They have filler material, which melts to create weld joints. The Voltage controls the weld profile. In most cases the gas used is always 100% Argon and in rare cases a helium/Argon mix may be used on base metals thicker than ½ of a inch. In this type of welding, you join two metals together using an arc. Almost any material can be welded using common welding processes: metal inert gas or metal active gas (MIG/MAG), tungsten inert gas (TIG) or electrode (manual metal arc) welding … Since you don’t have to replace your electrode as often, you can lay down bead after bead without having to worry. GMAW requires a shielding gas, to protect the weld pool from atmospheric contamination. Weldcote Metals - 6011 Mild Steel Electrodes. Ensure with multi-pass welds you use inter-pass temp control. Please Log in - Registration is … 'Recovery' is the weight of weld metal deposited in the weld relative to the weight of the core wire. The gas used most of the time is the same C2 or 2% carbon dioxide and 98% Argon. Stainless Steel Grades: 309 Stainless and Welding Carbon Steel to Stainless Steel or Low Alloy Steels. Aluminum Grades: 2014, 3003, 3004, 4043, 5052, 6061, 6062 and 6063. As for gasses the C2 (2% carbon dioxide and 98% Argon) is the most widely used. Several manufactures have developed electrodes specifically for welding weathering steel. Very useful information, thank you for this! Most Commonly Used Stainless Steel MIG Welding Electrode and Gas Mix Stainless Steel MIG weld done with ER308L Weld Wire and C2 gas. As for gas choices it is always 100% Argon gas. In MIG and GMAW welding, a continuous solid wire electrode travels through the welding gun, along with a shielding gas to shield the process from contaminants in the air, and into the weld pool. These stainless electrodes are mostly used for lower grade stainless steels 301, 302, 304, 305, and 308. For example; 4 – Designates series of Aluminum of which the electrode is made from. i can do all the welding required mma gma, It is very useful for quality welding process. Click here for instructions on how to enable JavaScript in your browser. Popular Stick Electrodes. These types of welding electrodes are preferred to use in Metal Inert Gas (MIG) welding. This electric arc … It may also be used to weld cast aluminum grades 43, 214, 355 and 356. There are two typical choices and they are: Now there are other choices but is rare to need any other electrodes. Some are much thicker for heavy industrial applications. In particular the number 6 means that more deoxidizers have been added to the wire, which is helpful when welding on dirty or rusty steel. Following gases are used as shielding gas; (NOTE: Whenever Carbon dioxide is used as shielding gas in Gas Metal Arc Welding (GMAW). It welds aluminum grades 2014, 3003, 3004, 4043, 5052, 6061, 6062 and 6063. The term MAG (Metal Actve Gas) welding is used, because Carbon dioxide is an active gas. In order to post comments, please make sure JavaScript and Cookies are enabled, and reload the page. The two base materials are melted together … MIG Welding carbon steel or mild steels are typically welded with a ER70s-6" electrode using either 100% Carbon Dioxide gas or C25 gas that is 25% Carbon Dioxide and 75% Argon mixture. In either case, the GMAW process lends itself to weld a wide range of both solid carbon steel and tubular metal-cored electrodes. Here is the electrode designation: These stainless electrodes are mostly used for higher grade stainless steels mainly in the food industries and marine applications. Hence, whenever theses gases are used as shielding gas, the term MIG (Metal Inert Gas) welding is used.). Even though most of the welding machine manufacturers have included a table of materials and voltage settings in the machine, it is highly important for you to pick the right kind of gas and electrode wire to be used for MIG welding … Weldcote Metals - 6010 Mild Steel Electrodes. Right Kind of Gas and Filler Wire. Click here for instructions on how to enable JavaScript in your browser. Required fields are marked *. This process is a very smooth transfer of molten metal droplets from the end of the electrode to the molten pool. When MIG welding aluminum, the desired mode is spray transfer. MIG welding stainless steel has a variety of electrodes because it is used on a wide range of projects that require different types of stainless steel grades. Carbon dioxide can be used alone also and it is effective while welding thinner metals. It covers most electrodes that are commonly used in the field for: Typical MIG welding electrodes are a solid wire ranging from a thickness of .023 to .045. It also has a lower heat input, with the exception of MIG in the spray arc weld mode, for less distortion and burnthough in the finished weld. Currently you have JavaScript disabled. It may also be used to weld cast Aluminum grades 43, 214, 355 and 356. This welding … These gases are used alone or a combination of gases can also be used. Metal Inert Gas (MIG) welding is an arc welding process that uses a continuous solid wire electrode heated and fed into the weld pool from a welding gun. MIG Welding carbon steel or mild steels are typically welded with a ER70s-6" electrode using either 100% Carbon Dioxide gas or C25 gas that is 25% Carbon Dioxide and 75% Argon mixture. Your email address will not be published. As a rule of thumb in most cases it will be a ER308L electrode … This is a detailed page about MIG welding wire selection. I will explain the meaning of these symbols: FOR CARBON STEEL OR MILD STEEL (SUCH AS ER70S-6 OR ER70S-3), XX – Designates the minimum tensile strength of the deposited weld metal. Other advantages include high electrode … The downside of using this electrode to weld steel to stainless is that the weld appearance is rough. Welders who are using this … Stainless Steel Grades: 304,305, 308, 310, 312, 314, 316, 317, 321, 347 and 348. Welcome to Varun Electrodes. The smaller the electrode the less power you need from your machine to run. MIG welding is the most basic type of welding process, which is suitable for starters. An electrode or a welding rod is a wire which is made up of wire and is coated. Stainless Steel is typically welded with the electrode classes and they are: The 309 series has a multi use designation because it is used to weld stainless steel to mild or stainless to carbon or low alloy steels. It is also known as gas metal arc welding. The wire designation is as follows. Keep your … This table is just a guide and the ranges may vary depending upon the shielding gas and parent metal. The welding wire in MIG welding runs continuously with lesser downtime for electrodes replacement; MIG welding is excellent for tack and spot welds; Limitations of MIG Welding. Among all the other types of welding, the stick electrode welding … In fact, MIG … In this case it’s a 4000 series Aluminum, 043 – Reflects the amount of silicone added to the electrode. GMAW (MIG welding) electrodes are designated by some letters and numbers such as ER70S-6, ER90S-6 and E308L etc. Stainless Steel Grades: 301, 302, 304, 305, and 308. It is typically used in industrial applications and it does get some rust spots from time to time. The electrode is made up of materials which are similar to that of the metals chosen to be welded. Get information on Welding Technician programs by entering your zip code and request enrollment information. We are a professionally … Some of the commonly used stainless steel electrodes are ER308L and ER309L etc. It welds stainless steel grades 304 through 310 when needed or welds dissimilar metals together where needed.
