SAW also referred as Submerged Arc Welding or Submerged Arc Welded Tubulars is a welding process wherein the metals are joined by generating heat with arcs or an arc between the work surface and the bare metal electrode. In all major welding process a shield is provided to protect the welding, same applies in SAW welding in which the shield is provided by a blanket of granular fusible material on the work. No pressure is used in this welding process and filler metal required for welding is obtained from the supplementary welding rod or the bare metal electrode. These welding rods or bare metal electrodes are termed as SAW wires. These wires are available in both copper coated and stainless steel format.
The submerged arc welding process equipment consists of the wire feeder which allows the welder to control and manage the flow of SAW wire during the welding process. Apart from this, SAW welding process equipment also includes a power source or a welding machine, the control system, the feeding mechanism and the flux hopper, the travel mechanism for automatic welding, a flux recovery system, the welding torch or the welding gun for atomizing the welding process as well as the cable assembly for semi-automatic welding process.
The submerged arc welding process is one of the most complex and difficult welding process. This is because the welding machine is always rated for a 100 percent duty cycle, since the SAW welding operations are always continuous and the time required for completing a welding may exceed over 10 minutes. As a result, the SAW wires are meant to be tougher in quality and are highly durable to survive in extreme climatic conditions. The welding machines for submerged arc welding process are available in different sizes ranging from 300 amperes to 1500 amperes. Similarly, the SAW wires are also available in different sizes, shapes and consumption to meet these varied SAW welding requirements.
Overall, there are several advantages of submerged arc welding process as compared to that of other welding processes. Some of the major advantages of SAW welding process are:
1. The quality of finished welding metal is highly durable and lasts longs.
2. Minimal maintenance cost after the weld.
3. Lasts long.
4. High quality and durable SAW wires are used for the process.
5. Smooth and uniform result for welding without any spatter.
6. Generates minimal smoke during welding.
7. The need for protective clothing is minimal as there is no arc flash in the welding process.
8. High utilization of electrode and SAW wire.
9. Minimal and almost no participation of manipulative skills, ensuring quality in welding.
10. Extremely high speed and deposition rate.
A professional stainless steel wire manufacturing company ensures to produce and deliver quality SAW wires that match various international quality standards and are able to meet some of the most complex SAW welding requirements.

TIG Welding Overhead -How to Tig Weld Overhead
Fits Tig
One of the welding processes that grants greater control over other welding process and allow for stronger and higher quality welds is called as tig welding and it is normally used to weld thin sections of stainless steel, aluminium and more metals in an easy way. There is always a myth surrounding this welding process and it is, this process in more complex to weld and difficult to master, but it is not true now. Yes, once upon a time, this fact was true, but now everything has been changed and in the market, you can find a welder that welds excellently and efficiently. That much development has been made in this process. In this article, let us see about the tig welder and all about it. Tig stands for tungsten inert gas welding and it uses the consumable electrode called tungsten electrode to produce the weld.
The tig welder is generally more advanced than mig welding and with sufficient practice and capability; anyone can become as the master of this welder and can do the welding process in an easy way. Most of the buyers who buy this welder appreciate this unit due to its portability and economy and it is designed to weld any type of steel or stainless material. This welding machine makes repair easy in the field and it fits neatly into about any settings. This welder is fully capable of handling business on its own since it has the unique amperage of combination and features. There are different types of tig welding machines available and they are power I-tig200, powertig 185 micro, powertig 200DX, powertig 225LX, powertig 250EX and powertig 315DX. All these types of welders are of inverter type and it is of Infineon IGBT inverter type.
All these types of tig welder have over current warning facility and has maximum input amps and running amps. These welding machines are stable and has smooth arc characteristic with good puddle wet in. It is portable and light weight and adjustable welding parameters for welding operation. It has good duty cycle and it can withstand for many hours and do not leave out any poisonous or polluted gases so these welders are also called as environment and user friendly welding machines. It has a pulse function that increases the weld quality and reduces the overall heat input. It is easy to connect and the accessories allow you to set up this machine quickly and easily. You can take it anywhere you go since it is compact and portable.
This welding machine is fully of digital type and has digital readout for accurate setting of amperage and control. It is suitable to use anywhere since it has been protected properly. You can use this tig welding machine in all types of applications and can achieve good and quality welding. If you buy this welding machine, it is sure that you can enjoy numerous benefits from this welding machine.
