Welding is the concept wherein two or more metal work pieces are joined together with the help of a molten solution fed by the welding gun that forms the bond between the work pieces upon cooling. This technique is severally used in heavy industry manufacturing where lots of metal raw materials are used for manufacturing things. Sheet metal is one among the complicated things that might require welding either during manufacturing or servicing.

Welding is an art where two or more work pieces are joined together with the help of a molten solution that forms the bond between the work pieces. The process of welding is predominantly used across many heavy manufacturing industries that deal with the production of steel and other kind of metal products.

Welding has certainly revolutionized the art of heavy industry manufacturing and enabled us to give rise to some of the most comprehensive and sturdy steel and other metal products that we use on a daily basis.

One of the biggest joys and frustrations in TIG welding is welding stainless steel. It can go great or it can go awful. Welds can look smooth as silk or look like burnt sugar. But one of the things that can help ease the process some is having the right filler rod to start with.

If you have got room for it in your budget, and want to complete your line of "necessary" welding rods you're going to need for welding most grades of Aluminum, the ER 5356 is right next to the ER 4043. Most TIG welders find the 5356 relatively easy to lay a nice bead. Comparatively, the strength of the 5356 is fairly high. Comparatively, the strength of the 5356 is fairly high.

So you want to TIG weld aluminum but don't know where to start or what classification metal you are dealing with?

If you are looking for a disappointing first welding experience, buy the ER70S-3 for filler metal. The ER70S-3 wire is often referred to as having a "moderate" deoxidizer content. In reality by comparison, this is really little or none. The question of course comes immediately to mind, “Why use it?” The answer is that it is really economical to use, especially if you have exceptionally clean metal. ER70S-3 is among the cheapest wires to buy.

A good choice for almost any mild steel TIG application is the ER 70S-6 filler rod. It's reputation is well deserved thanks to the high deoxidizer content of the filler metal. The overall melting and wetting characteristics are unparalleled, especially on less than ideal metal, where rust or other contamination may be a concern. The first thing you'll notice is how easily the metal “wicks” to the sides of the puddle and joins itself to the parent metal.

Ever want to build a race car or a roll cage? If so, become familiar with the ER 70S-2 steel filler rod. The 70S-2 enjoys a reputation for being a good rod to use for high strength 4130 chrome moly steel. It is the primary structural component of nearly every motorsport vehicle custom built, from motorcycles to Baja race vehicles. The strength and ductility of the 70S-2 makes it a favorite choice for people in the fabrication and racing industry. The 70S-2 is a practical all around rod however and works well with less critical welds as well.

When welding stainless steel one of the finest rods to use is the AWS E 309L. The 309 is a versatile welding rod. Its capacity to join stainless to stainless, stainless to steel, or steel to steel makes the 309L a favorite rod the job site. The corrosion and wear resistance of the 309L is quite high. It’s often used in the pipe industry to join fittings and valves where corrosive or abrasive material might cause fast wear and damage to the joint. The 309L has considerable slag so it’s a little difficult to use.
