Basics of Arc Welding

Tuesday, May 3rd, 2011

Welding is a very easy process to learn about. Arc welding and stick welding are one of the most basic and common welding techniques that are initially thought to every welding student. Arc welding can be thought in four basic steps.

Step1: Equip yourself with safety accessories before you enter the domain to weld. This is a must irrespective of what your experience in welding is. Even the most experienced, brilliant welder has to take care of safety precautions before he starts to weld.

Step2: Always work with clean metals. This is a preparatory stage of welding. Clean your work piece properly before you work upon it.

Step3: Check for the welding earth connection. Make sure it is good. You are mainly using electricity to carry out the task of welding and if your earth connection is not good enough, you are most likely to mess up the task. An area of potential problems can be eliminated

Step4: Strike the arc properly. This is one of the biggest concerns for any welder and there are only three possible ways to do it;

•    Flick up from an edge
•    Strike like a match/scratch it
•    Tap it straight down, then back up

Hold the rod as straight as possible.

Differentiation of Consumable and non consumable electrodes

Tuesday, April 12th, 2011

There are two types of electrodes that are used normally during a welding process. This can be a consumable electrode of a non consumable electrode.

Consumable electrodes are the ones that would have significant changes in their structure when they are used. This is to say that these electrodes would be consumed in their use. Non consumable electrodes are the ones that are not consumed during the process of welding.

Some welding processes require a flux coated electrode. These electrodes when used would create a smoke around the weld. This would help to stop the air around the weld. Also a consumable electrode can melt and mix with the weld creating a stronger bond.

Therefore the choice between using a consumable and a non consumable electrode lies between the types of metal that is set up for welding. A consumable electrode can aid in the process of better elimination of impurities.

Portable welding machine – A real boon

Tuesday, January 18th, 2011

Welding as you all know is a very important and one of the most crucial part in a manufacturing unit, it is considered as the significant process. You need a lot of expertise to finish this task, welding is not an easy job, where you just have to weld two metals together; it needs a lot of practice and experience to do it perfectly.

Today, everything comes handy, so are welding machines, welding operators need to move from one place to another for work, so the what’s apt for their kind a job is a portable welding machine. Portable welding machines are really advantageous in plants, because you won’t know where the equipment will be needed from one hour to the next. So a portable machine like this is the right kind of equipment for this kind of job, where you can save time and increase the productivity at the same time.

Types of Automated Welding Process

Monday, December 27th, 2010

“Automated welding” as the name says is done automatically or by machine. This process is divided into two categories:

A) Fully automated welding process
B) Semi automated process

Both the processes are same up to certain extent as they have automatic mechanical component that allows them to fuse a piece of metal. These procedures are computer oriented that provide them their controls over operations, this mechanism usually called their controller units.

However, there are some differences between them such as; when it comes to fully automated welding process, it needs minimum human interface to perform its functions. On the other hand, if it is the semi automated welding process then it requires great amount of human involvement to get the welding job done with accuracy. Fully automated process can fuse at high speed that is not possible manually. These machines have the capacity to repeat the procedure at very fast velocity and their repeatability over & over again provides them supremacy.

Semi automated welding procedure is reliant on individual interface. This operation requires the operator to do quality inspections or check for error if any. This process must have a welder to carry out the task.

Usage Of Computers In Welding Industry

Friday, December 24th, 2010

Likewise in every skilled trade, in today’s fast changing world, the usage of computer is becoming more common in welding industry too. A few of its basic program structures offers a cross reference to welding filler metals, other programs support in selection of weld symbols.

Some of the multifaceted program structures permit welders to design structures and at the same time experiment them for its durability without ever constructing them. Such computer programs assist in generating proper and accurate designs and make more efficient usage of materials which further results in better and more lucrative construction.

Universally used programs are Arc Works is made use for documenting Welding Procedure Specifications (WPS), Procedure Qualification Records (PQR) and Welder Qualification Test Records (WQTR). These documents are broadly employed all over the welding industry.

