopted by professional and the most common types of welding are stick tig and mig welding. Metal cored wire can handle mill scale and surface contaminants better than gmaw wire because of its metallic components. In mig welding you can easily join a variety of.

Er an electrode or filler rod that is used in either a mig wire feed or tig welding. The type of wire you choose will be contingent upon the location of the jobsite thickness of the application proper shielding gas combination and the type of equipment available. With this type of welding the electrode is non consumable and made of tungsten. The gasless name doesn t mean that there is no gas used to protect your weld.

But which one is best for a particular application. 6 the amount of deoxidizing agent and cleansing agent on the electrode this is a copper coating on the electrode and there are different types too. What newbies may not know is that there are so many wire types available that can tackle vastly different projects. Mig welding is actually two different types of welding.

The first uses bare wire and the second flux core. Flux core mig welding can be used outdoors because it does not require a flow meter or gas. The table below is commonly found in consumeable spec. Mig wire electrode label meaning for a er70s 6 label.

These components help the metal cored electrode deoxidize the scale better than solid wire which is the reason this type of wire is a better choice if you don t want to blast material before welding. Tig welding also goes by the names of heliarc and gas tungsten arc welding gtaw. Bare wire mig welding can be used to join thin pieces of metal together. You should always clean the workpiece before welding to ensure optimum weld quality and prevent impurities from becoming trapped in the weld bead.

The first type of flux core welding wire you can buy. These wires are designed to meet minimum tensile strength requirements of 70 000 psi. Gasless flux core wire is the first main type of flux core welding wire. The most common sizes for welding sheet metal are 0 35 and 0 45.

It is also the best choice for avoiding silicon. Welding always needs protection from. 70 a minimum of 70 000 pounds of tensile strength per square inch of weld. The first is the wire diameter which is usually given in thousands of an inch.

It s called gasless because you won t need a separate cylinder of compressed gas to weld with it. The most common types of mig wire for welding mild steel are er70s 3 and er70s 6. Once a wire type is determined for your welding equipment two additional pieces of information are needed in order to purchase this consumeable. Mig welding is one of the easier types of welding for beginners to learn.
