In the submerged arc welding process, mostly solid wire is used, it also depends upon the base metals and desired requirements. However hard surfacing composite wire also being used along with the Flux.
Tungsten Inert Gas (TIG) welding or Gas Tungsten Arc welding (GTAW) is a process by which the metal joins by heating them with an arc between a tungsten electrode and the parent metals.
Stainless steel being welded with the help of TIG Welding Machine (DC) power source, TIG Torch, Argon gas, and SS consumables (WIRE).
SPOT Welding/ERW uses non-consumable electrodes/wire.
Welding machines step down the voltage and increase the current (Amp) and while welding heat being generated due to high current which helps to get the molten stage of two mats which are being welded along with the extra fused mats like electrodes etc.
Metal Inert gas (MIG) is an arc welding process that uses a continuous solid wire heated and fed into the weld pool with the help of a welding torch.
Spot welding (also known as resistance spot welding) is a resistance welding process. This welding process is used primarily for welding two or more metal sheets together by applying pressure and heat from an electric current to the weld area.
A butt weld is one of the simplest and versatile types of weld joint designs. The joint is formed simply by placing two pieces of metal end-to-end and then welding along the joint. Thin sheets are usually welded without any weld edge preparation.
In an upset butt welding, there are jaws made of copper, into which the part to be welded is put and hence a solid contact is made. At this point of contact, while the current flows it gets transformed into heat because of electric resistance.
Aluminum is difficult to weld because it is a soft, highly sensitive metal insulated by a tougher oxidized layer. Aluminum is highly susceptible to impurities in its molten state, Mostly TIG Welding with AC preferred for welding.
The most common defects are Porosity, Undercut, Incomplete fusion, Incomplete penetration, Slag Inclusion and Spatter.
It depends upon the input power required by the machine and running with load etc. To calculate the power consumption of the welding machine, we need to multiply the wattage of the welding machine by the operational hours.
For nonmachinable Cast Iron welding-Low hydrogen (Without Iron powder) type electrodes being used and for Machinable welding Pure nickel, cupro-nickel, and Ferro-nickel type electrodes used as per the requirement.
To weld dissimilar metals, it is mostly preferred high alloy SS electrode with around Cr-30% and Ni-10%.
MS strip is being rolled during the manufacturing process to get a round shape and at the same time flux being filled inside the Core, hence the Flux Cored wire is built.
High-alloy steels are defined by a high percentage of alloying elements. The most common high-alloy steel is stainless steel is which contains at least 12 percent of chromium.
As indicated in shielded metal arc welding, the coating is being provided to give shielding to molten weld metal during the solidification as a SLAG and provide the gas shielding during welding and add other alloying elements.
No, it is not necessary to apply pressure on the Submerged arc welding process.
Yes, we have plenty of blogs available on our website’s Blog page, here you can read as well as subscribe for future blog updates.
Mostly the similar type of Stainless Steel electrodes are being used for the welding, for example, SS-308/316 Grade.
Both of the processes having their own advantages/disadvantage, usually, MIG welding is used for heavy and more productivity and TIG welding being used for ROOT RUN welding.

Together with carbon, manganese is responsible for the hardness and strength of steel. Besides this, manganese significantly improves the plasticity of steel and its toughness. It also works as a deoxidizer.
Sections of hardened steel plates of various thicknesses (as per requirement) which are welded (or bolted) in areas of severe wear, such as the insides of feeders, crushers, transfer chutes, or any other area where mined material passes, creating abrasion, and threatens to wear of these areas to enhance service life
The coating is being provided to give shielding to the molten weld metal during the solidification as a SLAG.
There are typically three types of welding machines: 1.Welding Transformer 2.Welding Generator 3.DC Welding Machine ( Maybe Inverter or Thyrester type).
It's a power source that helps to get ARC welding.
Inverter welding machine helps in providing the direct current mostly used for special welding.
TIG (tungsten inert gas) welding machine consists of a TIG torch and provides the DC and shielding gas through the machine.
D&H Secheron works with many different industries and provides its services, you can check our Industry page where you can find specific products related to the specific industry.
SMAW is a manual arc welding process in which electrodes are used to join two metals whereas in the GTAW process-Tungsten is used to generate arc and another filler wire being fed for the joining of two metals.
Shielded metal arc welding (SMAW) is a welding technique that can be used on all welding positions. A flux-coated electrode (which is a metal stick in an electrode holder) is connected to a power source and touches the base metal to produce the weld.
SMAW is often used to weld carbon steel, low & high alloy steel, stainless steel, cast iron, and ductile iron and Nickle.
In TIG welding, a tungsten electrode heats the metal which is being welded and gas (most commonly Argon) protects the weld puddle from airborne contaminants. TIG welding produces clean, precise welds on any metal
DC welding machine means which provide the DC ( Electrode +VE or -VE) as an out put for the welding.
Stainless steel wire is used in the GMAW process, also known as to MIG (Metal Inert Gas) process, in which the welding heat is produced by an arc struck between a continuously fed metal wire electrode and the workpiece
E-6013 welding rod is widely used for the welding of MS/CS in all positions as a very popular and easy welding process.
It depends upon the base metal, desired properties require, thickness, position and service conditions.
