Welding is a sculptural process where it deals with raw items such as metal and pipes and it is a process where welders deal with welding fumes and heat. From the decade, welding has developed a lot and new welding technologies with advanced welding equipment and welding systems have been developed. When you consider the history, there were no welding schools at that time, but today you can see lots of welding schools and modern welding products with advanced welding tools have been introduced. Manufacturing process needs welding and it fails if the welding industry is not developed and equipped well with proper welding products. For the welding industry to run successfully the industrialist needs proper welding accessories with appropriate welding safety and welding gears. Plasma cutter has made the strong foundation in welding industry and plasma cutter machine is also used for the process of plasma gouging process. It is a process that is used to remove the welded materials and also it find cracks, porosities in welding materials.

Brief insight into hot air welder
Tuesday, August 24th, 2010Hot air welder otherwise known as the hot gas welder is a kind of plastic welding technique which is almost similar to gas welding metals. However the specific technique is different in both the welding method. A hot air welder, which is a specially designed heat gun, produces a jet of hot air that softens both the parts to be joined and a plastic filler rod. It is important to note that all of the things to be welded must be of the same or a very similar plastic. However welding PVC to acrylic is an exception to this rule. For manufacturing smaller items like chemical tanks, water tanks, heat exchangers and plumbing fittings, the hot air welder is the most common fabrication technique being used.
If the welder is used to weld case of webs and films, a filler rod may not be used. Here two sheets of plastic would be heated using a hot gas or a heating element and then rolled together. This process is comparatively fast and can be accomplished continuously. There is another variation in the hot sir welding technique. It is called the freehand welding in which the jet of hot air from the welder is played on the weld area and the tip of the weld rod simultaneously. The rod is pushed into the joint and fuses to the parts as it softens. This process is slower compared to others. But the welding is versatile and can be used in almost any situation.
Uses of commercial welders in the industry
Friday, April 23rd, 2010Does the term commercial welder sound new to you? Though the term is not popular, you all must know what commercial welders are. They can be electric welders, spot welders, gas welders as well as MIG or TIG welders. The commercial welders are of great use in the industrial sector for completing required weld on various jobs. The finished weld that comes after the welding process strengthens the products produced in the industrial sectors.
Commercial welders have increased the productivity in many companies. The welding processes have found to be cost effective in large terms and also the final outcome is of high quality. The welders are also capable of handling extreme production expectations. The portable welders make it possible for the companies to weld out in the outdoors or away from the industrial outlets.
Yet another interesting feature of the MIG, TIG or spot welders is their capacity to operate in various electrical sources. The commercial welders are in three phase option where as their counterparts i.e. residential welders are in one phase option. Due to the three phase option, the welding is completed in a quicker time. This would be a relief for the industries that are based on field fabricating or repairing various equipments.
Things to Do for a Perfect TIG Welding
Monday, April 12th, 2010The three things that you have to look out for that perfect TIG Welding is the length of the arc, torch angle and not shielding the hot tip of the wire.
What happens when an arc length is too long is it won’t pinpoint the heat. If you have long arc, then your TIG welding will turn to be gas welding. If you find that the tip of the rod is blobbing into the puddle, then you can identify that you arc is too long.
Same ways, too much of torch angle will even make the rod to blob. Positioning the thing that you are welding or yourself so that the torch angle is reduces and still making sure that you are able to see the tip of the electrode, is the right way to do it.
If you fail to shield the hot tip of the wire then things won’t come out well as you planned for. When you shield the tip then you can see that the puddle flows out as smooth as honey and your TIG welding will be as neat and tidy as you wanted it to be.
TIG Finger for an Easy TIG Welding
Tuesday, March 30th, 2010Just like any other welding techniques TIG welding is equally complex but can be made easier with simple tips those are easy to follow as well. It’s advisable to always use a TIG Finger heat shield during the time when you carry on your welding process. Other than this you may not be able to find a better way to steady your hands.
In fact this is one of the trusted and proven to be an easy way for great TIG Welding results. Many try using a TIG Finger made out of a finger from an old leather glove or any other leather bit. But it might not prove to be as efficient and safer that a high-tech TIG Finger that is heat resistant and can slide easily on hot metal pieces.
