Mobile welders should select the right place for their business!!

Monday, January 31st, 2011

Welding is a very complex and delicate task which can be done perfectly only by an expert or a professional. Welding is one of the important processes of any product manufacturing. People these days prefer everything to be handy and portable, and that’s why all latest invention like mobile phones, laptops, notepads etc are in boom. So people expect all things to be mobile, same goes to welding, since it’s one of the important method in any manufacturing, they are also expected to be handy.  Mobile welders are also equally good as non mobile welders. Mobile welders are otherwise known as portable welders or rig welders. In mobile welders, the equipment is placed or mounted on a vehicle which can be moved from place to place. It is a very convenient means of welding both for the welder and the customer. If you opt for the correct location for your mobile welding service, that is, places like ships, yards etc, you will really have a good amount of scope to earn.

General information about plasma cutting machine!!

Friday, January 28th, 2011

In laymen terms plasma cutting is nothing but a process which can cut electrically conductive metal by using high velocity of ionized gas which is delivered from a nozzle. Plasma cutting is very apt for cutting steel and non ferrous material; it is mostly used by almost all industries and also by amateurs who are just beginners in welding. Generally plasma cutting machines are rated according to their ability to cut and its amperage. One basic thing which you have to keep in mind when you are buying a plasma cutting machine is that, if you want to cut thicker metals go for higher amperage cutting machine and if it’s of less thickness you can opt for lower amperage plasma cutter. The lower amperage cutter can cut thicker metals but it’s just that it won’t cut perfectly. So cutting with the apt cutter will give you a perfect finish in the cut.

Tips for arc welding

Wednesday, January 26th, 2011

Introduction:

In industries the arc welding playing the vital roll and it is more helpful in welding industries. Arc welding is used to make the machines in good shape and it works for more years depend upon the usage of the machine. Arc welding is a metallurgical procedure for two metals fusing by intense heat at the moment of fusion of the two metals.

Tips for arc welding basics for beginners:

Safety measures for arc welding:

In the initial stage for starting the welding works the welder should strictly follow some rules and regulations.

1.    Eyes and skin should be fully covered because the UV light is discharging from electrodes while welding.

2.    During arc welding use helmets compulsorily. To prevent the risks. The risks like fire accidents and shocks so the welders have to strictly follow the rules and regulations.

3.     And keep one bucket full of sand, welding helmets and gloves to start welding process.

Rules for arc welding:

Keep the welding machine on and at the moment of welding the welding machine should touch the fusion of the electrical circuit is fulfilled and the electric arc is produced. There are two methods of electric arc is there they are tap starting and scratch starting.

Rules for organizing the joints:

In arc welding while welding the impurities and dirt will be removed and it will modify the transmission. And the welders have to create joints for each arc welding it is more important for arc welding. This is more useful way for avoid some cases like cold joints and it is more helpful in creating the fusion more powerful.

Technique used in Gas Metal Arc Welding:

Tuesday, January 25th, 2011

Gas Metal Arc Welding (GMAW) otherwise called the MIG welding is partly an automatic process where the welding arc is constantly fed with shielding gas and wire electrode. This makes the welding technique very easy and simple when compared to TIG welding where the welding torch and filler wire is held in both hands which making it a chaotic process. MIG welding is made easy with proper positioning of the welding gun by maintaining an appropriate stickout distance. Not to forget the gun’s orientation, it should be at an angle of 45 degrees and 90 degrees for a fillet welding and a flat surface welding respectively, with the travel angle being vertical. If this simple technique is followed actively we can get a good quality MIG welding done.

Factors to consider before purchasing the plasma cutting machine

Monday, January 24th, 2011

Plasma cutting is a technology that grew out of plasma welding in the 1960s. It is a dynamic way to cut sheet metal and plate in the 1980s itself. Plasma cutting is best known for the thickness of the material. The plasma is suitably hot to melt the metal being cut and moves sufficiently fast to blow molten metal away from the cut. The basic rules in selecting the best plasma cutting machine is:

Select the cutting capacity which goes with the material’s thickness you will be able to save up to 80 percent of your time.

Cut quality is important in the selection of a tool, because the cut has a final touch in your product, as well as it has its effect on the time taken in the process of production.

Reliability is the most important factor in selecting the best tool. The reliable plasma cutting is manufactured with lesser parts where they make use of software instead of hardware. Finally the reliability is completely tested by ISO.

Operation is the best process in the plasma cutting tool. When an experienced operator handles this type of job the job will be completed quickly as well as the finished product will look professional. In case if an un-experienced operator handles this type of job you can’t get the better output as like an experienced operator. The experience level is apart from using the plasma cutting tool. If the operator knows to handle the tool then they can get their work done quickly and with a best quality.

The most significant components and fittings of TIG welding

Friday, January 21st, 2011

Most of the TIG welding equipment consists of gas device with controller and many of the element present they are welding torch, power cable, tungsten, electrode, gas nozzle this are the different types of elements is present, and also welding power source, motionless gas cylinder this are the elements present in this process.

Most of the welding torch consists of cooled air or else water if the welding current is more than 150 amps the air or water gets cold.

The filler rod is mainly used for heavier welding metal and the metal must have similar chemical of metal piece. The filler rod comes in two ways they are either in straight fixed lengths or coils.

Importance of Welding Helmets and It’s Types

Thursday, January 20th, 2011

A person who is working in the field of welding or just examining the welding process needs to wear a welding helmet .The reason why welding helmets are essential is because of the bright light given off by welding. Without taking safety measures, this light can factually burn the insides of your eyes and cause temporary or permanent blindness. Part of the reason is that mainly in dark places, the eye cannot adjust to the change in brightness fast enough to prevent damage. A good welding helmet not only protects you from rapid sparks, but also shields you from the extremely brilliant welding arc.

Today welding helmets have changed significantly. While they look quite a bit unusual today than they did years ago, you can still find two main types of welding helmet:

  • Passive
  • Auto-dimming

Whenever you picture welding helmets, you’re almost certainly thinking about manual, or passive as it’s also known. The main advantage to these passive helmets is that they often cost less. More recently, auto-dimming welding helmets have become more popular. These helmets, like the conventional manual ones, are a part of metal and a piece of glass. The auto-dimming helmets come in two types, some use infrared viewers whilst others use electricity to dampen the glass. Both use electricity.

Inverter Welders to save power

Wednesday, January 19th, 2011

The Inverter Welders are used by many experienced welders for various reasons, the main reason being the amount of power they generate when plugged into a normal household current. This type of welders is also very portable to carry to all places. It can be carried with just one hand and allows you to move faster and get into smaller places where your normal welder would never easily get in.

One of the amazing facts about the inverter welders is the deal of flexibility to weld in places where you don’t even have 220v power. They are not vulnerable to low quality power so that you should be fine running them off any type of generator. There should also be a pre power check done when you dealing with a non operational inverter welder.

Inverter welders are the one which suits for all the mig welding work and are convenient and portable. They also have 12lb roll capacity with optional drive rolls. The disadvantages are that inverter welders use high tech electronic components which are used in conventional welder which increases the cost a bit more for the same power, and need to be treated more carefully as it will not be as strong as the other welders.
These welders are used in general repair, automotive, motor sports, agricultural and more. Therefore, inverter welders can save you a lot of money on power bills over time. However it is wise to keep both traditional welder and inverter welder as you might find situations to use both.
