Yes, the designation "EW" in filler metal specifications indicates the type of filler metal used for Gas Tungsten Arc Welding (GTAW). Specifically, "E" denotes the electrode, while "W" signifies that the filler metal is specifically designed for welding applications. This designation helps welders select the appropriate filler material based on the base metals being joined and the desired properties of the weld.

What is a welding filler ER 90SB2?
ER 90SB2 is a type of welding filler metal used primarily for joining high-strength steels. The designation "ER" indicates that it is an electrode rod suitable for use in gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW). The "90" signifies its strength level, while "SB2" indicates specific chemical compositions and mechanical properties tailored for applications requiring high toughness and strength. This filler is commonly used in industries such as construction, manufacturing, and automotive, where strong and durable welds are essential.

What type of welding are used in Ship building?
Ships are built in segments or sections usually in a building for protection from the elements, rain, snow, heat etc. Automatic MIG (GMAW) is used as much as possible. Manual MIG and stick (SMAW) are then used in places or positions automatic machines cannot get to. These sections are transported to building ways where they are joined together to form the ships structure. Thick sections are sometimes welded with the submerged arc welding process. MIG welding is then used where ever possible and stick welding is used every where else. Smaller pipe systems and light gauge sheet metal structures are usually TIG (GTAW) welded. Large pipe sections are MIG welded on rollers. Some are stick welded when in place on the ship. Newer processes such as Laser Welding is making inroads in heavy fabrications.

What are F No. in Gtaw filler metals QW-404?
There are 5 variables for PQR which reflect the filler metal: QW-404.5 - F-No. All solid and and flux cored wire are assigned to F-No. 6. QW-404.6 - A -No. For the same base metal the common used wire (solid or flux cored) have the same A-No.
Why must the tip of a tungsten electrode be hot in GTAW?
The tip of the tungsten electrode has to be hot in GTAW because you are trying to weld two pieces of metal together, and that takes a lot of heat.
What is meant by a defect in the GTAW process?
GTAW is the Gas-Tungsten Arc Welding process A defect means something's wrong with the weld. There are hundreds of kinds, and every kind of defect has a different cause--and sometimes there are seven or eight causes for one defect.
What filler metal is used to weld monel 400 to Inconel?
MONEL alloy 400 is readily joined by conventional processes and procedures. Most of the conventional welding processes may be used to join MONEL alloy 400 to itself or dissimilar alloys. The choice of welding product is dependent upon the materials being joined and the environment to which they will be exposed. For shielded metal arc welding (SMAW), MONEL Welding Electrode 190 is used to deposit near-matching composition weldments. For some applications, Nickel Welding Electrode 141, INCO-WELD A Welding Electrode, or INCONEL Welding Electrode 112 may be preferred. Properties of weldments deposited with MONEL Welding Electrode 190 between two sections of MONEL alloy 400 plate and between sections of alloy 400 and carbon steel plate are shown in Tables 20 and 21. For gas tungsten arc welding (GTAW) and gas metal arc welding (GMAW), MONEL Filler Metal 60 is used to deposit near-matching composition weldments. For some applications, Nickel Filler Metal 61 or INCONEL Filler Metal 625 may be preferred. These same filler metals may be used for submerged arc welding (SAW). INCOFLUX 5 is used with MONEL Filler Metal 60. INCOFLUX 6 is used with Nickel Filler Metal 61. INCONEL Filler Metal 625 is used with INCOFLUX 7.
In which process is the electrode used in welding?
Manual Metal Arc Welding(MMAW) Also GTAW (TIG) and GMAW (MIG) The MIG wire carries electric current so it is considered the electrode. TIG the Tungsten is considered an electrode.

Why does the welder need to understand the composition of an alloy being welded?
Almost all metals are "Alloyed" including Gold and Silver. An Alloy is an Element added to another Element to change its characteristics. For example Chromium and Nickel are added to Steel to create Stainless Steel. If you didn't know these were in the metal you wouldn't know what filler material to use. Filler material includes Electrodes (SMAW) Rods (GTAW AND OAW) and Wire (SMAW). Even Carbon Steel is Alloyed (to increase its Tensile Strength for example). Sometimes as little as 1/10th of 1% of an alloy changes the base metal considerably and thereby the uses of that metal.
What is the principle of tig welding?
Tungsten Inert Gas (orTIG) welding is also referred to as GTAW (Gas Tungsten Arc Welding) and by the term Heliarc® which was the Linde Company's trade name for the TIG process when it was originally introduced.The welding arc is started with a sharply pointed tungsten electrode shielded by inert gas. A separate filler rod is fed manually into the weld puddle in much the same way as is done when gas welding.The process is well suited for aluminum.
What is a base metal in welding?
A base metal is also called the Parent metal. It is that metal in the welding practice that has been cut by the various forms of cutting, then prepared and is to be welded. Welding is performed to join one section of the base metal to another section of base metal by means of the various welding processes, e.g. SMAW(Shielded Metal Arc Welding) where welding welding rods are used, GTAW(Gas Tungsten Arc Welding) where Tig wire is used, FCAW(Flux Cored Arc Welding) etc. The welding rods, the TIG wires etc are called the filler metals, for they fill the weld gaps by depositing their molten-state weld metals.
