Welding is an age-old process of joining metals. Welding supplies are necessary for better metal works.
The environment is a concern for all of us today. One way of saving the environment is limited use of wood in constructions, small and big. Many wood replacements were developed to imitate wood appearance. The use of metals is the more popular wood alternative.
Use of metals requires an age-old process. This is the fabrication process or the joining of materials. Welding does joining of materials, metals, or even thermoplastics. Causing coalescence joins metals. The process involves melting the pieces to be joined together and having molten filler in between to form a strong joint. Heat is used, or in combination with pressure, in producing a weld.
Welding utilizes a number of energy sources. These sources include gas flame, electric arc, laser, electron beam, friction, and ultrasound. Welding is considered as an industrial process. In spite of this thinking, welding can be done in an unlimited number of circumstances one imagines. Welding is possible in an open-air situation, underwater and yes, even in space.
Welding is dangerous, in all location where welding is possible to be done. Care must be observed when doing a welding work. Precautions should be taken into consideration to avoid unacceptable consequences such as burns, electric shock, eye damage, poisonous fumes, and overexposure to ultraviolet light.
For centuries, welding is done through the simplest process of forged welding. Heating the materials and pounding to connect metals. In this procedure, heat and pressure are used. Historic structures and art masterpieces were constructed and fabricated using this simple welding process.
Arc welding is the most popular welding process used in many work places. This is done by an electric arc between an electrode and the base materials. The metals are melted at the welding point. Electric arc is created and maintained by the use of an electric power supply. Use of an alternating or direct current and a consumable or a non-consumable electrode is possible in an electric arc welding. Shielding gas usually protect the welding area.
Arc welding requires an electrical power supply. Most commonly used are the constant current power supplies and the constant voltage power supplies. The length of the arc is directly related to the voltage while on the other hand, the amount of the heat input is related to the current. In manual arc welding, the constant current power supplies are used most often.
Power or energy supplies are the most important supplies needed in the welding processes. Another requirement in welding is a continued supply of electrodes or what is commonly referred to as welding rods. Replacement supplies for the various welding equipment and tools might be an option for a continued and uninterrupted work.
Miscellaneous supplies can be considered on hand at the work place for a better workflow. These supplies may include brushes and brooms, tape, cable ties, tie downs, tarpaulins, and vacuums.
In order that welders and assistants may perform their jobs better, supplies of these safety and comfort products may be stocked at the working area. These supplies are as follows, but not limited to the list; eye protection, face protection, gloves, first aid, protective clothing, hearing protection, respiratory protection, and other such worker comfort product.

Help answer the question about welding
What's the best shade number for welding glass attached to a webcam which is used to record images of the Sun?Hi, I am trying to use a webcam (Logitech Quickcam Express) to take pictures of the Sun throughout the day for one of the projects I am working on. In order to protect the camera lens from being burnt by the direct sunlight, I think it might be a good idea to place a piece of welding glass in front of the camera. However, I need to determine the optimal shade number of the welding glass for my particular application. Does anyone know what shade number(s) I should choose? Thanks.

nice weld
very nice hand still
the metal isnt dirty enough to affect it. I certified with metal that looked like that
The fabrication of hull of large ships is normally done by panels assembled into blocks then the blocks are assembled into sections of the vessel and finally the sections are joined to form the hull.
First, panels consisting of plates and stiffeners are made. In the fabrication of the panels submerged arc welding is most suitable since most of the welding are made on flat surfaces and these can be done using automatic welding machines. Several of these machines can be run by a single operator
.For the assembly of the blocks however, most of the welding operations are done manually because automatic welding machines may no longer be suitable.
Manual arc welding is also used in the assembly of the blocks to form a section of the vessel and also for welding the sections of the hull together.
My suggestion is that you take one of those 6 week welding courses at the local college.
You just don't start by reading a book.
Now i have an office job, but i have been a welder fitter for 20 years.
Make sure the first thing you buy is a fire extinguisher
Hahaha I work at a Sawmill If the welders where I work cleaned all the metal before they welded they wouldnt be welding very much! I see them blast the metal quikly with a torch and then weld away!
get an arc welder that has at least 200 amps dc
a name brand such as lincoln miller etc
practice with the 6013
switch to 7018 for higher strength
mig welds are strong but brittle they will break without warning if overloaded
and yes i know a lot of shops use the mig on everything
but if they see what i see all of the time they wouldn,t
arc welds will usually start cracking before they fail
on the lighter metals you are talking about the mig would be ok or if you plan to do any aluminum welding
but if you want to go to heavier metal later the arc welder is better
most of my welding is done on 3/4 inch or thicker metal
i will use my mig if it is nonstructural
if you think what i say about a mig is not true try fillet welds on 1/4 inch plate then bend them
18v with 260 wire… I think you should use less wire, more like 190-210. But that’s just me. Weld would look flatter. Have a nice d@y! =)
Do not use welding glass. It does not protect camera lens at all.
Go to a store and buy appropriate filter even a bigger one and attach it to your camera.
making a triangle is a good technique
Have you guys seen “You Can’t Weld This!”? It’s pretty funny… The guys over at WeldingMart com had it made! Do a youtube search for it
I would like to see that weld cut open and sent to a lab for testing. HE DID NOT EVEN CLEAN THE METAL. Dirty welds have poor penetrations and are set up to fail. People, if you are too lazy to clean the metal, don’t weld.
The WPS is the specific directions instructing the welder in how to execute the weld. It would specify method (mig, co2, stick, submerged arc, etc.), material for the base metal and the filler metal, directions of travel, position of the weld (horizontal, vertical, angular, etc), voltage, and similar variables.
Any WPS must be qualified to demonstrate that it produces the weld characteristics that are desired. It then becomes the recipe so to speak for each welder to follow.
A WPS is typically written by a person experienced in welding.
You'll probably need a formal internship or apprenticeship. Especially in this economy, there's no shortage of experienced workers.
you may want to do a search on that (google). That may give u the help u need. Good luck!
Dont hold….!!!!
you use what is most comfortable you need to be able to see the puddle of molten metal to make sure you have good penetration and a decent looking bead I prefer a glass #10 and a glass cover plate how ever I'm thinking of buying a self darkening helmet as the price has come down to around $ 50 the auto darkening system has been on the market for about 15-20 years my brother bought one when they first came out and paid about $ 275 but the novelty wore off for him you can get a auto darkening from http://www.harbor freight.com Do not look at the light with out a welding lens as you will burn your eyes out!
welding is a physically demanding job, regardless of the type, most of the time you are sitting or standing for long periods of time, but it is also a great trade to have, if your asking about strength, it depends on the job, if you are production welding then you do not need to be very strong, but if you are a welder-fitter you would need alot of strength, because you would be handling material by hand and it can get pretty heavy, basically its up to you to know what type of welding you want to get into, and if you feel that it would be right for you in a physical sense. hope that helps with your question, good luck.