It totally depends upon the chemistry of base metal, service conditions, require properties, etc, however, most of the time E-7018 is preferred.
E-6013 welding rod is widely used for the welding of MS/CS in all positions as a very popular and easy welding process.
The difference between E-308 & 309 is E-308 is a SS grade and E-309 grade electrode being used to weld SS-308 to MS/carbon steel welding.
D&H Secheron is having a legacy of many famous products, However Norma, Medio, Supratherme, Sup(Spl), Cromotherme-1/2, Rutox-A/B/D, D&H-1212(NS), NFM, etc.
Spot welding (also known as resistance spot welding) is a resistance welding process. This welding process is used primarily for welding two or more metal sheets together by applying pressure and heat from an electric current to the weld area.
Copper wires and aluminum wires cannot be connected because the potentials of the two are different.
In upset butt welding, the jaws are made of copper, into which the part is welded is kept and hence a solid contact is made. At this point of contact, while the current flows it gets transformed into heat because of electric resistance.
Flash (butt) welding is an electrical resistance welding process used for joining components, where the energy transfer is provided primarily by the resistance heat from the parts themselves.
Pure argon gas can be used for both GMAW and GTAW welding.
Argon gas is used as a "shield" for the weld to cure without any flux whereas arc welding has flux that protects the weld bead.
Argon is a welding shielding gas that enhances arc stability and prevents atmospheric contamination of welding pools. Argon is essential to gas tungsten arc welding (GTAW). We can get the same from the Industrial Gas supplier.
X-ray welding is one of the latest advances in welding technology. Just like laser beam welding and electron beam welding, in this type of welding, the thermal heat that is required for the weld is produced with the use of a focused high-powered X-ray beam. This high-powered beam will initiate a localized melting of the metal that will form the weld once it is cooled down.
Oxy-acetylene torches can be used to weld aluminum.
No, we cannot use aluminum welding rods on steel.
TIG welding aluminum requires a shielding gas (usually argon), a tungsten non-consumable electrode, and a clean surface to remove any oxide buildup. The oxide has a higher melting point than the aluminum itself, which is why it needs to be removed before welding.
Yes, it is difficult to weld aluminum because it is an alloy.
MIG Welding with pure Argon gas is possible with lots of modifications like plastic or Teflon liner in torch with skill.
Electric welding is the joining of metal using an electrical arc and a filler metal stick electrode or wire. Welding is done by creating an arc between the base metal (the metal being welded) and the filler metal. The arc melts the base metal and filler metal, combining them into one material to join the base metals.
There are lots of common electrodes being used for both the Industry like Mild Steel, Stainless Steel, Hardfacing, Cast Iron, Dissimilar Electrodes, etc depend upon the application.
The passive layer forms because of the chromium added to stainless steel and due to which Stainless steel becomes corrosion resistant.
No, the low carbon steel is not corrosion-resistant.
An electrode is a metal wire that is coated. SMAW or stick electrodes are consumable, meaning they become part of the weld, while TIG electrodes are non-consumable as they do not melt and become part of the weld
A welding wire is a slim metallic rod that is ignited to generate a heated arc for the purpose of fusing metal pieces together (welding) by rendering the wire soft under an applied heat source.
Mainly name as a metal-cored wire which is a tubular wire filled with metallic powders, alloys, arc stabilizers, each of which offers distinct benefits such as lowering oxidation, providing higher impact strengths, and reducing silicon deposits in the final weld.
By way of lots of welding defects like undercut, incomplete fusion, slag inclusion, porosity, etc and accordingly have to do the rework which unnecessarily creates the production loss and will increase the other cost.

Shielding gases or welding gases can be purchased from the welding consumable dealing shop. Generally, these dealers keep the shielding gases along with them and sometimes provide the option of regional deliveries.
To choose the right welding rod one should have proper knowledge about the base metal & the application.
There are several educational bodies for students to learn about welding and become a certified welder. A student should enroll themselves in a registered institute where he/she can get complete knowledge about the welding process.
All welding processes are effective, however, it depends upon the job design, service conditions along with the desired requirements, and accordingly, a qualified welder can help in achieving sound weld.
Stainless steel retains heat very efficiently, which makes welding it a bit more difficult especially for a new welder. While welding stainless steel a welder needs to keep in mind that while applying excessive heat on stainless steel can result in warping and even distort during the cooling process.
Welders are responsible for checking the equipment every single time before performing the welding activity. A welder needs to check the cable, electrode holder, and coupling devices. All external connections should be clean, tight, and checked each time a reconnection is made.
Welding is an extremely technical and labor-intensive field that requires regular practice and precision. It is recommended that a welder should take proper education in a welding school where all the safety & precautionary measures are taken as welders operate large machinery and work with delicate materials using high heat.
There are many welding rods manufactured by D&H Secheron Electrodes Pvt. Ltd., especially for cast iron, such as NFM, D&H Monel, Fenitherme, etc. A welder should check on which application he needs to weld before welding.
Welding supplies generally consists of welding rod, welding wire, holder, welding machines, shielding gas,etc in the 21st century, we can buy welding supplies through online & offline mediums. To purchase through offline mediums a welder can purchase it from a local welding consumable store.
