Tig Welding Rod Types

Types of tungsten electrodes.

Tig welding rod types.

The following tig mig classifications for wire and rod can be used on sheet metal high pressure pipe and tubing. Within both of these groups there are many different variations and types which will be covered in more detail later. Er308 and er308l one of the most common welding rods it s the choice for welding 304 stainless steel which is widely used in manufacturing as well as 200 series and other 300 series steels. For tig welding the welding rods do not melt so are called non consumable electrodes.

Each of our rods have a smooth arc thin and uniform coating and low spatter. In contrast with many other types of welding the aws american welding society does not provide any specifications for carbon electrodes but the military has given a list of guidelines for optimum sizes based on the job requirements. Secondly tungsten electrodes are the type of non consumable electrode used in tig welding. 0 4535kg non permeable plastic tubes with rubber end caps to keep your rod clean and dry.

Er308l stainless tig rod when you know that you are welding 300 series stainless steel 304 is the most common 300 series stainless used you cant go wrong with er308l rods. The thickness of the material you will be welding also determines the required diameter of the filler rod. In tig welding you feed the filler rod into the molten puddle by hand. Keep on reading to find out what tungsten to use for tig welding.

Choosing the right electrode is a critical part of an efficient welding procedure. Your choice of filler rod is extremely important as the rod must correctly match the alloy of the material you will be welding. For your convenience we offer 36 91 44cm long rod conveniently packaged in 1lb. We understand that you don t always need 10 pounds of tig rod when welding small or one off jobs.

Welding rods are usually coated although the materials that make up this coating can vary widely. Use our tig welding rods with all types of steel and chromyl tubing. When the welding rod connecting the two materials together fuses permanently with the metals it becomes a consumable electrode in other types of welding processes such as tig welding the welding rods don t melt. Gas tungsten arc welding gtaw also known as tungsten inert gas tig welding is an arc welding process that uses a non consumable tungsten electrode to produce the weld the weld area and electrode is protected from oxidation or other atmospheric contamination by an inert shielding gas argon or helium and a filler metal is normally used though some welds known as autogenous welds or.

The type and size of the electrode vary with the kind of metal and the joint. There are a lot of other stainless steel filler rods like 316l 321 and others and if you know what you are welding its best to use a match.