While you work on aluminum casting objects like transmission housings which want to be preheated or if it gets too much heated up while welding then a TIG finger will surely be of a great help.
So, here you have got an interesting and useful tip for the day to make your welding experience even happier and easier in the coming days.
Tips For Buying a TIG Welder
Tuesday, November 10th, 2009Advantages of TIG welding have no end. Yet, there are times that TIG cannot be a suitable choice to weld. TIG or GTAW is expanded as Tungsten Inert gas and Gas Tungsten Arc Welding respectively. Here are some factors that should help you to decide on using a TIG welder.
Work – Depending upon the type of welding task that has to be completed decide upon the welder type. Look for efficiency, metal type and speed to come to a conclusion. TIG welders provide great quality welds.
Quality – Quality is another aspect in welding. Choose a welder that will be apt for your quality needs. TIG offers great quality. It is prevalently used in nuclear work. This should explain the quality of welds it is capable of offering.
Metal thickness – If the metal that is to be welded is of less than 1 inch thickness then you should go in for MIG or stick welders. They are great for welding metals will smaller thickness.
Various Types of TIG Welds
Tuesday, October 13th, 2009TIG Welder can be used to make a variety of welds. And you can be a master if you learn the tricks. Some weld types that can be obtained with a TIG welder are listed below:
- Fillet – When 2 metals are fused at right angles then this type of weld is born. This is an easy weld.
- Lap – If 2 metals are made to rest flat against each other then it is lap weld.
- Butt – This weld is difficult to perform. It is 2 metals made to touch along the edges. Dealing with corner requires great practice and precision.
- Cosmetic – When longer welds are performed this weld type can be chosen. Make use of this weld type on highly visible joints. A very good example would e bicycles.
- Strength – These are stronger welds. They are primarily for durability and potency.
Only practice, innovativeness and precision can make you a great TIG welder.
Welding As A Career
Friday, July 17th, 2009Demand for professional welding has increased in certain industries like aerospace, automobile manufacturing, pipefitting, power plants etc. Since 1994, there has been an increase in welding jobs. Most of the welders work in manufacturing, construction, or wholesale trade sector. Most of the welding jobs are done manually, but some require machinery. Welding equipments like arc, gas and flame torches can be used to perform various welding tasks. Welding can be done for any position such as flat, vertical etc.
If a person wants to become a welder, he should have good eyesight, manual dexterity, good hand-eye coordination, should be able to bend, stoop and work in awkward positions. Have the Ability to work for longer period of time and undergo training so that he /she can perform the task in a better way. If a person wants to become a welder, he should have passed high school or GED (General Education Development) and complete a formal training program. There are various training schools and institutions for welders. Various subjects in welding training include, blueprint reading, shop mathematics, mechanical drawing, physics, chemistry, metallurgy and computers. Welders should have basic knowledge in mechanics, production and processing, building and construction and also engineering and technology.

How to Tig Weld?
Monday, June 29th, 2009Gas tungsten arc welding (GTAW) also known as tungsten inert gas
(TIG) welding, is an arc welding process that uses a non consumable tungsten electrode to produce the weld. The welded area is protected from getting contaminated with the help of shielding gas and a filler metal such as aluminum or stainless steel. Gas tungsten arc welding can weld stainless steel and light nonferrous materials like aluminum and magnesium. Tungsten inert gas does stronger and higher quality welds when compared to its competing procedures like shielded metal arc and gas metal arc welding. Tig welding is complicated, difficult and much slower than other welding procedures like mig or arc welding.
Manual tig welding is considered most difficult among all the welding procedures in the industry. Because welding operator has to maintain a short arc length, make sure that great care and skill are required to prevent contact between the electrode and the work piece. TIG Welding generally requires two hands because the welder manually feeds a filler metal into the weld area with one hand while manipulating the welding torch in the other.
In the beginning, tig welding may be considered complex and difficult task but through regular practice and tuition it becomes easy for the welding operator to perform the task. In tig welding, very less cleaning is required, the finished weld is neat & tidy allowing an artistic feel to the work. Major examples of quality tig welds are bicycle frames, marine fittings, interior kitchen fittings and steel artwork.