In general most welding programs function in array of platforms, but the most accepted ones utilize the version of Microsoft windows. Those welders who understand the working of Windows will witness a good start with the programs and software’s that are designed for welding industry. Through this the job of weld becomes easier and they get an opportunity to work effectively.

Know about welding power supply:

Tuesday, November 30th, 2010

Power supply, it is essential for all machines, and in welding it is definitely needed because it provides electric current to perform welding. Welding is a process that requires high current around 80 amps. Constant current and constant voltage machines are the two classifications in welding machines and a constant current machine vary its voltage and the constant voltage machine vary its current of their outputs in order to maintain a steady current and voltage respectively. The modern welding machines use internal combustion engines to convert mechanical energy into electrical energy and you can build a switching power supply with the advent of inverters known as inverter welding units.

The infineon IGBT welding machines are more efficient and have better control than other types of non-inverter welding machines. And with these machines, the users can produce the desired voltage or current. This machine has power control features and overload protection features so that you need not worry about high voltage or current problems.

Plasma arc welding and its uses:

Thursday, August 5th, 2010

The history of welding dates back from World War II but plasma arc welding was discovered few years ago. Plasma arc welding is a process which is very similar to arc welding. Here an electrode is inserted through a nozzle which allows separation from the shielding gas. This results in high intensity of plasma stream which is ample for attaining high speed and temperature of the arc. The advantage of plasma welding is they can weld on thinner metals. Plasma welding machines can be operated either manually or automatically. These welding machines create very thin and straight welds.

The plasma arc welding is considered to be one of the economical and efficient welding methods. These are known as the most consistent welds in today’s world. This welding machine needs less stress for applying to the welded pieces. These produces high heat of electricity which cuts a very rapid line on the metal. These are capable of cutting metals with painted or rusted surface. These are capable of welding for many applicators where the regular method of welding failed.

How to resolve the Amperage when Welding

Tuesday, May 18th, 2010

Welding uses an electrical power basis to produce heat to melts the flux on an electrode. Amperage choice is a critical fraction of welding and may be predicted based on the electrode size and composition of the metal you will be welding, among other thing. The following steps will demonstrate how to resolve the amperage when welding.

Assess the affiliation between electrode size and metal thickness. A thicker base metal will require more saturation for an effectual weld and a thicker electrode.

Set the amperage to the optional setting for your exact application. Mainly new welding machines have a plan permanently attached to them which shows the amperage settings for common grouping of electrodes and base metal thicknesses.

Approximate the first amperage range upon electrode size. When the electrode has been selected; the accurate amperage might be possible at one amp per thousandth of an inch of the electrode’s diameter. Consequently, an electrode ¼ inch wide would need 250 amps.

Make use of one pass for a slender base metal. The standard welder at residence must have a welding apparatus in the regular 225 to 300 amp series that will permit metal of up to ¼ inch thickness to be welded in a single exceed.

Make multiple passes for a broader base metal. In the practice session, even professionals use multiple passes for metal thicker than ¼ inch rather than using extra than 300 amps. This is mainly because a welding torch will be able to weld continuously below certain amperage but will need to cool off sometimes at higher amperage.

The Referral Lines In Welding Symbols

Wednesday, March 31st, 2010

It’s true that it will seem all Greek and Latin while you first look at the Welding Symbols. You might no understand head or tail about those symbols but then these symbols are like a lantern in a dark way.

You may consider the Welding Symbols just like a new code language or shorthand that lets you know a lot of information on the weld that you cave to carry about and one you are exposed to these symbols and get used to them, welding will seem to be a much easier process than ever.

The first and foremost piece of weld symbols is a horizontal line and this is the one that lets you know about a lot of information and is called as the reference line. The main thing to note is that one can find that the types of weld are normally shown with a symbol to denote it. These symbols will be normally being near to the center where the reference line is there.
