Setting up welding equipment:

Monday, October 4th, 2010

Before setting up your welding equipment understand the functioning of each component for safety purpose and allows you to produce a better product.

• Check all the cables and replace them if necessary before starting a new welding project.

• Plug your power source, to find out which type of welder you are using, into the appropriate electrical outlet. Arc welding power source provides either an alternating current (AC) or a direct current (DC) using either positive or negative electrode.

• Connect electrode lead from welder to the insulated electrode holder.

• Place proper electrode in the electrode clamp.

• You can complete the circuit from work lead to base metal with the help of a welder.

How to choose an Arc Welder:

Thursday, September 23rd, 2010

For arc welding, a welder should choose the right welding equipments. Choose one based on your needs, has right features and comes in your budget. If you choose right arc welding equipment you can complete all your jobs properly and on time. Below are certain points that can help you in buying the right equipment.

• For outdoor projects, buy flux core type of welding equipment. It’s portable and protects cooling metal even in stronger winds.

• Use gas metal welder for indoor work. It produces less splatter.

• When you’re buying a arc welder, make sure it has a seal of approval either from National Electric Manufacturers association or underwriters laboratory.

Design Features:

• It is important to find out the thickness of metal before welding. A 90 amp welder can weld a metal which has 2.0mm thickness. For a very thin metal, a 25 amp welder would be best.

• Always buy a welding equipment that has correct amperage for the metal.

• Always select a welder that has trigger.

How a welder can weld steel:

Monday, August 16th, 2010

Steel is made up of iron. There are various elements that affect the steel’s physical properties. The more carbon it has, it becomes harder and stronger. Welding is nothing but combining two or more matters, commonly steel. These are some of the steps in using the stick process on welding steel.

Start by getting the necessary materials for stick process. These include electrode holder with lead, electrodes, metal which will be required to be welded, ground clamp and a welding machine. You may also require a wire bush for cleaning the welds and a chipping hammer for getting rid of the slag.  Always wear safety equipments like safety glasses, work boots, gloves, welding jacket, welding helmet and pants without cuffs. Find the perfect welding spot. Make sure you put away all the flammable substances and search for a good surface for welding. Prepare the machine and set it up. The most commonly used amperage is around 90 to 120.

Importance of welding gear:

Friday, August 6th, 2010

The welder requires welding gear besides welding torch and equipments for fabricating metals. You will find variety of safety equipment which is used while welding. Some of the welding equipments are welding gloves, welding helmet, welding mask and welder helmet. Welding gloves are worn for protecting your hand from sparks and flames produced during the welding metal. These are flexible in wearing and removing at the time of welding.

There are certain elements which can cause destruction during welding metals. So you need to take proper care and precaution like welding helmet is used while welding. Welding is an important part in fabricating industry. If proper care is taken while welding then you can damage your eye. There are many reasons like the ultra violet rays and infra red rays which emits from welding can damage your eyes. Some metals contain lead and chromium which emits poisonous gases into the air while welding. But you can protect yourself from inhaling these gases by wearing welding masks.

Know more about flux cored welding:

Tuesday, August 3rd, 2010

Another type of welding is the flux cored welding. This process is generally seen either in semi automatic or automatic welding. Here the welder has to continuously feed consumable electrode at constant voltage which should contain flux. You can also use shielding gas which will protect from contamination. Since this process is known of speed these are mainly used in construction. These are light weight and portable.

If you are using consumable electrode for filler metals then you can use these from any position. These can weld even in windy condition. These can weld on all kind of steel. There are two types of flux cored welding where one uses shielding gas and the other doesn’t use shielding gas. These are mainly for thin materials. You don’t have to clean the metal when welding is done with the flux cored weld. The welder here doesn’t need high skill for using this welding. These are also used by the farmers and home makers for welding small things.

Steps in setting up welding equipment

Thursday, July 29th, 2010

Learning to set up welding equipment properly is the first step in arc welding. For ensuring safety, it would be better if you understand your equipment as well as the functions very thoroughly. This would also help you to produce a better product. To begin with the set up, you need to check all cables for damage and replace if necessary before starting any new welding project. This is to make the welding devoid of nicks or frays in the welding as it may lead to pose an electrical hazard.

Depending upon the type of welder you are using, plug your power source into the appropriate electrical outlet. The power provided from the arc welding source would be either an alternating current (AC) or a direct current (DC) using either a positive or negative electrode. The factor that determines the type of job would be the current and polarity that you choose.

The third step is to connect the electrode lead from the welder to the insulated electrode holder. Once you have connected the electrode, you need to place the proper electrode in the electrode clamp. As you guide it along the weld joint, an electrical arc would be formed between the base metal and the electrode. For completing the circuit, you have to run the work lead from the welder to the base metal. This can be done by attaching the ground clamp to the piece of metal you are working on as close to the weld as possible.

Short note on spot welding:

Wednesday, July 21st, 2010

There are many kinds of welding such as Mig welder, Tig welder, Arc welder and many others. You can also find few resistances welding such as spot welding. Spot welding is mostly used for welding sheet metal fabricators. It is a process of touching the surface of metals by heat which is joined with another metal where the heat is generated from electric flow to resistance.

These welding are one of the oldest and were known as projection welding. These are very useful while welding for thin foils. These are energy efficient and also can weld in high speed. This welding equipment has an ease of automation and are very easy to handle. These are used for many kinds of applicators such as automobile industry, orthodontist and many other industries. You can spot weld the aluminum alloy with the use of powerful welding transformer. This is very useful for welding the sheet metal for cars and can weld automatic with the help of robot. These are also utilized for joining the cells of batteries with nickel straps. The battery might get hot while soldering but nothing will happen if you use spot welding.
